Windows 7: BSOD after about 20 mins

10 Jul 2013   #1

BSOD after about 20 mins

Sometimes after about 20 minutes of running the pc starts to degrade it's performance. I notice that when opening and closing web browsers the mouse will start to drag really slowly for a few seconds, and sometimes switching between other windows causes it as well.

Sometimes it does not happen at all, but it almost always happens after about 20 minutes of watching a video or playing a game (any game or video). I notice that the frame rate starts to drop, some crackling sounds start to develop (coming form the speakers - this stops when muted) and the sound also starts to make other strange, bottley or tinny noises. If I close the game/ video or minimise it and switch windows the mouse drags again almost to the point of freezing, although the mouse drags a little bit in the video or game when all this starts as well (it's often the first sign so I know it's starting). I then have to close everything down and restart the computer.

This is the weirdest bit though. It must be a restart and it must be once the problem has started. If I shutdown and turn on again it has a chance of doing it again as it's a brand new bootup like before, if I restart it once it boots up it runs fine however long it's on until I shutdown again. If I restart after turning on the pc before the problem happens, then upon booting up it still has the chance of doing it. I have to wait for it to kick in, if it kicks in, before rebooting.

If I don't reboot soon enough it blue screens, and sometimes (very rarely but it just happened) it will blue screen after i click restart.

I have tried so many forms of diagnostics in the past but honestly it's probably better for you guys to check out the file at this point and I can let you know what i have tried afterwards. I say this because i did a complete reinstall a few months ago to try and fix it, which didn't, so i have only slowly been adding games and apps back to it since. this means this time around the pc is probably in the best state to try and figure the issue out.

Start by freeing up the start up:
Startup Programs - Change
Antivirus software is basically whats needed there.

Please remove Asus AI Suite. This is overclocking software and can lead to system instability even if you are not overclocking.

Start Menu\Programs\ASUS	Public:Start Menu\Programs\ASUS	Public
Start Menu\Programs\ASUS\AI Suite	Public:Start Menu\Programs\ASUS\AI Suite	Public
Two threads that were recently solved by removal of the software:
Recurring BSODs before/after startup
Windows 7 32bit freezes at random

Uninstall it using the free version of Revo Uninstaller. While uninstalling a software, opt for advance uninstall. This allows you to remove and delete registry left over of a stubborn program. Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems

Run a system file check and disk check on your Hard drives:
SFC /SCANNOW Command - System File Checker
Disk Check

Test RAM with memtest86+:
RAM - Test with Memtest86+
Pay close attention to part 3 of the tutorial "If you have errors"

Make scans with the following:

Kaspersky TDSSKiller - TDSSKiller Rootkit Removal Utility Free Download | Kaspersky Lab US

ESET online scanner - Online Virus Scanner Eset

Windows Defender Offline (optional)/in case above two show infection) - Run Windows Defender Offline

Do post back with results.
