I have a eMachines M2350 laptop. I had to install a new HDD and used the recovery CD that came with laptop. It installed Windows XP SP1. When I upgraded to windows XP SP2, the laptop keeps crashing and rebooting. Searching through the internet I discovery that it was a registry entry. The laptop came with a BigFix program that corrected the problem. But, Bigfix is no longer available. I've performed a recovery again, which put me back to SP1. Are there any suggestions to how to resolve the problem
