restarting issues on new pc

[tiger64]

recently i built a new computer on septermber this year, and everything is fine, until now the system restarts w/o me telling to, it happens when i was not on the computer, i was at school leaving the computer on at home, and when i got home, i see that everything has been closed and i turned on the local area connection status icon, and see it only has 2 hours on it, so i think the computer has restarted on its own,

any 1 know why this happen , and how to fix it ?

faulty psu maybe? in your sig you say its 400w's, can you give us the full specs?

I run the same config with 430 Thermaltake PSU, and is solid for the last one month /I don't ever turn the comp off/. However, I had plenty of headache with the ram , now I'm on Kingston. Not that yours is bad, just u may have bad module /e.g. static elkectricity damage/. Try first with other memory, it's easier to change than the PSU.

or system ?

Either overheating or malware is my guess.
