Windows install reboot problem

"I agree with Wil's answer, though I expect you won't be able to find much damage by visual inspection.

If the issues are mostly coming from drive accesses, the problem could be confined to the drives or the motherboard's drive controller. I'd try

a) hard drives that were not in this computer when the old PSU blew, and/or
b) using an add-on SATA controller instead of the motherboard's built-in controller.

These tests would eliminate the possibilities that your issue is being caused by a) a damaged drive or b) a damaged onboard SATA controller. If only the onboard SATA controller is causing issues, this might allow you to continue using that motherboard."
