But that doesn't matter. Be sure to give the old hardware settings in the BIOS a try. For example I will disable the onboard sound for a test run. If there is any hardware I can remove or disable I do that.
But it sounds like the machine has some issue. But the clues here do not tell us what it is.
So I will sum this up as quickly as possible. I have a background in IT and I've fixed and built plenty of my own machines. But this time I'm stumped. I have a Dell M4400 and I upgraded it from Vista to Windows 7. It was working fine and now it just hangs at the welcome screen when I boot it up. The pointer works, I can even tell things are working in the background because it downloaded and installed some updates when I rebooted it once. Even in safe mode it hangs at the welcome screen.
Then it gets even more weird. I tried to reinstall windows 7 again and even did the repair install. The repair install didn't fix anything. But when I tried to go through a new install it hangs at the screen where I check a box and say I agree to the terms, etc. So that was really odd. I even tried a formatted drive and the new install hung at the same spot for the agreement.
Up until these points everything works. The pointer moves, I can click, but when I click on the user icon on the welcome screen or on the checkbox for the agreement nothing happens. It's very odd. Anyways I have no way of explaining this. It apparently isn't the hard drive. I ran it through memory test, etc. So any suggestions would be great. Thanks guys!
