My machine started freezing (no blue screens, no warnings) after about 30 minutes to two hours of use after a bad lightning storm that also knocked out my router. I've replaced the motherboard, RAM, video card, and CPU after testing out my main OS drive on another machine for a weekend. The new machine will still lock up, though much less frequently, usually lasting between 8 and 24 hours before dying. I'm totally at a loss to explain this behavior, or figure out what I should try troubleshooting to fix the problem.
Here's what I haven't replaced: Power supply SATA cables to drives DVD drive (currently disconnected anyway) Computer case Hard drives (one SSD, two disk drives)
Any ideas on what the most likely culprit is, and how I might test it out? The fact that it takes longer to seize up after replacing everything is pretty baffling to me.
Thanks for any help!
Edit Some more detail if you're curious why I was replacing other hardware before the power supply... after the storm, the main drive was not recognized as a boot drive by the BIOS even though it worked fine in another machine (and I could even boot off the drive when using the Ultimate Boot CD for Windows), leading me to believe that something on the motherboard got hit. I'll try replacing the power supply and see if that helps out. Thanks for the suggestions!
