Late last week it stared to lockup after 4 or 5 hours, sometimes wouldn't even boot.
I'd been thinking of upgrading its Fedora from v9 to something a bit more modern for quite a while but never got round to it. All this locking persuaded me to give it a go and maybe it would solve the locking.
On went Fedora 14 and the locks continued

hmmn :evil:
ok, I'll borrow some memory sticks from work and see if it's my memory sticks at fault.
Nope, it still locks up.
So yesterday I removed the CPU and heatsink, cleaned them both up and refitted them with new paste and so far so good, it's been up for almost 24hrs now :thumbup:
Strange thing is that the CPU temperature monitors weren't showing anything unusual and it didn't seem to make any difference if boinc was running or not.
Maybe CPU paste just gets old
