Problems?!

[Kunk]

Hi

I have a problem with my computer and dont realy know whats the problem >.<

Ok lets start with my setup:

9800GTX+ Asus 512mb.
Xion 500W Power supply
Intel Core2 Duo E6850 3.0 Ghz
2x 80gb Samsung spinpoint
Xfx nForce Motherboard 680i LT SLI
Windows Vista Buisness 32-Bit
4gb OCZ PC6400 CL 5

I update my drivers and my system everyday if there is something to download. And i defrag my disks 3-5 times a week. The problem is that i got some lagg in games like Warhammer. And low fps in World of warcraft when i use vista. Its around 70-80fps and in xp 150-180fps :O Sounds wierd right? I had some problems with the memory befor and then i removed SLI Memory function and updated BIOS then i dident get any errors in memtest. had like 9000 errors when i had SLI on and old BIOS. Even my sound can lagg sometimes when the cpu use goes up to 100%.

I think this is very wierd and i have read alot of this on internet but havent found any solutions. Anyone here know what can be the problem? The disks is like 5 years old, can it be that or what is it? Hope anyone know the problem. Thanks!

Maby dident say what was the problem Its much Delays and my computer dont do as much as it should. I mean it should get more fps then my old 8600gts. It has to be some problem any were. My sound lagg when i use 100% of my CPU and such. Let me just say its lazy. Is there any programs that can scan your hardware? So i know if any part is broken.

THanks // Kunk

Vista is slower than XP, and the 680i chipsets have lots of problems that were never fixed. You might consider upgrading to a MB based on an Intel chipset.

PS - Maybe you haven't turned off background file indexing in Vista?
