Question : Problem: Many white lines on screen

Hi Experts,

I've a erratic problem for my PC of 4-6 mths. It's a dual core 2.4GHz PC with Windows Vista. The symptoms varies. Sometimes the PC is ok for some time(from a few mins to a few hours) and then the problem will come. On most occasions, many white lines will appear on the screen. The many white lines continues to appear even after a reboot and appears even at the BIOS screen. On a few other occasions, the PC suddenly reboots by itself. Also on a few occasion, the blue screen appears saying critical failure and forces a reboot.

I am suspecting that my PC is overheating. I activated the ASUS PC Probe and it shows my CPU temperature varies from 43-50 degrees Celsius(most of the time i see it at 46-48). System temperature is around 37-42 degrees Celsius.

I am not sure what is wrong. Can someone advise?
