  • If your computer keeps crashing after a recovery then it is probably the motherboard that has gone bad.

  • If the Operating System will not load then reseat RAM. If multiple SIMMS (Single Inline Memory Modules) or DIMMS (Dual Inline Memory Modules) are present then remove them all and test each module individually.
