System specs:
Asus NForce4 A8NSLI-Deluxe Mobo
Athlon 64 3500+
Asus 6600GT 128MB PCI-e Video card (just one, running in non-sli mode)
1GB Kingston DDR3200 (2 dimms)
160GB HD
Windows XP Pro-SP2
17" KDS CRT

What works:
Dxdiag Direct Draw (2D) works fine
Some basic games i assume do not require 3D acceleration runs fine
Basic computer functionality is fine (word processing, chatting, internet)

What doesn't:
Doom 3 and Spellforce (massive polygon flickering... hard to describe it other than constant black polygon flickering across the screen, depending on where i look, it changes)
.avi and .ogm video files. They play... sorta... the sound comes out, the display either locks into one of the initial images and flickers, or just shows garbage. Tried WM player and VLC Media Player, same result
Direct 3D (through DXdiag), the "spinning cube" flickers randomly and only looks vagueling like what it should (somewhat looks like it's spinning ultra ultra fast, or it's not really spinning at all and it just flickers, depends on how you look at it)

Here's the situation. Built the computer back in February. Worked fine for a couple months. Then one day, come back, display is black, computer running, can't get it to come back. Restart computer, get "system failed VGA test" boot error, so it doesn't boot. RMA the 6600GT and get a new one back. Install it, runs fine. Run some video files i moved off my laptop, they work fine, then suddenly around the 10th file or so (.avi) the video suddenly scrambles and hasn't worked since. Ignored it for the time being, tried to play some DOOM3, and it's got problems. That's when i realize something's up. Tried other things, troubleshooting, didn't work.

What i've tried:
installed new detonator drivers from nvidia website
installed omega drivers to see if those work
tried to update DirectX 9.0c (but i already had it, so it didn't change anything)
changed resolutions and game settings
Yelled loudly and beat my desk a few times

Help?

Forgot to mention, i haven't done any overclocking, cpu temps seem to be fine, no real extra fans except one extra one on the side of my case (default CPU fan, one mini mobo fan, and of course the 6600Gt has a fan attached to it and the PSU fan). Haven't done any real benchmarking yet, because i don't have any good benchmark utilities...

noticing a new anomaly now...

Periodically (say... once every 15 minutes, with 30 minutes being the longest between occurances and 30 seconds being the shortest) while just browsing the internet (playing flash games) my screen will freeze for... 5 seconds. I believe my entire cpu freezes as well because the performance graph in the task manager doesn't seem to update while it's frozen. Then the monitor (CRT) will flash (as if it were changing resolution) and then come back and be back to normal. What in the world is going on???

Oh, and i want to flash new bios, because i'm using the one that came with the board... which probably is bad. Don't have a floppy drive, anyone have some good instructions on what to do?

Add one to the insanity... Probably more than half the time when i run video files (avi, ogm) they will open the media player (WMP or vlc), sound comes out, either no display, a shaking freeze frame of one of the opening scenes, or garbage shows up. Then i can try to close it, but aside from my mouse, nothing will work... it'll sit like that with the sound coming out of my speakers for about 30 seconds, then my computer shuts off and restarts... not good... not good at all...

that sux man.. i'm thinking of getting the asus 6600gt too so you're scaring me ;p

did you fix your problem? shame on you for not getting a floppy drive on your new rig !! Why don't you just go buy one for 5-10$ at your local computer store and that'll solve your problem of flashing your bios. there may be other ways but I don't know of them.

let us know if you fix it though. I'd like to know how if you do.

I got the ASUS N6600GT, works fine as far as I can tell.

Did you install Omega drivers to see if they work? Those are for ATi cards. Driver Cleaner-remove them.
