My old machine was commissioned a week over 5 years ago.
Lately, the hard drive got noisy...bought a DVD burner and a new hard drive.
Other week, the thing wouldn't boot...got it running, and put the new hard ddrive in...worked OK.
Thursday, while my girl was playing Frogger, it went "Beep Beep Beep", and tried to reboot...never even got to Bios.
So went to a local new company, a few young couples started a business assembling PCs and things.
It's an AMD thing, 3GHz or something like that.
