First Build, trouble finding bsod source

post #1 of 5
Thread Starter 
EDIT2** It seems it probably is the motherboard. NVIDIA is working on a fix http://nvidia.custhelp.com/cgi-bin/n...i=&p_topview=1
EDIT** It's a long read b/c I detail the attempts I've made to locate the bsod source.

A couple months ago I took the plunge and built my first system.

The current specs on it are:
q6600 w/ zalman 9700
780i mb
8gig ddr2 800
8800 gtx

Everything is great when it runs... but it's had bsod issues since it was built. This was before any overclocking, and since then I have tried underclocking, yet the problem persists.

I was hoping someone may have a thought or suggestion about how to locate the source of the problem--my guess was either a bad video card or a heat issue but I tried underclocking and rma'd the card but have the exact same issue. Well, core temp shows the processor doesn't break 55c even when o/c to 3.5ghz.

The bsod is pretty specific, it only shows up during video/gaming, not when I run stress test on the processor or during other activities. It doesn't show up all the time though.

Initially I get short multi-colored horizontal lines on the video/game I'm playing and over my cursor (otherwise they don't show on the desktop). If its just a video playback then they will slowly get worse, but it will continue playing back for hours (I fell asleep with a movie on replay and woke up with the artifacts on the screen), but it will freeze and give a bluescreen if I move the mouse. If I'm in a game, it will usually show the lines and bluescreen pretty quickly after that.

Hopefully somebody has seen something similar and has an idea of what could be the cause. I think the video card is ruled out as it was just rma'd and the problem persists. I doubt it is the processor as it runs cool and the problem doesn't come up during stress tests (it also happened both with the processor at stock speeds and overclocked). It sounded like a heat issue but I underclocked the graphics card severely and it still persisted (20% underclocked memory and gpu). My only guesses left are either bad memory or pci slot. I can't change the card to a different pci with my board though, so I am currently rotating the memory to see if that might be the cause.

Sorry for such a long post--just thought I would detail the efforts I made to this point.

Thanks!
Wes

could run memtest to eliminate ram as a possible source of error

EDIT: I think I read about needing more NB voltage for 8 gigs of ram. However running memtest should tell you if it's mem related or not. So run memtest for a few passes and see if it finds any errors.

I have run memory tests at startup with no errors found... but I'll try downloading and running that.

What is the voltage on your RAM. Kick it to 2.2V (if not already). Sometimes I forget to up the voltage back to 2.1-2.2 when I restore defaults and I get BSOD's like that.

I think it may be an issue with my motherboard needing a bios update.
I found a forum on evga's site with the exact same issue and that seems to be the general complaint... will keep it posted if this gets resolved.

Memtest passed on all.
