Hi, I always have this "blackout" screen on my laptop for no reason. The drive still makes sound but can't do anything, so I have to force shutdown. It happens during idle when I leave the laptop doing nothing. Sometimes it reboots back by itself. Yesterday, I got a BSOD and the system make one minidump file. I am using WIndows XP Professional version 2002 SP3. CPU is Intel Core 2 T5300 Attach is the debuglog.txt from my minidump file. Hope someone could help detect the problem. Thank you.
