graphics card= lag

when my geforce 6600, pci express installed it causes lag on my computer and games... but some games won't run with out it... what could be the cause for this lag?

 

What games? What resolution? System specs of your computer would be nice, like cpu, memory, etc....os?

sorry... I didn't much help in the search. ok I'm running on windows xp 3.0 dual processor, 1 gig of memory, nvidia geforce 6600 pci express. Now when I dont have the graphics card in the computer runs fvery smoothly (not with highend games) with the card the actual computer performance slows down when I right click the desktop it takes about 2 seconds more, HL2 skips and stutters once and a while just overall it is slower, I'm not sure what the cause of this is I didn't get much out of the other posts either could anyone help?

 

Dual processors as in two core processors or two actual processors?

What are the processors. You said 3.0, so I assume 3 ghz.

Also, what motherboard?

 

its probably a prescott dual core. have u tried disabling fastwrites?

 

how would I do that? I don't think this could be a faulty computer it's just the graphics card, I think its getting interfered by something I'm on a sony vaio.

 

also I heard for some cards direct x 9 won't work on HL2? if not where could I find a patch to make directx9 work?

 

Direct X 9 worked just fine with HL2 on my VAIO (RX-850). HL2 uses STEAM which downloads all needed updates when you start it up.

It was a long load process even on DSL, hate to try it on Dial Up.

 

u can disable Fastwrites in ur Bios or using Riva Tuner
