[GRLUG] dead computer

[patrick at upmerchants.com]

Hello,

My computer died this morning.  Over the past week it has been having  
hard lockups where I need to power off and back on to get it to work.

No problem messages of any kind in /var/log/messages or  
/var/log/syslog when I checked it astre restart.

I did get a bios message once, something about the "dram" setting.   
Did not record it so cannot say amy more about it.

Power supply looks good when plugged into a power judge tester.

system consists of:

ECS A780LM-M2 AMD 760G Motherboard - Micro ATX, Socket AM3, AMD 760G

Unfortunately I don't have any other machine / parts to swap around to  
see if it will revive.

Any ideas as to what could be the most likely cause / what parts to  
start replacing first?

Thank you.
