Windows 10: PC randomly restarting / shutting down repeatedly. No bluescreen this time

I'm running into a weird problem. My PC is randomly powering down and then booting again on it's own. I'm not getting any bluescreen errors or anything it just goes black, shuts down, boots back up a second or two later. So far it's only happened after signing into windows and using the PC for a bit. I tried not doing anything and letting it just sit after signing in vs opening programs etc. and it reboots either way. Sometimes it stays on longer than other times before this happens. I've also tried unplugging pretty much all my USB's and anything else that was connected except for my keyboard

Random shut down and restart??

Computer: Intel (R) Pentium (R) Dual cpu
E220@2.406hz
2.42 GHZ, 2.00 GB of RAM
Windows xp

Ever since I replaced the fan (with heat sink) the computer has randomly shut down and then restarted, at first during streaming, and now, will shut down and restart anytime. I tried to replace the graphics card to no avail. *Confused *Mad

One suggestion was to replace the RAM.

Any suggestions on how to repair my computer?

PC randomly shuts down.


Ones pointed out on PSU voltage seem a bit low, temps on System seem o.k.. Did not go down to the Graphics card. When this shuts down randomly it never restarts right away or does it do it while using the PC ?
