Hi guys,
I'm not really a "newbie" to this forum.... but leaved for a while, and now I had to register myself again.

Let's go right to the point.
I recently changed case, switching form a Chieftec big-tower case w/ 320W PS to a smaller, midi-tower case w/ 400W PS, aluminium made.
The cooling solution changed also: I switched from water-cooling, back to raw-air cooling :( ... due to space limitations.

Right now, everything is runnning fine, EXCEPT for any 3D application (such as games...) I try to run.
Infact, after a variable amount of time (randomly ranging from 2, up to 30+ minutes...) any game suddenly quits back to windows w/o reporting ANY error.
Even games such as Sim City 4 (which is not actually a "3D-intensive" application) suddenly quit back to windows after a variable amount of time... :confused:

I tried to change CPU, with two different "flavours", w/o effect.
I changed PS, with one less powerful (380W) but made with better components (I suppose and hope...), only to find out that every game, now, quits after a bigger amount of time... but still quits!... :mad:

I thought about several possible reasons:
- temperature: the case is smaller and worse ventilated than the previous one and the vid card and/or CPU reaches too high temps, but if so, why games quit after a "random" amount of time?
- electric: the M/B discharges somewhere/somehow, but why not everytime?

Before I rip-open the whole PC looking for a better answer, does anybody out there had the same symptoms and, possibly, solved 'em?

Here is the current config:
Asus A7N8X Deluxe (latest BIOS/Revision)
AMD Barton XP 3200+ (tried 3000+ and 2200+)
1024Mb DDR400 (512 x2, no-brand), single channel
Sapphire R9700 Pro 128Mb
Quantum Atlas 10kIII, 36Gb 10k RPM U-SCSI 160 + Adaptec 19160 U-SCSI 160
2x Maxtor D.MaxPlus S-ATA 160Gb in RAID 1

Thanks a lot
 
Did you try video drivers?

Test using several variations, first latest cats, then go down from there try 3 or 4 different ones. Worth a shot.
 
Tried all Catalyst from 3.5 up to 4.5....
... and I'm using DirectX 9.0b....

The curious thing is that everything started when I changed case.... that's why I think about an electrical/mechanical problem, rather than a software problem.... :confused: :(

Ok, I know what's next: somebody may argue that switching back to the older case would solve the problem. But what would be the point in doing this?
I want THIS case to work!....
 
Wow, have you tried reseating everything? Also, try to look closely and see what is causing these crashes.

IOW, yes, you may have to rip open your PC :(
 
This evening I'll take out the whole system and try to run in free-air for a while... just to see if it's the case that fools me.

Oh man, I hoped to avoid this.... but I'm forced to! :mad:
 
Before starting to warm up the jigsaw, I decided to take a chance and try a good old method of mine.
I removed the wireless LAN card... I fogot to mention that particular piece in the configuration...
Well: I played "Colin 4" for almost 3 hours without a problem!.... since it crashed.
But then, windows reported an error (finally!)... genereted, apparently, by the video card driver....

I'll keep on testing....
