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.

I don't get BSoDs anymore, it just powers off when browsing the web...at the owners house. I have it at my place now and haven't been able to re-create the problem. There aren't any memory dumps since I rplaced the HDD and restored the factory installation. Any other thoughts/ideas?

Hello Kurosaki,

Sorry for the late reaction its very busy at work here,

Im glad to see the new hard drive works out, that you maybe have rooted out the problem right there, now what u can do is, attach the drive to the pc and run a full check with the WD Diagnostic program...
Or in dos with the Hitachi DFT.

IF it gives an error that will be most likely the problem... if it does not however, then i advise you to do a antivirus check on that old drive. in this case, the old drive is still in good shape and is able to be used.

Hope i could help.

Please understand, it's not the hard drive causing the problem, I replaced the old one (which is in a landfill by now) because it kept generating problems with the file system. Now I know that the drive was damaged due to the constant loss of power which ONLY occurs at the owners home and ONLY when browsing the web. I've checked for viruses with Malwarebytes' and Combofix, not to mention that the PC is loaded with MS Security Essentials (don't know how reliable that is) and Norton Security Suite (which I know first hand isn't worth anything), no virus's have been found, ran RKill and TDSSKiller before scanning to ensure that particular stealthy virus could be detected.

So the issue is power, I'm reasonably sure it's not the PSU since everything works fine at my place, it only powers off when browsing the web at the owners house. When I ran out of ideas I suggested trying another ethernet cable, instead she plugged it in to her laptop without any issues. I'm trying to find out if anyone has experienced anything similar to this and/or troubleshooting ideas, no matter how unorthodox. Thx red_devil028 for at least taking notice and trying to help.

hello again kuro, sorry for the late react, its weekend and then my mind goes more into outside life then into tech stuff ((hell job sometimes))

Maybe at this point of your last comment it is good to look at the capacitors of the mainboard.... if that is not it, please do a mem test... if that all works i have no clue other the PSU, however... at her place...

What you could try is make sure the USB hardware is unplugged at her place... and then plug em in day by day... it could be some of the soft ware of those hardware is fighting with the Operating system... so in that case just ask her if she could do that and call back notifying you what she last plugged in... then test the two together to see if you can solve it.

Its one of the strangest things, but thats part of what makes the job challenging :D it takes time and after this one you ll know what to do with the next surely!

Hope it helps
