random restart and bsod

[chad]

ok my computer randomly crashes/restarts, cant figure out
why, ive tried a number of updates, changed the cables in
the comp, tried a different video card, taken out older
parts, reinstalled windows xp 2 times - using a different
disk each time, but it continues to crash, i turned off
auto reboot so that i can read the bsod error messeges,
that three that i have been getting are:
Driver_Irql_not_less_or_equal

Windows system logon process error
and
Page_fault_in_non_page_area

could it be the RAM? is there a way to test it... w/o
having to load a program onto a floppy disk?

Very well could be the RAM. Try running MemTest86.

how long was that test supposed to take? cause it was
going on 3 hours when i exited it, it was onlike test 12
of who knows how many, but it hadnt found any errors so
far. are there any programs in which i can execute them
through xp?

and is there anything else that could be wrong? i dont
suppose it could be the HD?
