Acer Aspire 571pg :: FPS Drops On Games - Overheating?

Dec 2, 2014

Recently i buyed a laptop (Acer Aspire 571 pg) this laptop is very good for browsing and watching videos, etc... I'm happy that it can handle those things perfectly But i have a big issue when i try to play some games.For example GTA IV. I start the game normally and after a couple of minutes the game stutters/ drops fps constantly. I mean... It runs well in the first 4-5 minutes, then it starts to run slow for a couple of seconds and then goes back to run normally for another couple of seconds, and then again the game runs slow, and this keeps going and going as long as i play.

Specs: [URL]... HDD: 1tbO.s: Windows 8.1 [It was originally Windows 8, but i updated the Os for free] (Maybe this was the problem?)RAM: 8gbVideo [1]: Integrated Intel HD Graphics 4000Video [2]: Dedicated Nvidia 710m [1gb] ddr3Processor: Intel i7 3537U 2.0ghz [2.5ghz in turbo]

So I really don't know what to do, this fps drops are really annoying. I've tried:

-Installing new video drivers [They're up to date]
-Installing new audio drivers [They're up to date too]
-Changing battery settings, doesn't make much difference in balanced mode or high performance
-Low the settings and resolution of the game [This keeps happening even on the lowest settings, it stutters/ it still gives me a fps drop]
-Defrag my hdd [Nothing changes]
-Updated my bios [The problem still persist]
-Turning off vertical sync and other various settings on the Nvidia control panel.

The thing is that i used Nvidia inspector just to check the gpu temperature and i notice that when the temperature reaches 60 to 70 celcius degrees the game starts to run slowly and stutter. I've this cooler connected to my lap: [URL] ... I've the same pad just in color black.But even with that thing connected the temperature still goes up. Maybe i need a better cooling pad? What should i do to get the fps stable?

Lenovo T400 / T500 :: ThinkPad T540p / Unable To Select UEFI / Legacy Boot In BIOS / Startup

Aug 7, 2014

I bought a ThinkPad 540p that comes with preloaded Windows 8.1. As I want to dual boot the machine I tried to select the Legacy Boot option in the BIOS/Startup tab, but I can't do anything as the option UEFI/Legacy Book is greyed out and locked in "UEFI Only". Below it there is an option called: -CSM Support that is also greyed out and selected as [No]. (below  these options there is a little note with an asterisk saying "Unselectable for Secure Boot").
How can I enable the UEFI/Legacy Boot option again in order to dual boot the computer? I want to be able to boot from USB or from the CD Drive.

I have a Acer Aspire E5-511P with bios Insydeh20. On UEFI it does boot USB-drive, even with passwords set. It boots on USB-drive with legacy set, but now my Wifi doesn't work. On older laptops no issues with UEFI, I just had to set boot order. And Wifi works just fine.

Acer Aspire R7-571 :: Locks 3 Min After Boot With BIOS 2.09

Oct 28, 2014

I recently updated my bios on my R7-571 and it has caused me great woe.  My computer will lock hard between 3 min and 3:30 min after bootup if I don't disable the WIndows Managment INstrumentation service.  THis of course caused other problems on services that depend on that like LogMeIn.  I need a solution to this.  Either a way to downgrade to an earlier bios which I don't think is possible without a version of the bios updater that will support this, or a newer bios that addresses this issue.

Acer Aspire V3-371 :: Cannot Boot To MS Windows After Upgrading BIOS Form V1.05 To V1.08

I just buy an Acer Aspire V3-371, then I delete all partitions in HDD and install MS Windows and driver for this notebook. Everything are OK until I ugrade BIOS form v1.05 to v1.08. Now, it cannot boot to MS Windows and shows me "No Bootable Device".

Acer :: Boot Issue On Aspire 2930 Laptop Corrupted BIOS

May 9, 2010

The strangest thing has happened to my Acer Aspire 2930 laptop today.

I shut it down last night as I normally do, then this morning I turned it on and it wouldn't boot. It goes through BIOS and startup, but then it stops. It doesn't start loading Windows XP from the hard drive, it doesn't recognise boot CDs/DVDs. When I go into the BIOS, everything looks normal except the boot portion. There are several options there, but they don't say what they normally say. For instance, the first boot device, the hard drive, is completely invisible. What I mean is that the option is just not there, but when you move the selection around with the keyboard, you can tell it's supposed to be there. Look below for a better explanation. The other options are there, but they aren't recognising the devices. I have a friend with the exact same laptop and her BIOS shows everything as it should be. She's here now and I'm typing this on her laptop because I now have two dead computers here at home.

I don't get it. It's almost like the BIOS somehow became corrupted. I didn' t even know this could happen without attempting to flash the BIOS or something, and that's not what happened. I have never flashed the BIOS on this laptop. Not only can I not figure out what happened, there doesn't seem any way to fix it. I mean, if the laptop doesn't recognise any devices to boot from... I was thinking about taking it apart and resetting the CMOS, taking out the battery. I think that's the best I can hope for at this point.

I don't have any way of cloning the BIOS from my friend's computer so I guess the next step would be to get a new BIOS chip if the CMOS reset doesn't work? The laptop is unfortunately one month over the one year warranty. I read that there's a way to get the laptop to read an external USB floppy diskette drive regardless of the status of the BIOS, you are supposed to hold the function key plus the escape key or something when you turn on the laptop a couple of times, and then it magically reads from the floppy drive. I would have to somehow buy or get a drive, but I haven't even seen such things in years. Things I can try?

Here is what my BIOS looks like compared to my friend's:


2. IDE1 :
3. USB FDD :
4. Network Boot :
5. USB HDD :

My friend's:
1. IDE0 : Hitachi HTS542525K9SA00
3. USB FDD :
4. Network Boot : Realtek Boot Agent
5. USB HDD :

As you can see, there is definitely something wrong with my BIOS and I believe that's what is causing the computer not to boot.

Acer :: Aspire Timeline 5810tz Won't Boot, Can't Access Setup Or Bios

May 7, 2010

I just got an acer aspire timeline 5810tz, which came with vista, so i was in the process of reformatting it to have XP, which i've done several times on my previous laptops. When i changed the bios to IDE, which is what i read was the correct setting (perhaps this is where my problem is?), i found that i could no longer boot the computer or access setup, bios or the boot menu. When i attempt to do any of these things, the computer just sits on the logo screen.

i'm getting fairly desperate at this point, having tried a large variety of solutions, key combos, removing the battery, etc.

Acer Aspire 5810TZ :: Flashing BIOS - Boot It Up And It Just Showing Logo

Mar 13, 2013

Flashing the bios. I have a Aspire 5810TZ. I boot it up and it just says 'acer' and won't go any further. I went to the download page for BIOS on and it has a zip file with 5 files:

JM4151135.exe FLA... GPC_V135.bin readme.txt FLASH.BAT

What do I do? I have tried copying the files to a USB and powering on with Fn-Esc held down. After letting go of the power button and holding Fn-Esc a different screen appears after 30 seconds. I let go and have given it 30 minutes but it is not doing anything. I have read online from other people the power button should be blinking. Do I need to rename one of the files.

Acer Aspire M :: Boot Configuration File Being Invalid - Cannot Access BIOS

Dec 26, 2014

My Aspire M laptop will not boot due to the 'boot configuration file being invalid', at least, this is what the 'Recovery' blue screen states.  The blue screen offers to 'Press Esc for UEFI Firmware settings, but is not responsive.  I've tried F2, F8, F10, Alt+F10, F12, Space Bar, Delete and Break to try to activate the BIOS interface, all equally unsuccessful.
I followed the instructions to purchase recovery tools from Acer, but without being able to access the BIOS to set the boot order, I've just sunk another $25 into a laptop that doesn't work. The cost of service exceeds the cost of the laptop, so I'm inclined to continue trying to repair it myself.  If it cant' be repaired, there is little chance I'll purchase a new Acer to replace it as this has been a very frustrating experience.

HP Envy 15-U010DX OS/Software :: Disable SecureBoot And Enable Legacy Boot

Dec 9, 2014

I have been trying to disable SecureBoot and enable Legacy boot. This is a fairly straight forward process, press F10 to enter the BIOS, scroll over to the proper area and press F5 over Legacy boot to enable it (Which automatically disables SecureBoot). I have tried this quite a few times and each time have had no success. Everytime I change this setting and restart the computer it just ends up with Legacy Boot disabled and SecureBoot enabled. Yes, I am saving the settings, if I change other settings (Such as Virtualization support) they do save. Why I cannot save these settings after changing them?
I have an HP Envy 15-U010DX. I have also updated the BIOS and am running the latest version.

Acer Aspire 7740-5691 :: Boot Screen Freezes With Pixel Distortion At The Top - Reset BIOS

Oct 21, 2014

I have an Acer Aspire 7740-5691. The boot screen freezes with pixel distortion at the top. I've tried all the restore discs. I found where some people referenced a similar problem with other computers and they were fixed by resetting the bios. I can't figure out how to do that. There's no place for that in the boot settings option and there's no visible coin battery to temporarily remove to reset.

Acer :: (6935G) Boot Problem After Restart (cant Access Bios / Boot From Disk Etc)

Jan 9, 2010

I got this laptop a few days ago, I currently have 7 and XP installed on it and kind of have vista...(read further down).

My 7 seemed to break today after playing around with a program called powerstrip trying to get my external monitor to show the right resolution (I've realised now the cable vga was broke, but meh) but this is not the full problem, after windows 7 failed to boot I tried to boot xp after turning it off during the windows 7 splash screen and now im stuck with a dash when I turn the laptop on (I dont know if its actully related to something I've done or not).

If I turn the laptop on a flashing dash comes on in the top right, it then stops flashing and turns into a none flashing dash further up the screen and just locks here and I cant do anything at all other than trying to restart it. When I had this problem previously (at least I think this problem) on my desktop it usualy turned out to be something usb related but I have everything unplugged (all though the bluetooth adapter light is on when it is doing this) so I realy dont know what to do...............

Acer :: Cracked Back Cover On My Aspire 9410

Dec 5, 2008

I've found a source for the replacement part through EXTENSIVE research- and found an online user manual. I am not used to building/opening laptops, so I don't know whether
I'll need special tools to replace the broken back cover; are there any other parts I may need (such as hinges, antenna WiFi).

Is this even a job I should take on or is it pretty easy?

The LCD is fine- it's JUST the plastic cover I need to replace.

Acer Aspire One D225e :: Lost WiFi Connection - Can't Get Back On

Dec 25, 2014

I've been using my netbook at my local library for 3 years. Acouple weeks ago, all of a sudden it lost contact with the library's wifi connection. The librarian tried everything he knew, no results. I later borrowed a laptop from the library, looked up fixes, tried them, but they didn't work.

Here's what happened: Got a padlock with a window saying failed to connect to a Windows service. The dependency service/group failed to start. A troubleshoot resulted in a yellow triangle with an exclamation point in it, saying network proxy settings can't be detected, though it also says detected.

Trying the fix on Acer support--checking to see if TCP/IP is working right--resulted in an error message, TCP/IP improperly installed.
Trying rewriting the registry keys didn't work.
Ditto the remove/reinstall network driver adapter.
Finally it said if this doesn't work, there's likely a hardware problem.

HP Pavilion 17 Recovery :: Bios Recovery From Legacy Csm?

Jan 28, 2015

I changed my HP to boot with legacy CSM, but I couldn't boot from the Windows 7 boot disc.  The laptop was shipped with Windows 8 configured for UEFI boot before my change.   The screen after boot is blank and now I can't even get to the bios menu. 
I have tried a Windows 8 USB recovery drive, but the computer doesn't seem to try to boot from flash, even with the hard drive disconnected and the CD tray open. 
I watched a video of a man disassembling an HP Pavilion completely down to the base plate, but I did not see a back-up or RTC battery anywhere in the computer.  If I could find the bios back-up battery for removal or reset the bios somehow with the hardware, i would do that.  I waited for 4 hours without the main battery attached without any change.  At this point I don't know if this model Pavilion even has backup battery. How to reset the bios to default UEFI setting without a bios menu? Note that pushing F2/F8/F9/F10/F11 and a whole bunch of other keys does not bring up the bios menu at boot time (like it did when it was in UEFI mode).
My next steps are to use the HP Recovery Media application on a 2nd computer to create 6 Window 8 DVDs and see if these will boot from the CD.  If that doesn't work, I'll contact HP support and see if they can send me a custom recovery disc. 
It seems strange to me that I can't even get to a bios menu in legacy mode.  Is this normal?  I suspect that my configuration change corrupted something and no booting will work any more.  If booting from disc doesn't work, I think I'm stuck with trying to drain whatever back-up power source keeps the bios in-state, however long that is.

Acer Aspire E1 522-3657 :: Default Boot Device Missing Or Boot Failed

Oct 11, 2014

I have a Acer E1 522-3657 computer, which my son set-up for me but did not make the recovery disc(s). The unit is just outside of the warranty period when the hard drive failed. The hard drive just makes a clicking noise and after the logo screen appears it goes to a blue screen with a box that has the following message with in, "Default Boot Device Missing or Boot Failed. Insert recovery Media and Hit any key.....Then Select 'Boot Manager' to choose a new Boot Device or to Boot Recovery Media.
I have installed a brand-new Western Digital 1T Sata3 harddrive to replace the Toshia 750 GB original Drive. After turning the computer on and at the logo screen I press and hold F2, this takes me to the InsydeH20 Setup Utility Screen. I see under the "Information" menu that the installed harddrive model and serial number appear. I see in the "Boot" menu, Boot Mode: "UEFI" and Secure Boot: "Enabled".
Under the "Exit" menu, Exit Saving Changes is highlighted. When I press F10 a "setup Configuration" box appears asking to save configuration changes and exit now? "Yes" is highlighted to which I hit Enter and are returned to the "Default Boot I then hit ecs twice and are at a black screen with the message No bootable device -- Please Restart system_appearing in the upper left corner of the screen. I then push and hold the power button until the computer shuts off.
I have ordered from acer the "Acer E-recovery Media Disc Set", which is specific to the SNID of my computer. I have not attempted to format the new hard drive in any way.  I assume the E-recovery Media Disc Set will handle that operation due to the multiple partitions required.
In view of the above situation, do I need to set up the computer in any way before I start to utilize the E-recovery Media Disc set. I assume the Media will be on CD's. The computer was running Win 8.0 which was updated to Win 8.1 and was running very well, very stable.
