I built this PC about 2 weeks ago and have had no problems playing the graphic intensive games i built it for. When I beat all the games I couldn't play before I went back to some of my old favs and this is what's happening. first off my machine has a

Athlon64 x2 5000
Asus M2N-SLI board with nforce 560 sli chipset
4 gigs of samsung ddr2 800 ram
one Evga geforce 9600gt with 512 ddr3 ram
running windows xp pro 64-bit
all powered by a 650W supply

Now i've been playing games such as test drive unlimited and NFS pro street or supreme commander fine, and still they run great with no problems. when i try to play games such as half-life 2 on steam, or UT2004 the game runs fine in menus but about 30 seconds into gameplay my monitors turn off the sound glitches into a loop and nothing responds till i reset the machine. All my drivers are as up to date as i can find, and i've looked. my hardware monitors show no spikes in voltages up or down, and heat is running within optimal temp. I may be leaning toward the onboard 7.1 surround because elder scrolls oblivion runs fine graphic wise at max but my audio is completely fubar. The only way to describe it is it sounds like holding a TV remote up to a guitar pickup. I have not overclocked anything since i'm running higher end games without a hitch i'm really at a loss. Anyone have any ideas?

see if this can help

Nope, did however lead me to a missing boot.ini file, I even bought a sound blaster Fatal1ty to replace the onboard audio, disabled the onboard audio and still no improvement, it actually crashes almost immediately after gameplay starts now, and my physical kernel page memory shoot from 84mb to 150 almost instantly after gameplay starts. and boom, have to restart again.

maybe run in compatibility mode downward to win 2k or win 95. also try decreasing graphics acceleration and/or audio acceleration.

Nope, That has not worked either, I've done some adjustments in my system. First I Changed my ram and took my 2 2 gig chips out, and intalled 4 new 2 gig chips, I've wiped my system clean and tried a 32 bit os, still the same. I disabled my onboard audio in bios and bought a soundblaster X-Fi Fatal1ty Pro Xtremegamer and still did it. PLus all the problems i had to work out with that stupid card, still can't get 5.1 out of it but that another issue. Now I have yet again Wiped my drive clean and installed Vista 64-bit, it takes about 2 min to lock up rather than 10 seconds. I've run a series of stress tests on video card and it runs like a champ and benchmarks at 497 fps, and still it is only my shooter games that seem to do this, UT, UT2004, Halo, and Half-Life 2 deathmatch on Steam. I'm at my wits end with this and have already burned a large whole in my pocket trying to get this machine to work like it should, I'm starting to wonder if my loyalties to AMD and Nvidia are not well placed. I still remain confident that I'm just missing something, but as to what i'm out of ideas, heck i've even underclocked everything i have as much as i could just to see if that would make a difference, shot in the dark i know but i'm clueless right now. Heat is fine, ran diag utilities on my video GPU and CPU heat, Kernel Memory seems to be freeing up as it should. 8 gigs of DDR 2 ram so that never comes close to filling up, tried single sticks of ram at a time to see if maybe a bad ram stick, AAAAGGGG, much more of this and i'm ebaying this thing.

tried rolling back the video drivers like uninstall and install earlier version? i have a problem with an older game on later components but for me older versions make it worse. i think some older games simply won't play on new components.

Used the earliest version of drivers i could find, and still crashes. and i can add a new game to the list of WTF. AVP 2 does the same.

1 last thing to try.
displsy properties, settings, advanced, toubleshoot. reduce graphics acceleration.

Still locking up, OK i've calmed myself a little, I'm pretty much figuring that my board can't handle my card, the 560 chipset is pretty old in computer years, but it's been a long time since i've tried to stay current, what is the 2 top end chipsets supporting SLI tech?

i've not gotten into sli on amd boards so hopefully someone with more amd experience will come along.

Hi all
I been looking for a fix for the same thing. ive found 1 but i aint happy with it. i got 3.5 gig of ram and i get the complete lockup thing too when playing nfs pro street. i pull 2 sticks any ones and take the system down to 2 gig all games run fine. when more than 2 gig hits the games they lock up. nfs is the worst enemy territory quake wars is another. i was thinking virtual mem or something is set wrong ive been into the bios a thousand times its not that change sound cards graphics cards more power. reformated . only fix is take out 2 gig and run at 2. but im not happy about doing that so ile find another fix. try it and if it works for you let me know. good luck.
