Thread: Computer has been crashing a lot

my desktop pc running ubuntu 10.04 64bit, has been locking lot , has been needing frequent hard resets. it's irritating. there way diagnose causing system crash that?

alt-prtscrn-reisub trick doesn't work, let alone ctrl-alt-f1 or anything. it's locked solid, 100% unresponsive except power/reset button.

thanks,

this many things , suspect hardware issue. first thing should boot live ubuntu cd , run memtest check ram. let memtest run through test @ least twice ensure thorough check. if ram clean without error should check hard drive problems.
boot again live cd , open terminal.

code:

sudo e2fsck -n -f

force check not make corrections. important not mount drive before or during check. let test run. if errors show ,start , run terminal again

code:

sudo e2fsck -p

attempt correct drive error. if run both tests , nothing shows up, may need have power supply checked technician.
