PC randomly restarting help
Can anyone give me some advice as what could be causing my PC to randomly restart?
Gigabyte GA EX58-UD4 Rev 1.0
Intel i7 920
Corsair PC12800 Ram - 6GB Triple Channel
Nvidia GTX 680
Samsung 840 Evo Pro 128GB
Seagate Momentus 750GB
PSU - Can't remember, I know its a 800w modular PSU. It's fairly recent (18-24 months old) as the last one blew. It's a big brand though.
Case - Zalman Z11
The problem I'm having is, the PC restarts at random intervals. Whether it's just browsing the web, watching videos online or playing games. It isn't regular and doesn't even happen every time I use the PC, but it does happen often enough to be a problem, especially recently as my Fiancée has been studying for an Accountancy Exam and has lost some work.
There are no error messages, no blue screen and no message when booting to say the usual "the PC wasn't shut down correctly...start windows normally", no message once Windows has loaded to say it's recovered from an error.
It's only started happening over the last couple of months, at least 6 or 7 months after I installed my last upgrade (SSD). I can't figure out what the issue is.
I've never come across this issue before, usually when a computer is misbehaving there's usually an error message or blue screen or something to acknowledge that there is a problem.
The components are pretty new with exception of the Mobo, CPU and Ram which I bought 5 or 6 years ago now.
Has anyone come across this problem and found an issue?
Could it be that my Mobo, CPU and or Ram is on it's last legs?
Thanks in advance.
