Hi all, I recently upgraded my Inspiron 1545 to windows 7 which worked fine for approx. two weeks. What happened is blue/white lines appeared across the screen and the computer froze so I restarted it. When I restarted it I found that windows would not load so reseated the memory and hard drive as it suggested. This did not solve the problem. I now get to the the password protected login page before the lines reappear. This takes me to a blue error screen with code, 0x000000024 (0x00000000001904FB, 0xFFFFF8800420B628, 0xFFFFF8800420AE80, 0xFFFFF8000C1ED90D). Any one have any ideas what what could be the problem?
