I've got problem. I'm using old KBS-MX motherboard and feel 300ATX powersupply. Sometimes when I'm doing something, sometimes I hear sound in my loudspeaker like it got plugged off of computer and my computer stops. I can't do anything even mouse and keyboard is not working everything stops. Do you know what could be the problem?

PS: I've got the newest linux.

by "I've got the newest linux" ... what do you mean? Which distribution? What release? – warren Jan 25 '11 at 2:24

Well ... first, check the logs (/var/log/...)
Second I would suspect the power supply. Does this happen when your computer is more stressed?
Third there may be some problems with the RAM.
And finally I would check for CPU overheating.
