I've been posting over in the BSOD forums, and I've downloaded CPUID Hardware monitor in a bid to find out what exactly is wrong. Only thing is, I am not certain what I should be looking out for, so I've attached the monitoring data file to this post if anyone is able to help me make heads or tail of it. My hardware setup: ASUSTeK Computer INC. M4A78LT-M-LE AMD Athlon II X4 640 Nvidia GeForce GT 240 Memory 4.00GB Microsoft Windows 7 Ultimate 64-bit 7601 Multiprocessor Free Service Pack 1 I notice that the idle temperature for the graphics card is holding at 53 at the moment (it has a 105 degrees maximum under load). On Sunday I plan to run a series of tests to ascertain what happens prior to BSOD events as regards hardware performance, since the last three weeks none have happened - they all started in Windows, but seem to be more likely in games (add to that, they magically started after weeks of smooth running of said games). Replaced harddrive because that failed all the manufacturer tests, and the issue had been fixed...then came right back (obviously it wasn't the harddrive causing it ). I have kept off games for a bit because I rely on my brother to assist in fixing problems, and he's been away (if anything goes wrong, who do I have to blame?).
