Computer Crash/black screen?

Leungwk01 · 1 Dec 2009 at 17:53

Guess I'll give this place a try to fix my problem.
I've a built computer which just suddenly crashes for no reason I can think off....
The problem occurs on stock and Overclocked settings from the bios and it suddenly just gives a black screen (forces me to restart manually).
Note: I've run prime95 for 24hrs no problem on overclocked settings/stock but the computer can sometime black screen when its idling.
Memtest ran as well no errors.
-----------------------------
Only thing I can retrieve to what has occurred is
"The default transaction resource manager on volume C: encountered a non-retryable error and could not start. The data contains the error code."

Taken from event viewer at the same time as kernel-power problem from event viewer.

(The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.)
-------------------------
I'm guessing its going to be a hardware issue but not sure which component.
Its going to be either CPU, mobo, GPU, PSU. Doubt it'll anything else.

Thanks for any help

On another forum, they said it could be with the bios settings which is what I'm trying atm.
I know for sure it won't be the HD as I've re-installed windows 7 on new HD.
I've tested the Voltages using multimeter and the volts being pumped out seems fine.
Wont be GPU as well because I'm using the same GPU on my new i7 build with no problem.

Which leads me thinking its either the mobo, cpu or RAM (but I tried 2 new sticks for corsair awhile which had the same problem)

The problem has occurred on XP, vista and now windows 7 so yes the issue remains.

The crash is unexpected because I can run prime95 for 24hrs with temps below 55degrees yet no crash. But sometimes it will just crash when the computer is idling. (nothing up just on desktop) and also when I'm playing games but not heavily only around 70% CPU usage.

The components was New. (every single part)
I've tested the RAM with memtest (test 5) which got 10 passes before I decided to stop it.
Passed the OCCT PSU, GPU and CPU test with no errors.
Swapping the CPU/mobo isn't really a option as the systems I own are different chipset.

The BIOS has all the settings set properly. (I think) So the vcore doesn't drop or anything.

It's going to be a pain to test them if I replace the CPU since the problem may not occur for awhile - Its happened once in the past 2 weeks, probably 9times in past 2months...

Well, I was told that it could be that there wasn't enough Vcore seeing as it crashes less when its overclocked rather than on stock. (weird I know)

I will see if it crashes when my GPU arrives tomorrow since I'm currently using same GPU to see if it crashes on my i7 which it hasn't. I'll be installing windows 7 on a new WD HD and report back.
However if it was the HD wouldn't it crash on my new i7 build (touch wood) which it hasn't.

I would test it now but 9500GT with newest Nvidia driver + windows 7 don't go well together. It freezes before windows 7 starts and CPU fans like crazy. Its fine without the newest driver.
Anyway, don't really care about that problem more concerned about the original one.
