I have had some strange BSOD lately all with different issues. I have updated my bios and since that, my original (the drivers that came with the nvidia card) drivers would be unstable in the system, causing a BSOD with irql_not_less_or_equal. I also had many artifacts on my screen including sudden system freeze, where half my screen was black and the other half normal. This lasted a few seconds then everything was normal but after a minute the computer would freeze forcing me to do a hard reset.
In light of this i decided to update my drivers to the very latest, while i was updating i got a BSOD and decided to uninstall the drivers again and reinstall them, the second time around i was able get it installed, no BSOD. Now i dont get the massive instability that happened when i had the old drivers installed, instead what happens is when i'm doing something that graphically intensive it will for example, in bad company 2 it will flash the screen really fast with black flashes repeatedly (after a few hrs play) until it randomly decides to stop. In starcraft 2 (usually after 30 minutes), the system will hang, the only thing that works when this happens is the audio, i cant even get ctrl+alt+del task manager to open, forcing a hard reset.
In the odd chance that it doesn't crash or hang during play, it will 90% of them time hang and freeze (with only audio working), right after i exit a program that taxes the GPU, such as Starcraft2 or Bad Company 2 (as examples), but it also does it with Maya 2012 while rendering in mental ray which isn't good for me that it happens then.
I ran memtest86 i tested all 10GB and it did not fail any of the tests ( 6GB i just installed 6 days ago).
Ran new Vid card drivers from the Nvidia website
Running Vista 64bit Home premium
800w ATX power supply
i7 920 @ 2.67
MB: Gigabyte ex58-ud4p
GPU: Nvidia GTX 260 by EVGA
i have mini dump files available if someone could point out to me how to insert them in this forum.
Anyways hope this helps (info wise) i just want to know if the GPU is slowly dying on me.
I just downloaded and installed not to long ago SpeedFan, everything seems to be around the ranges of 38C - 43C, except for the GPU that idles at 48-49C and when playing a game jumps to 69-73C. I dont know if that is normal or not but i read that video cards usually get that hot under stress and that it should be ok to be around 75-85C, but ofc i could be wrong.
UPDATE: I upgraded my OS to Windows 7 Home premium and updated everything i could, including MOBO drivers, mouse, keyboard, NIC card, did all windows updates related to windows 7. The problem still persist but i dont get a legitimate BSOD, instead my computer hangs with no warning, just freezes, i can hear sounds and i'm still connected to the internet. I know this because i was on Skype one of the times it froze and i could still talk to the person and that required being and using an active internet connection. So i dont think its sound or internet related. I used EVGA OC scanner to check my video card and ran a 1hr stress test which brought my GPU to 86C and it ran the test without freezing, i also used furmark and did 15 bench mark test and it only froze in one occasion, but i retried the same test that froze it up and it passed it.
I looked in the event viewer and got nothing, but in safe mode i get these error in event viewer about the same time the hang-up occured.
DCOM got error "1084" attempting to start the service WSearch with arguments "" in order to run the server:
The following boot-start or system-start driver(s) failed to load: discache
what are these drivers in bold i have got no clue
can they be the culprit?
Yes actually i did, and it was exactly what i thought i was, the video card. I ended up getting my Video Card that was defective and tested on a friends Rig and it did the exact same thing. So immediately i knew that was the problem. I bought a gtx560 and never had a single issue since i switched them.
