A while back I built a computer. Here are the specs if they help at all:
Abit NF7-S mobo
Radeon 9600 128
Samsung 80 7200
512 333 DDR samsung
The thing ran fine for a few months, but over the last 2 it started to turn off abruptly, without going through the shutdown sequence (as if someone pulled the chord). The strange thing is, the red light on the mobo stays on but i have to unplug the comp, wait a few seconds, and plug it back in before it will turn on again. At first this would happen every other day, then every few hours, and now I can't even get into windows
I have tried various things to try to solve the problem. I have replaced the psu, hard drive and memory but ran into the same problem all over again. One thing I must note is when i replaced the ram it ran smoothly for a notable amount of time, but in the end started to shut off again. I have set the case to turn off after four seconds of continuous pressing of the button, and my cpu temperature is constantly under 50 degrees.
I suspect that something is faulty in my bios, and I am considering updating it, even though It ran all of the components smoothly in the past. Can I update the bios using the windows cd as a boot disk? or do i need to use floppies?
