My homebuilt PC has worked perfectly for several years, but has just started crashing.

It just shut down (no blue screen or other warning) and then attempted to restart several times until I shut down the power. The restarts lasted a few seconds, then another restart, and so on.

A few hours later I tried to restart it, and it seemed to work fine again in normal mood (it first asked to be started in safe mood). After 20-30 minutes it crashed again and started restart.

I have tried it several times, and It seem to be able to work for short periods with a resting time in between. All components seem to work well, and there is no burnt smell.

Any ideas on what to do?

Hi

Specification would be useful

look at capacitors on motherboard especially those near CPU
Bulging or leaking capacitors mean get a new motherboard or if a very expensive one change capacitors ( needs an experience in soldering)

Above link Details full test procedure to confirm problem is CPU or motherboard

Run Chkdisk. (The symptoms you describe make it a must do.)

But first...

1. ABSOLUTELY!!!! Backup all important Data and settings in case ur Hard Drive fails completely.

2. Run Chkdisk on C drive and then all other drives.
(Go to Youtube and watch vids for "Chkdisk" and the Operating System u have. Like: https://www.youtube.com/watch?v=Vf2tBaqav2U )

Another suggestion - did you recently perform any Windows or driver updates? Those can have unusual symptoms, especially driver updates.

Also, is the computer plugged directly into the wall? Random shutdowns could indicate a power problem. If it's plugged into a surge protector, try swapping it out or just plugging your computer into the wall.

Check your power supply, if you have another one try swapping it out. I had this same exact problem, was playing a game and my computer randomly shut down no warning or anything. After trying to reboot it, it would flash on and off rapidly untill I unplugged or hit the power switch on the back.

Think mine went bad due to a bad power source it was only three months old. Its starting to act up again but I at least have it on a surge protector now.
