Dear News Readers

I'd like to ask your recommendation for the following matter.

I have a computer, which I used for 3 months with Window XP without a
big problem. But, recently, I felt the computer showed a blue screen
and downed too frequently. So I installed Fedora Core to that
computer.

That computer was OK for several days with Fedora Core, but it downed
more often than Window XP when I use X window. To avoid the breakdown,
I used that computer only as ssh-server. I mean I do 'ssh' to that
computer, and run some program which does not require X window. But it
was OK just for several minutes, and stop running the program after
sending some message something like "...Bad RIP on value". In this
time there was no system down.

After frustrated by these problems, I decided to change back to Window
XP. But, in this time, the computer did not allow the installation by
sending the message like "...IRQL not less or equal...".

Now I also failed to install Fedora Core.

I googled this matter, and some people said those message("...Bad RIP
on value" or "...IRQL not less or equal...") are related to false ram
or socket.

Could you guess where the problem is ?

Thanks in advance
