PC works with Linux but not with Win 2000

Hello!

I have wrote about this before and I think I have tried about 20 things.

But I would ask you what you think about this:

I reinstalled windows 2000 and the computer started to hang even more then before. So I gave up, I thought that it must be something wrong with the hardware.

But before I throwed it out the window a tried to install Linux Mandrake 8.0. I really thought I would get the same result, but belive it or not IT RUNS PERFECT.

Can it be something wrong with the windows 2000 cd? The install of windows 2000 vent without any problems. But when I start it it hangs after 1-10 minutes.

What do you think about it?

13 Run with 256 MB Ram borrowed from a friend.
14 Tried to generate the error in safe mode, but PS will not start with less then 256 colors.
15 Run Microsoft Memory Diagnostics (standard and extended test) without any reports of errors.
16 Reseted the bios.
17 Icreased the pageing from 250Mb to 500Mb and the registry from 40Mb to 45Mb.
18 Scaned the disks with chkdsk = 0 bad sectors
19 Scaned with Seagates scan tool and received Result: Failed with critical Errors so I called Seagate and the told me that this was a common message at old harddeives and nothing to worry about. Bad sectors would be something to worry about but that is not the case.
20 Switch the paging file for Windows to an other partition
