My laptop has been having this problem ever since I first tried Windows 7 since 2009. What happens is, sometimes, when I reboot it, it just hangs infinitely as described in my title. I can't ever really reboot it, so normally I just put it on standby and avoid installing critical stuff. When I do reboot it and get lucky that it doesn't hang forever, I have to make a full image using a backup utility so that I can restore it. I tried many fresh installs already but this always happens. What could be the problem?

Several reasons for a black screen.

  1. Anti Virus software (Symantec) can cause this, change brands

  2. Video drivers can cause it, update the driver, or a bad video card/chip

  3. File system corruption within the $Txf directory, see this link. Article was written for Vista but also applies to W7, although it was more common in Vista for some reason.

  4. File corruption is the most common reason, it could be any critical file needed to load the OS, from the Master Boot Record to $Txf folder.

Yes, I think it is the 3rd or 4th reason. The thing is, how do I prevent file corruption of critical files needed to load the OS? Note that I even when I do nothing critical to the system, like install new drivers or update, it still happens at least 80% of the time. – chiurox Aug 2 '10 at 3:59
It could be a bad memory module, bad hard drive, or motherboard. How old is this PC? – Moab Aug 2 '10 at 14:48
My laptop is pretty old actually, almost 4 years. I don't think it's a bad memory module since I recently changed it. It's hard to say it's the motherboard. I guess it's time to get a new laptop? – chiurox Aug 6 '10 at 18:45
