Re: Software or Hardware
Oh Windows, how I hate thee...
First off, you never really formatted the harddrive. Most format operations do little to nothing to the data that's on the drive. To be 100% sure that there is absolutely no data left on the drive, you should download and boot a little program called DBAN. See, Windows 7 has a terrible install process. It looks at the drive for existing files even after a so called format. Even though you just formatted it, they are still there and Windows sees the binary equivalents and reuses the faulty files. 'Nuking' a drive and then installing Windows is the only way to be sure that you have clean files.
From there, you should enable the Blue screen of death and logging. Most people think that Windows 7 did away with the BSOD, but it really just hides it now. Right click on My Computer and click properties. On the left, click the "Advanced [...]" link and then there should be a Startup and Recovery settings button. In there, uncheck the "Automatically restart [...]" option. This way, when the BSOD does happen, you will actually see what failed.
After you do that, update the computer completely before installing any third-party software.
Now, if it does fail again, you'll be able to track down what is going wrong. If it does, you can boot into Safe Mode and do a System Restore to a time before it started to fail. This should help identify if it is software related (which it sounds like it is).
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?
