Acer Aspire V3-571G-6622 :: Won't Recognize NVIDIA GeForce GT 730M Graphics Card

Nov 14, 2014

I was playing Minecraft two days ago using the GeForce GT 730M graphics card not the integrated Intel HD 4000 graphics card when suddenly purple squares appeared on the game screen. The purple squares didn't appear any where else. The game crashed saying I had a bad driver. Then the laptop pop a blue screen saying VIDEO_TDR_FAILURE. The laptop restarted as usual. I had this message before but further problems occurred. But this time is different.

After restarting I re-launched Minecraft but the game crashed saying I had a bad driver. I uninstalled the current driver using the programs and features and reinstalled the driver for my laptop found in Acer.com. The issue still continued. I went into Device Manager and found out that the graphics card had a code 43 issue. I found a solution online that said to install the newest driver on GeForce.com.

I did that and it seemed to remove the code 43 but when I went into NVIDIA GeForce Experience it said that my laptop didn't have a NVIDIA graphics card. Thinking it could of been a option that I changed that caused this, I did a refresh, and system restore to still see that my laptop wont recognize my NVIDIA GeForce GT 730M graphics card and that NVIDIA Driver Support Service was gone. It allows me to see when the NVIDIA GPU is in use. The system was cool when I started playing Minecraft when the problem happened.

System Specs:
Acer Aspire V3-571G-6622
NVIDIA GeForce GT 730M with 2 GB of dedicated VRAM
Intel HD 4000 graphics
15.6" HD LED LCD
4 GB DDR3 Memory
Acer NPlify 802.11a/g/n + BT4.0
Windows 8 64-bit

Acer Aspire R7 571G :: Looses Connection To GeForce Video Card

Oct 12, 2014

I own this model since May 2013, and all this time I have this problem:
 
In my drivers list the NVidia GeForce Mobile sometimes is present and most of the time not.

When it suddenly appears it will stay for a few days or weeks and I can play all the modern games happily. But then something will happen computer will reboot and the driver is no longer in the list, and for month until it will appear suddenly again.
 
This already happened about 5 times. Unfortunately I cannot go to the repair because I bought this device in Taiwan and now I am in rural Russia.
 
I suppose it might be a microcrack in the PCB or maybe a bad sensor or a bad cable, who knows. This is definitlely not a driver or software issue. Or is it?
 
This device is very good, but without GeForce it looses about 25% of it's value.

HP Pavilion G7 2269WM Networking :: External HDDs Disconnecting WiFi?

Oct 19, 2014

HP Pavilion g7 2269WM  W/ Windows 8.1(64bit)
 
I recently purchased an Insignia powered USB 3.0 hub to connect 2 External HDDS to my PC via 1 of 2 USB 3.0 ports. 
 
HDDS -
 
1. Western Digital My Passport Ultra 500 GB
2. 500 GB SATA drive from another laptop put in an enclosure.
 
Both work just fine plugged in alone, plugged into the hub with the hub plugged into the NON 3.0 USB port.
 
But the second I plug the hub into a USB 3.0 port, wifi goes out, and sometimes 1 of the drives are not found.
 
When I unplug the hub, wifi continues to work.  
 
I have tried doing this with the hub plugged into power and not, same results.  What is the issue causing a wifi issue? I dont understand how any of this is even related to a network connection.

Dell :: Switiching HD From 6400 With NVidia Card To Intel Card?

Sep 25, 2009

Just swapped out my e6400 with the nVidia 160M GC fro a 6400 with the Intel card (due to heat issues).

I tried just swapping the hard drives so that I wouldnt have to reinstall the OS.
Its not letting me start Windows.

I think the issue is that I dont have the drivers on my older HD for the new motherboard/GC.

Acer :: 4720Z Wifi Card Goes Poof

Apr 29, 2008

I did some searching and couldn't find the cause for my 4720Z's wifi card just disappearing about twice a day!

I'm still running Vista Premium but I have something deleting the Wifi adapter from Device Hardware list about, at least once per day, and not at the same time each day.

I don't know if billy is just throwing a tantrum or which software / hardware (could be Acer installed stuff for either or both!) As mr gates doesn't like other people installing anything but what he sales!

So I start out in Safe Mode, and my audio doesn't work, but my wifi card can be used and doesn't go POOF!

I flip a coin on what I'm going to live without, audio or wifi!

The 4720Z is 3mos old and has been doing the magic trick with the wifi card ever since the 2nd or 3 wk, and I don't know how to find the conflict?

Acer :: Will Allocating More RAM To My 5920 G's NVIDIA GeForce 8600 M GT Graphics Card Improve Performance

Feb 11, 2009

I have a Acer Aspire 5920G (Vista Home with SP1) laptop which I use for general purposes as well as occasional DVDs and a little games.

With the kind help from members of this forum I upgraded the RAM from 2GB to 4GB a couple of months ago but of course my 32bit Vista only uses 3GB which leaves 1GB unused. The laptop's processor is a T7300 at 2.00GHz.

Its NVIDIA GeForce 8600 M GT graphics card (with latest driver installed) seems to work quite well but a friend who I occasionally game with said I could go into the BIOS and allocate the unused 1GB of RAM to the card which will improve its performance.

I googled this to check but the articles I read (with my limited technical knowledge!!) seemed to say that allocating extra RAM in the BIOS does not work with dedicated cards and attempts to do so could in fact reduce performance.

I would be very grateful if an expert in this excellent forum who is knowledgeable about graphics cards could please clarify the situation for me.
Basically can I go into the BIOS to increase the card's RAM allocation to improve performance as my friend suggested or is this a waste of time and/or dangerous ?

Looking at the NVIDIA system info, I see that it says Total Available Graphics is 1535MB but dedicated video memory is 256MB. Does this support what my friend says or is it unrelated ?

Acer :: Aspire V3-571G With Really Noisy Fan?

Oct 22, 2014

The fan of my computer has started to make a lot of noise as of yesterday. It's alright the first 5 minutes after start-up but then it goes crazy as long as the fan is running fast. The core temperature is around 47 C on both cores so it's not even that hot and I recently open it up to check if it was dust covering the fan but it was fine (I blew away as much dust as I could but there was really nothing on it). 
 
Here's a video of how the noise sounds : [URL] .........

In the end of the video you can hear the sound at the fan intake
 
 Computer specifications
Acer Aspire v3-571G
Intel Core i5-3230M 2.6GHZ
Windows 8
Bios v. 2.21
Bought August 2013
  
What should I do? Replace the fan? Is it dangerous to run the computer when the fan is making this noise?
 
My computer has become pretty slow latetly and therefore the fan is running fast more often, maybe it works to make a factory reset?

Acer Aspire E1-571G :: ERecovery Does Not Start Up After Alt+F10

Dec 29, 2014

My boyfriends computer has "crashed" after he tried some "optimizing" last night.
 
When at the login page, it freezes before it is possible to write the password so access to the computer is not possible. 
 
Has checked F2 at boot and D2D is set to be enabled.
 
When I click Alt+F10 at boot up, it says "wait a minute" where after it loads the windows 8 layout, not the erecovery tool as shown in the video by acer.
 
How can I check in the bios whether the recovery partition is corrupt or what else to do? 
 
No recovery disks has been made.
 
It is an Aspire E1-571G laptop.

Acer Aspire V5 571G :: No Access To BIOS

Nov 29, 2013

I can´t enter BIOS on my notebook, I don´t know what´s the problem what to do now.
 
What did I do? I had Windows 7 installed and everything worked well. Then I decided to install Debian GNU/Linux instead. That worked as well, though I had some issues with wifi connection and the system did not shutdown properly. That´s why I wanted to reinstall Windows. In order to boot from DVD, i had to change the boot order, because Debian always changes its own boot priority to max - so at this point BIOS was still working! During Windows 7 setup, I formated all HDD partitions, created new ones and BAM! Windows 7 would not installt because it has some problems with GPT partitions, it said it could not install to this partition (I tried all). So I canceled the installation and restartet the system. Of course now it printed "Operating system not found". I could not even enter  BIOS (allthough it showed the normal message "Press F2 ..." and the Windows 7 installation had trouble finding some drivers, so it did not even start correctly. The Acer Recovery I created from Windows 7 (before installing Debian) started, but it failed to copy the first file and ended. So nothing worked. However, I could install Debian again, which is now my OS.
 
Current situation: OS is Debian 7, it´s working, but I have many problems with it (cannot change display brightness, often looses wifi connection, instantly reboots (!) after shutdown) Can´t enter BIOS: I have tried F2, DEL, ESC, F10, F12 without success. Debian is again at boot priority #1, and I can´t change it without BIOS (so not able to BOOT from DVD etc) I have tried to short the G2201 contact (service manual describes how to use it to remove BIOS password), no success. Maybe it´s import that I use GRUB bootloader, which was automatically installed with Debian...
