Random lockups that seem to happen while playing games

[MajorFoley]

Hi guys, my computer has recently started randomly locking up lately, the problem is that it doesnt seem to be leaving any error messages so i cant find a log on what is happening. when i press my restart button my computer shutsdown and during post asks if i want to run in safemode or normal mode. Also when windows start no your system has recovered from a critical crash or anything like that

Any ideas? ive checked inside my computer and everything seems to be fine, no dust or anything in there.

That message is common, if you force it to shut down.

Lockup during gameplay may happen due to many reason.

Is the display driver not up to date? Update your ATI/AMD display driver.
You can get it from the link in our forum, http://www.sevenforums.com/graphic-...alyst-video-driver-windows-7-a.html#post17671, or you may go to AMD Graphics Driver and Software and opt for Automatically Detect and Install the appropriate driver for your card.

During installation, you may opt for advanced installation, and install the display driver only, not the Catalyst Control Center.

Is the GPU failing to work at a certain point of time?

Is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy.

Is the computer not blowing hot air properly? Dismantle it, clean the inside carefully. Specially clean the air vents and fan grills.

Is the RAM failing to perform? Test your RAM modules for possible errors.

Run memtest for at least 8 passes, preferably overnight.

Is the PSU supplying adequate power, specially during gameplay when the computer consumes more power than usual? Make it sure that the PSU is of sufficient wattage and it is performing good.

Moreover, if the GPU is comparatively old and not a high rend one, then it may miss some FPS during gameplay, specially for the latest and resource hungry games. Lowering the preferences in the games settings may make the situation a bit better.

If the games are online games, some other factors will also be added it the list. So let us know the situation after making the suggested changes.

Edit: if you dismantle, make it sure that the RAMs are at the most possible distance from the CPU.

ok ive checked video card its up to date, psu is definitely fine giving it the power it needs, i did however find some dust underneath the fanblades themselves, tomorrow i might get a small compressor and clean it out and see what happens, and after that ill run a stress test on the video card (the computer just about hit the 1 and a half year mark) and i custom built it so its relatively new

OK, let us know the results when the tests are done.
