Hi, I decided to reformate my HD from 0 Because of bluescreen errors, I have a P4VM800 Board with 512MB DDR 333 ram and a P4 1.7 CPU, the thing is that when I try to install XP SP 2 with a new reformatted HD the installer is giving me a bluescreen. The reasin to reinstall were to get rid of the bluescreen. I was getting random restars and windowws has recovered from a serious error messages... but after a day I could not make the computer start without a blue screen. I have changed the memory module for a new one and have removed the wireless card and modem so the only thing conected to the board are the CPU and HD and CDRom. CPU Fan is clean and working perfect. Any idea? Thank you in advance. Julio.
