I have an old Dell I bought in 2001, and I have just started having some weird problems. When I boot up the system it states system memory has decreased some hex values press F1 to continue F2 to go to set up. In setup my 1024 MBs of RAM shows as 964 (or something similar) and the other problem is I can load any version of linux or Win2K without issues, but WinXP will not load (even fresh) without blue screening.
