First off, I'm no novice when it comes to PC diag and repairs, that being said, here's the problem:
I got a customer with a PC problem, it kept shutting off (not shutting down) whenever she was browsing the internet, always between 15-20 after starting IE. Also MS Word kept generating memory errors and causing BSoD. I brought the PC to my place, found file system errors and fixed them, and every time I double checked the file system, more errors were found. Replaced the HDD and restored the OS. No more problems. My customer was pleased until she browsed the internet again, still shut off the PC after 15-20 minutes of browsing. I installed a brand new NIC, watched her browse for over 30 minutes, no problems. 10 minutes after I left, the computer shut off again. Brought it back to my place, no errors.
At this point the only difference is the power source. The problem is consistent at the owners house only. She had the entire house re-wired about a month ago, but the problem started before that, and no other electronics are suffering from "dirty" power. I'm going to try her PC power cable in the off chance it's damaged. Thoughts, opinions, suggestions appreciated.
