Well, regardless of what games, my computer will just freezes up for no reason. I had been changing display drivers for my Geforce 8800GTX but to no avail. I'm suspecting that all the causes of system instability is the display driver. But well, I better let the experts take a look. I had just faced a IRQL Not Less Or Equal Error.. with the following code. 0x1000000a (0xd9c45e9d, 0x0000001c, 0x00000000, 0x80502381) I'm also attaching a minidump. Please help me. Thanks.
