PC randomly freeze

[aioxen]

Hye.
I have a problem with my windows.
It randomly freeze, usually right after startup. It has no blue screen whatsoever. I usually need to do hard reset 2-3 times before my sytem stabilise.
I thought it's because of my hard disk, so I bought an SSD yesterday and have installed windows in it.
I thought it solve the problem until tonight my pc hangs again twice.
I still use the old hard disk as storage. It should not cause the windows to freeze, should it?

I'm running windows 7 64 bit.
I have updated the bios today. problem still occur.
One thing i notice is my CPU temp is ~60 degree at idle which is too hot. is this the cause of the problem? but the temperature has been that for like 6 months, where the freezing only starting to occur at recent weeks.

Can you guys help me solve this problem. thanks

CPU is WAY too hot for idle.

Check heatsink is on correctly and fan is working. Should be in the 30s idle.

You've slow cooked your CPU. Just because it worked for months at that temperature, it doesn't mean you can carry on doing that without problems.

I shudder to think how hot it got under load if it's idling at 60.

You've probably killed the CPU, which is bad. On the good side, it's a rubbish CPU anyway, treat yourself to a new, better one.

I am waiting for my new CPU. we'll see how it goes
