what does this blue screen mean?

[blackinches]

i got a blue screen on windows xp. what does it mean when it says irql not less or equal? it only happens when i play games. so i'm assuming it has something to do with my vid card?

Generally means system unstable, possible RAM problems.

If your system is overclocked, put it back to stock speed. Back off on the RAM timings to SPD and see what happens.
