Alright, having a huge issue with my desktop system. Attempting to do anything ends up giving me the standard "Delayed Write failed" error followed by not being able to run anything(gives the error not enough system resources...)

Here's the specs on my system:
Motherboard:Gigabyte GA-EP35-DS3P
CPU: P4 3.0ghz Prescott
HSF:Arctic Cooling Freezer 7 Pro
RAM: 2x2048mb DDR2 PC-6400 OCZ SLI Kit
Video Card: Asus EAH3870X2 1GB PCI-E
PSU: PC Power & Cooling Silencer Quad Crossfire 750W
Case: Lian-Li PC60USB
Keyboard:Logitech G15 1st Gen
Mouse: Logitech MX1000
Speakers:Logitech X-540
Monitor:22" LG W2242T LCD
Hard drive:Seagate Barracuda 80gb 7200rpm SATA
WD 500gb 7200rpm SATA2
Optical Drives: LG DVD-RW(20x)
Additional PCI cards:Linksys WMP54G Wifi card,Creative SBLive 5.1
Number of fans present:2x80mm(Zalman),1x80mm Arctic cooling ACF8

It's a fresh install of XP Pro SP2 with all the drivers installed and up to date. The hard drive is brand new and I was having the same problem with the 80gb that XP was on before.
I've tried changing memory slots,memory timings(Running at 5-4-4-15@2.1v exactly as spec'd on the memory) and have run memtest for 4 hours with no errors.
Can't for the life of me figure out why I'm having so many issues with this pc.
Temps are great(CPU-29 idle 45 load,vga-55-60 idle no load yet)
Any help would be greatly appreciated. Thanks

Some updates to the info though- Disabled the RAID driver, Checked the registry for the Largesystemcache(was already set to 0),removed all pci cards and video card and ran a rage128(system worked fine this way) uninstalled all ATI drivers and ran drivercleaner and the sytem is stable with no video card drivers but as soon as I install them everything goes to hell.
Tried 8.9 catalysts and 8.4(the included driver) and both do the same thing, with or without CCC.
Not sure why I always have issues with video cards, about ready to give up on ATI as much as I like them and maybe go for a GTX260 or something.
Any help?
Thanks in advance
