Hello, I recently built a PC and installed windows 7 for refurbished PC. Something went wrong and I had to reinstall the OS all over again. I was able to reload the second time but internet explorer wasn't working. I reloaded the windows 7 the 3rd time and now it does not want to reload with an error of hardware or software failure. i upgraded the memory from 2gb to 4gb which worked on the second reload but was too slow and internet explorer wasn't working at all. Like i said the 3rd reinstall was coming out with failure. Any suggestions? Thanks!
