OK here's some general troubleshooting tips from a tech support guy:
1) Check inside th computer to see if anything is loose. If so, put it back.
2) Check the temperature of the CPU. 030's and 040's can get incredible hot and your present cooling system may have failed.. ( Dunno about 060's, though )
3) Check all socketed chips and IC's for chip creep.
4) Check your RAM. It can cause more trouble than you think.
5)Finally, if everything else fails, try to remove anything that can be removed. Does it boot? If so, reinstall the disconnected HW piece by piece until the the computer stops working...
Hope that it'll help a bit...
