Hello, To start, I've attached a .bmp with some information on my Lenovo Thinkpad T60p laptop. Information is taken from PC Wizard. Recently a lot of blue screens have been coming up with the same message, stating IRQL_NOT_LESS_OR_EQUAL. Usually it occurs when I try to watch a video or play a game. However, yesterday I got the same bluescreen while I picked it up from my desk to carry it elsewhere. I've ran PC Wizard in the background to check temperatures and processor activity. Just before a crash, the temperature of the processors would be around 70 degrees Celsius and the activity is irregularly high with both processors at around 80%. If i started the video or game, it would crash quite quickly, in the order of minutes. I've flicked through some topics on this forum and most of you suggested I should run memtest to see if my RAM is broken. I have two sticks of 1 GB ram, I am not allowed to open my laptop because of warranty issues with the university where I bought the laptop from, so I could not test the RAMs separately. I ran the test overnight and got 11 passes with no errors. I think the system could be overheating as I had some troubles with the fan in the past as well, could anyone care to help me with this problem? Many thanks in advance. I've added a .zip file with the last 5 minidumps.
