i have a custom built system which is over 6 years old and is running windows XP Pro service pack 3.
the problem it is having is after startup it will loose the display after about 40 seconds but doesn't turn off also it will click (not HDD Clicking) click sounds like it is coming from the motherboard and you have to force a restart. I have tried new ram, PSU, DVD drive and i have removed everything but the HDD, power switch, PSU this seemed to have worked as it stayed on for a few hours, i tracked it down to a network card that caused it to loose the display.
While i was testing it (about 40 min) i started a sfc scan while the scan was running the problem happend again and i had to force a restart, i also have turned off all startup programs and non microsoft services. i have checked the temp of the system and it is between 31-39 degrees.
here is the model of motherboard i have:
Any help would be greatly appreciated
