My computer has recently been experience system (Bluescreen with WHEA-UNCORRECTABLE-ERROR), and after troubleshooting for hours, I gave up. So I brought it to a tech support person. The man took the pc for a couple days and returned it saying that he had te mporarily fixed the issue and to call him back later if it came back. He told the issue was in my hard drive and that there was a corrupted spot on the drive and he had 'taught' the drive to stay away from it, and never write data on it again. He then promptly charged my $120 and sent me home. After a few days, the problem started occurring again. I just want to know before I bring it back to this guy, is he bullshitting me?
