DxDiag.txtcrashes.zipMinidumps.zipHey guys. First time im using this forum.

Alrite well my problem is that any PC game i play(Doom 3, Call of duty,etc.) basically crashes my computer within 15 minutes. When my computer crashes and i have sound on, the monitor(HP Compaq LA1905 Wide LCD) says it has "No source signal" and the sound freezes. Only thing i can do is shut down my computer.

I can surf the web, watch videos, open any program just fine. Only PC games crash my computer. Confusing me...

I gave you guys My:
-DxDiag
-Event Logs
- Few minidumps

I checked the tempatures and its not overheating. I tried reinstalling my display driver but that didnt help too much. The computer doesnt crash at all when i play Army Men: RTS or Stronghold 2.(Although stronghold 2 still does crash but after like 1 hour of playing whereas other games crash in 15 mins.)


If you need any more info please let me know.

Hi augdog99 and welcome to D-A-L.

I checked the tempatures and its not overheating.

And what are those temps? What did you check them with?

Is the interior clean of heat trapping dust? Do all fans spin freely?

Do you have a spare, known good PSU you can swap in to verify you are supplying good, and adequate power? I always like to know I am feeding good, clean, solid power when troubleshooting possible hardware issues.

I would also test your RAM. Here is my canned text on that:

You can test RAM using one of the following programs. Both require you to create and boot to a bootable floppy disk or CD to run the diagnostics. Allow the diagnostics to run for several passes or even overnight. You should have no reported errors.

Windows Memory Diagnostic - see the easy to follow instructions under Quick Start Information,
or
MemTest86+ (for more advanced users) - an excellent how-to guide is available here,
or
Windows 7 users can use the built in Windows Memory Diagnostics Tool.

Alternatively, you could install a single RAM module and try running with that to see if it fails. Repeat process with remaining modules, hopefully identifying the bad stick through a process of elimination.

Thank you for the welcome.

The temps. were at a steady 30-33*C for both cores. Core #0 highest temp can only go to 35-37*C while Core#1 can go up to 40*C. Im using Core Temp. I will have to check it when i get home, but im sure there must be a few big dust bunnies in there. No clue about the fans.

I'll ask my dad if we have a good PSU. I have a feeling it could be my PSU.

No problems detected at all with the memory test/diagnostic.


And thanks for your quick hellp

No problems detected at all with the memory test/diagnostic.

That's good but you didn't run it very long. They are not conclusive anyway so it is best to let it run for several passes.

And do note even a top quality PSU from a good maker can fail or be under powered for the demand.

So do i just keep testing it and testing it??

Yeah thats true... i hope it didnt fail because like 1 month ago it was workin fine then it just went bad after i installed Steam.

Well, I usually test overnight - Did it complete at least one pass? Typically, IF these testers find anything, the do so on the first pass. But with intermittent problems, you often need multiple passes.
