I've been having lockups during different games getting the looping sound lockup. I have all of my drivers up to date, and nothing overclocked. Memtest86 ran for 5hours and no ram errors found. I found that disabling write combining in nvidia options seems to have fixed my problem. My only problem now, is that it seems I have taken a performance hit. I get lower fps in games and my Aquamark scores are 10k lower. Is there anything I can do to bring my performance back up to par, or something else I can try to stop the looping sound lockup. My system specs:

Gigabyte GA-K8NSC-939 Nforce3 chipset
AMD 3500+
Nvidia 6800 Ultra
2gig 4 x 512mb XMS Corsair
2 SATA Hd's
Coolmaster 550W Powersupply
Windows XP SP2

Aquamark03 67K before disabling write combining
55K after disabling write combining

Thx.

Do you have fast writes enabled, you could try playing around with that with write combining enabled/disabled.

Its also worth turning off all bios shadowing in the bios.

I don't have an option that I see to turn off fast writes in my bios. I do see a shadowing option, I'll try playing with that.
