Ok, the deal is, during a game of Battle field 2 or 2142, my pc locks and a loop of loud screeching comes from the speakers. i have tried new driver, for both sound and video with no luck, also tried different video cards, on-board sound with no luck as well. started with a 430w power supply, i have moved up to a BFG 650w and there seems to be some improvment in the amount the machine locks, but still has yet to fix the issue. Can play 2 hours and then locks, reboot and play an hour and locks, and after rebooting, it locks sooner and sooner.

Any ideas?

sounds like ur wideo card is overheating. or is clocked too high. try out atitool to check temps and clocks. see how high the temperature can go if you leave the 'carpet cube' running for a few minutes. and get back with the results. the 6800s were heat monsters.

that ATI tool doesn't work, just gives me the Send or not to send error report

which version are you using?

i had the exact same problem, cept with xfx 7600gt. i had clocked mine, so i set it back to default, and no results. i got fed up so i sold it to someone else.

the ati tool 0.27b1

i turned down the Core clock freaquency from default 350 to 300 and will see how that goes. im getting a 7900 soon, so maybe that will help the issue

u should use atitool 0.26. its the latest stable version and works better with windows xp and nvidia cards.

after running the ati tools, the temp gets up to 104ºC an the clocks are 391.00 Mhz.
for the core and the mem. is 570.75 Mhz

I had the exact same problem as you. I tried everything, but nothing worked. Then I figured that I'd update my motherboard's BIOS and guess what... it did the trick! Make sure your BIOS is fully updated by checking your mobo's website.

I wish my lawn was emo so it would cut itself.

tried the BIOS update, and no change

jesus. 104C??! thats crazy....u should cool that baby down. i know the 6800s ran hot but thats excessive. that kinda temps could start damaging the chip. it probably is overheating.

but then why with a different video card, would it still give the same issue?

what is the other video card you tried?

nvidia 7300, wasnt the best, just went out and got a card to test with.

im surpirsed u could play battlefield at all with the 7300.ur 6800gt would rock that. does your case have sufficient cooling and airflow? still think the bugger is overheating.
