Re: Broken computer
Well, I believe the technically correct answer there is "Yes," but that's like saying your TV is trashed because you vacuumed while it was on... It's possible, but the chances are astronomical. Unless your PC is under high tension power lines, next to a dynamo, inside a reactor... the location should have nothing to do with it.
They're stupid and don't know the actual problem, so they're trying to pin this as your issue so they can stop support.
Yay, the fun part(?)
Issues that persist through install are typically (IME) due to corrupt Windows kernel files. Now you might say "Umm but I reinstalled Windows!" Yes, that may be so, but I'll bet you didn't know (as most M$ employees even don't) that Windows will search the physical makeup of the drive to search for kernel files, and then use those if present. So, here's how to resolve that.
Get DBAN, burn to CD and then boot from it. Press Enter to go into interactive Mode, then M when loaded and select the Quick Erase Method. Press space to select your drive (verify the size in GB to be sure you get the right one). F10 to start.
Let that get to about 50% and all Windows traces are gone.
Reboot, go into the BIOS and restore defaults.
Re-install Windows and post back.
EDIT: Get drivers from Manufacturers site (e.g. AMD or Nvidia).
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
