Hi guys, my specs are:
CPU: QuadCore Intel Core 2 Quad Q9550, 2833 MHz
Mobo: MSI P7N SLI Platinum/Zilent (MS-7380)
RAM: 4GB Kit Corsair XMS2 DHX CM2X2048-6400C4DHX
GPU: ATI Radeon HD 4870X2
HDD : Seagate 500GB 32MB buffer
Chasis: Thermaltake Armor Plus
CPU fan: Mugen 2
PSU: Thermaltake Tough Power 750W

Lately, my computer have been freezing and forcing me to hard reboot it.
It happened mainly while playing WoW, but it would also pop up quite often while watching a TV show or a movie. It didn't matter if i used the heavy spash pro or the MPC-HC. Both would crash around once in 10-15 mins.
In WoW the crashes were random, it could run for 2-3 hours until it crash or even 12-13 mins.
Crashes sometimes came while browsing the internet (FF Beta4).

This (obviously) drove me bloody insane, specially since it went on for weeks. I tried to troubleshoot the problem. At first i though it was my CPU overcooling. So i swaped the stupid-but-oh-so-cool Thermatake BlueOrb with the Mugen 2, and droped from 68-72 degrees at load to roughly 55-60. That didn't help.
I Though it might be the GPU, so i blasted it with the stock cooling cooling. The temp during freezing wouldn't exceed 70 degrees (which is really low for this card) and it'd still crash. (A GPUZ log in excel format can be found here)
So, as a last resort i've put a room fan instead of one of the chasis' walls and blast the whole computer with all the cold air i could gather. That helped.
Instead of dying completely and utterly, it nearly freezes, waits for me to hit the magic windows trio and it comes back on, reporting the graphic driver has died and a new one has been brought for my amusement. (GPUZ log)

I've tried running a double loop of 3DMark Vantage without it crashing, so I'm thinking that maybe it's not the card. Also, why running the card's cooling at 50%+ wouldn't help? The temp is really low that way.
Which what leads me to thinking it's the mobo's chipset overheating. But i have to idea how to take it's temp in such a way I'll have a log after the crash has forced me to reboot and lose everything.

Hope i haven't left anything out, please help me solve this.

Run Memtest 86+.
Try a different video card.
Perhaps a fresh Windows install?

Memtest was run, all's well.
Windows was reinstalled, tried bother another win7 install and a XP, problem persists.

I don't have anywhere i could get another GPU, i'm kinda poor and friendless :(
(If it is the GPU, i'll pick a new one up, but i can't afford to get one just for testing)

My computer had basically the same issue - but mine turns out to be bad memory, per Memtest86. Only other thing that comes to mind (that isn't hardware related) when you say "WoW lockup" is your video card drivers; it's been my experience that Blizzard seems to require having the latest drivers installed or else my computer experienced the same thing as you - not knowing *when* it'll freeze, just that it *will* eventually.

All drivers are up to date (also tried a rollback though), and the problem isn't exclusive to WoW.

I'd definitely try swapping out the GPU (even with a cheap 5450 or GT 240) since you say that the video drivers are crashing and you've already tried, uh, supplemental cooling on the card.

Even if it turns out not to be the GPU, it's always good to have spare parts on hand.

Or try asking in your local computer store if they have a cheap card on hand you can borrow. I have done this a couple of times.

bump + update.

After roughly 6 hours with the 4670 I've extracted from my gf's computer, and putting my comp thru things that made it instantly crash yesterday i can confidently say it's the GPU :\

What i don't understand is: If it's an overheating issue (big ass fan turned complete freeze into driver crash), why did it happen when i told the card's fan 'go wild' - at which point the card was cold..?

you're assuming that a video card can only fail due to heat issues.... bad assumption...

may be due to a bad connection/solder point somewhere..

I wasn't able to reach a proper crash with better cooling, no matter how hard i tried. Just driver fails.

Ive had ATI give lovely hard locks before and it was strictly driver related. NEWEST driver installed, hard lock every couple of hours. Year and a half old driver? Rock stable, no locks... ever. I've not generally had a good experience with ATI on the driver front, and this is no exception. I was astounded that the driver that came out THIS MONTH would hard lock the machine... the driver that came out in october of last year... hard locks the machine... back date it to the end of 2009 (september maybe?), rock stable.

Ridiculous. So I dont find this surprising behavior for an ATI card/driver.
