when the screen becomes blank and then reappears at somepoints its
totally goes blank but the game is still runin but no display after
some time it hangs
but sometime it hangs with no above occourences any time in the game

IRQ_NOT_LESS_OR_EQUAL
Sometimes when i start my pc it detects the ram at 266 MHz instead of
400 Mhz

im using windows xp with sp2

If the video card has a fan check that it's working.

Test your memory with memtest86 for a couple of hours, this is the
best memory test to use and any errors found will be causing
system instability. If you get errors with both sticks installed,
try them one at a time and in different slots, you may find one is
bad or one slot has gone bad on the mobo.

At microsofts webpage it mentions this as having to do with ATI video cards.
I know your's isn't ATI,but it could be the overclock.
There's other causes listed there but this one seems to be closest.
Also, I seem to remember this same error pooping up more after SP2 was
released.
