Acer Aspire 5742 :: Rebooting Continuously Running On Windows 7
Sep 3, 2014
I own an Acer Aspire 5742, model no. PEW71. It is running on Windows 7. I included a vid for you to see what the problem is: [URL] ....
So, as you can see, the computer can be turned on, but it doesn't get through the acer screen on to the windows picture, and it automatically reboots and shuts itself down again over and over again. This has happened in the past, but the repairers have reset the operating system and BIOS. They also switched the hard disk for a new one, but this could be because of some other problems I was having (USB channels weren't working).
Everything worked fine for a month or so, and then it happened again. I myself am thinking about the motherboard being damaged.When this happened in the past however, I was still able to turn on my PC sometimes, so I was also able to save my files. Now on the other hand, I can't get the computer on anymore. The most important thing to me is saving the files. After that, I'll take it away for reparation again, where they will probably delete everything again (I can't commicate with the repairers myself, so I can't discuss terms or anything).
At the end of the vid you can see me turning off the computer by pulling out the adapter. Removing both the adapter and accu is the only way the computer can be turned off. Even shutting it down by pushing the on/off button for 5 seconds will not prevent the auto re-boot.

I have an Aspire 5742 factory loaded with Windows 7 and it worked for 3 years. Now, Microsoft is sending me 'Unauthorized Windows' messages. The hardware has not changed. Microsoft checked and said my OEM product key is fine. Restoring to a previous point failed to fix problem. I just ordered the eRecovery DVD. Is there a way to fix this without wiping the system and starting over? I have a LOT of software installed that I will hate to lose. BTW - my best guess is that malware caused this.

At some point during the day, the sound on my Acer Aspire 5742 (running on Windows 7) ceased to function. There is no sound on any internet browser, and the normal notification audio is also not playing. I have checked the mixer and everything is fine. I have checked the speaker properties, which says that the Realtek Audio speakers are enabled and working properly. However, when I try to test the speakers a message says 'Failed to play test tone'. The weird thing is that Spotify is playing totally normally. I have tried shutting down Spotify and restarting it. I have tried turning my computer off and on again.

Got an acer 5742 running windows 7. All of a sudden the display has stopped working.
It boots fine and the display works up to the point of "starting windows". I see the windows logo for a bit then it goes off.
If I plug into an external display it works fine. In graphics properties, the display isnt even listed (only the external display shows up).

I'm sure I have a virus that won't let me do a full scan on Windows Defender (only quick). It won't list ACER's eRecovery option. How may I do a factory reset? This is an ACER Aspire 5742-7653.

I have an aspire V5-572 notebook with win 8.1 and the only partition. I made 2 more partitions using AOMEI partitioning tool. after rebooting it shows the usual win 8 loading screen but no display comes then. complete blank screen and no desktop.
1. I assume the partitioning was done perfectly as there was no error message
2. OS loading accordingly without any warning or error message
3. At the black screen the mouse movement showing and sometimes the wifi symbol flashing up at the almost middle-bottom of the screen.

I have an Aspre 5742 which is a couple of years old now. It is running Windows 7. I have been trying to output the display to my TV but it is not working.
When using the HDMI connector there is no output whatsoever. I have followed the suggestions on the Acer website about detecting connected monitors but this does not detect my TV ...
When using the VGA output the deTect function detects the presence of the TV but the TV does not detect the computer.
I have connected another computer to the same TV using the same cables (HDMI and VGA) and everything works just fine.
I have updated the video drivers on the Acer but there is no change.
A few months ago we had to change the hard disk as the original packed in. I put in the same model disc as I took out and reloaded tyhe software from the rescue disc. Prior to this the HDMI worked perfectly.
TV is a Sony Bravia

I have been using this small utility for caps lock on a 5742 using W7 Pro and it works well. The 5742 doesn't have a caps lock light or indicator built into from Acer, so one have to come up with something.
This program will place a red "x" or green "check" in the taskbar letting you know if you're in caps lock and will also produce a small "beep" after a few letters typed in if in caps lock.

My Acer 5742-7653 is stuck in reboot loop. It starts to load Windows 7, and then the screen goes black, and it beeps a bit, and theen starts over again. The F2 button no longer gets me into Setup. And the F12 doesn't work. I can't get into SafeMode or Setup. When the problem first began, I could sometimes get into Setup and boot from an external HD which as a diskImage.
I used to be able to remove battery, and remove HDD and RAM, and then it would boot up from the external HD. To get through a busy period at work we set the power option so the computer would never shut off. But this is creating problems with all the Firefox, Adobe and Windows updates that want to run.
This is running on Windows 7, 64bit.
How can I determine if this is a problem with the HDD, or the RAM? or Motherboard? What else could it be?

I've run the Win 7 upgrade adviser and it says the system can run Win 7 as it has CPU 1.6 Ghz and 2.0 GB of RAM. However in the device section it says that the Mobile Intel (R) 915GM/GMS, 910GML Express Chipset Family is not compatible - driver not compatible with Windows 7 . Is there a driver I can download to fix this problem? I've checked the Intel download web site but can't determine whether a driver exists or not ??

I have changed the Windows power settings so that when I close the lid it goes into hibernate mode. However, when I open the lid it does not start the laptop and restore from hibernation. I have to open the lid and press the power-on button and then it restores from hibernation.
I have a much cheaper Toshiba Laptop that just automatically starts and restores from hibernation when I open the lid. As far as I recall there were no special settings that I changed in order for the Toshiba to work like that, just the setting in the Windows power option that permits hibernation when closing the lid. The Toshiba run Windows 8.0.
Does this model Acer have this feature? If so, how do I set it up to work?

I'm seeing the following:
600 MB Healthy (Recovery Partition)
300 MB Healthy (EFI System Partition)
449 GB Healthy (Boot, Page etc...)
15.5 GB Healthy (Recovery Partition)
Given I'm supposed to be running OEM Windows 8.1 shouldn't 1 of the first 2 partitions say OEM?
If that is so I know what I've done and it will probably require a recovery disk to set things straight (i.e. recover the original Acer version of Windows 8.1). This is a follow-on from a previous post where I foolishly installed an evaluation copy of Windows 10 instead of running it using virtual software (which is what I usually do with these things) - I can't remember for sure but it's likely I installed it by formatting the whole disk and probably wiping the OEM partition.
I do have a system image taken a few days before I installed W10 but suspect the OEM wasn't included...which is what is displayed above after I reloaded it.

I am having an issue with my Acer Aspire V5-431P-4653 running Windows 8.1, namely, I cannot adjust the screen brightness at all. It seems to arbitrarily select a brightness level upon start up and from that point I cannot change it via the Fn and directional keys or through the control panel power settings. I have owned the laptop for a year and a half and this problem began roughly a week ago.
Of note, when I attempt to use the Fn and directional keys the brightness icon that pops up stays at the frozen brightness level - it does not move at all. In contrast, when I open the power settings and attempte to change the brightness from there, the brightness slider will move wherever I drag it, but the screen's brightness itself does not change. At startup the screen's brightness may be at full, minimum or somewhere in between - but regardless it will not adjust.

I'm having major problems with connecting to the wireless network in the office. It sees the network, allows me to enter the security credentials, then connects (with confimed internet connectivity) but drops out after 10-20 seconds. I have tried the wireless network at a friend's house which worked ok without any interruptions, so it is definitely nothing wrong with the hardware. I'm using a brand new Acer Aspire V3-572-56T3 on Windows 8.1, with all the latest drivers/patches loaded and have tried fiddling with many of the advanced settings for the network adapter to no avail. I logged on to the router to ensure all settings, encryption standards, channels etc. were matching but the problem keeps persisting. This has been ongoing for two days now and is driving me insane as I really need to have wi-fi working in the office. Plugging an ethernet cable straight into the router works fine but it's not the ideal solution (and is posing an OH&S hazard as it is laying on the floor).
FYI I have run diagnostics several times & the one thing that stood out was this:
Diagnostics Information (Wireless Connectivity)Association status: Fail 0x00038002Association reason code: 0x00000002
Result of diagnosis: Problem foundIssue referred to: RNWF MSM Helper ClassRoot cause: Windows could not connect to "ERICSSON"You can try to connect again.
Result of diagnosis: Problem found

I have an Acer Aspire 5741-5698 running Windows 7. I never want to connect to the internet wirelessly. I only want to connect rarely with a wired connection. I can disconnect the wireless by pressing Fn+F3 but I never see a "Launch Manager". The problem is when I turn off the computer and turn it back on, it defaults to connect wirelessly. I went to Manage Wireless Networks in Control Panel and selected Manually Connect to my home Network. That did not work. How can I stop it from connecting automatically wirelessly?

My friend has mess up his Acer Aspire 5520G. And I'm supposed to help him fix it. His laptop has a nVidia 8400 graphics card.
When the laptop is powered it keeps rebooting itselve evry 3-4 seconds, and nothing is displayed on the screen. I don't know what's wrong with my friend's laptop but I think it might be related to the BIOS been correpted in his laptop. He tried to flash the BIOS from VISTA.
Anyways, I got Crisis recovery disk, and the latest BIOS for his laptop, and I got also a USB floppy drive. I removed the harddrive and the optical drive to force the laptop to boot from the USB floppy drive. I removed the battery too.
I pushed Fn+Esc, plugged the charger in the laptop and powered the laptop. The laptop know doesn't reboot itself but doesn't detect the floppy drive either.
I used the floppy to make a boot CD and tried to flash the bios again using the DVD drive this time. Pushed Fn+Esc again. The laptop turns ON and try to read the CD for about 5 seconds and then nothing else happens.
1- Is it a BAD BIOS.
2- How to make a boot CD to use with Crisis Recovery.

I just bought this new acer 3680 1 month ago because i needed a laptop for my studying. basicly all i need it for is to take notes from classes, and surf the web (youtube etc).
ok so basicly the first impression with preinstalled vista was horrible. incredible lag... 3 seconds delay at all times when browsing the web. and completely unable to playback any form of media with any other windows open without the sound lagging like crazy... all that kind of stuff
but the main problem seems to be the fan. It runs at high speed (producing as much noise as my desktop computer). The fan turns on aprroximately 4 minutes after you turn on your computer, or immediately after you open an application.. and it just keeps on running untill you turn off your computer... It is so annoying that i have trouble bringing the computer to class (which is where i really need it!) because i feel embarrased about the noise, and frankly i think this is an annoyance to the other students aswell. Is this a common problem with 3680? No one of the other students pc's fans run when they just use basic applications like word, or internet explorer, and they certainly dont do it when simply idling on the desktop.
furthermore it needs to be said that i have messed around with vista alot, and tweaked it in every possible way to remove pressure of the cpu.. and ofc removed all antivirus programs etc. Furthermore i tried installing XP, and guess what.... it took 5 mins of idling on the desktop in the brand newly installed xp for the fan to start again!!! so i conclude that the problem is not caused by vista overloading the cpu!. Does anyone else have this problem with their aspire 3680? maybe im just overly sensitive about the noise, but really it isnt supposed to run at all times.
