MB dfi LP LT P35
CPU intel core 2 duo e8400 @ 3.00GHz (oc'ed at 3600)
MEMORY geil 2GB ddr2 PC2-6400 (2 x 1024 ) dual channel at 800mhz, timings 4-4-4-12
GRAPHICS gainward nvidia geforce gt 240 1024 ddr5 golden sample
OS win xp professional sp3 32 bit.
The sistem is really stable, ran orthos for about 3 days and video card stability test for more than a day.
I bought and installed another 1 gb of geil ddr2 pc2-6400 (2 x 512) dual channel ram at 800 mhz, timings 4-4-4-12, so now i have 3gb(2x1024 + 2x512) of geil dual channel ram at 800 mhz, and xp starts with a lot of weird stripes and graphic artifacts on the screen, the mouse pointer becomes a pixelated square and the video card failed the first stability test I put it up to in less than 3 seconds.
Xp only sees 2.75 of ram, but that doesn't bother me, it's probably because of the 1024mb ddr5 on the graphics card, and PCI audio card.
I dont get any artifacts at all if:
- i uninstall the nvidia drivers
- i start windows xp in safe mode(with nvidia drivers installed)
- i start xp with nvidia drivers installed and only 2500mb of ram(2x1024 + 512) dual channel at 800 mhz
- i change my video card to a nvidia geforce e6600 256mb (with nvidia drivers installed and 3gb of dual channel ram at 800mhz)
- i keep only 2gb dual channel geil ram at 800 mhz and add 1x or 2x corsair value select 2gb dual channel ddr2 at 667 (so with 4gb or 6gb of dual channel memory at 667mhz) and the gt 240
I installed windows 7 ultimate 32 bit and it has the same behavior, only that when i try to start it with the gt 240 and 3 gb of ram installed, instead of showing all the strange artifacts after loading windows, the screen just remains black.
I think it is some sort of conflict between the geil 3gb dual channel ram and the gt 240 which happens on the 32bit win 7 and xp after the nvidia drivers are installed.
I'm trying to figure this out but i can't really put my finger on it so please help me out.

I have the same problem.
I dont believe it has anything to do with the RAM. I think the RAM is that way because you have a 32 bit system, it can only accept up to 2.75 or 3 Gigs of RAM.
I have narrowed it down to BIOS for mobo, bios for video card, or video card driver conflict with Bios, or uncleared previous video drivers.
I have been allover the internet and have found zero solutions, although many people have had this problem.
Common factors seem to be video card that have GPU.
Any help here would be appreciated.
