hello everyone,
I've just bought VS2GSDS667D2 for my toshiba tecra a8 (C2D T5500, intel 945 chipset). I installed new memory next to old one (samsung 512MB 533Mhz). Unfortunately this configuration didn't work well, linux get slow and windows xp didn't boot at all. So I removed old 512MB ram and left only new one. After that linux works very fine, however win xp still don't want to start. Windows just reboots machine after 2-3 seconds of loading

BIOS recognizes all 2048MB of ram. I did memtest twice and it didn't find any bug. Windows has SP2 and all recent patches. What might be a problem?
I would appreciate quick anwser, as I need to do some work on windows this weekend.
