I just reformatted my PC, after installing the OS I already installed Norton Anti-virus. After that my computer restarted and then right after the windows xp (with loading bar below), the monitor turns off. I restarted it for like 3-5 times but same thing happens. What do you think is the problem? Is it the RAM or video card? What will I do? Tnx.. :confused:

Could be a firewall problem. Try switching it off for the short period that you need to re-boot.
