Running a p4 1.8ghz 478 socket in an asus p4s333. Ran fine for 4 or 5 months then started crashing with nice multicolored vertical lines on screen. Upon rebooting most times, mobo reports cpu failed. After a few resets, problem seems to be gone and computer boots, many times only to crash again with the nice vertical lines upon windows boot logo. Uptimes vary from a day to less than 15 seconds. Replacing video card didn't help. Checked all connections w/ power and cpu/ram. Have sent message to asus hoping to recieve a response soon. Any ideas would be generously recieved.
