System is having a problem...

[SpeedSlayer]

Here is the system:

P4B-266C
1.8ghz P4
256mb Ram
GF2 Ti
DVD+RW
CDRW
80gb Maxtor

Here is the problem:
I started the comp about a week ago, and an error came up. I restart and all of the sudden the screen with the information says: Memory Error. So, I go to reformat just to see it that would solve anything and I cant install Windows back on. It will reformat, and do everything fine, just can finish the install. Is it a good possibility my memory is causing this?

Test with memtest86. RAM errors aren't good for installing the OS and such.
