Did a system restore and now my computer will not boot wtf?

Hi there, Viruses and registry problems lead to this situation, use a good antivirus like Kaspersky or Norton and use a system cleaner such as Reginout to fix your problem. Also read this article I paste here for you. I hope it would help you out. Anyone using Windows has likely experienced the infamous ‘Blue Screen of Death’, a.k.a. ‘Windows Stop Error’. This is a common error that occurs whenever Windows senses a software, hardware, or driver error preventing it from operating properly. So basically, almost anything from a minor glitch to a major system malfunction can cause this error to appear. Sometimes this problem will go away with a simple reboot and you may never see the blue screen again. But more typically, the Blue Screen of Death (BSOD) is an indication of something serious and it will not simply go away. In terms of how to fix the Blue Screen of Death, there is no simple answer to that. Fixing it means first diagnosing the problem to find out what is wrong with your PC. If you are not one of the lucky ones who can fix the BSOD with a reboot, then you will need to do some diagnosis to resolve the problem. With all the possible reasons for the BSOD ranging from software to hardware, or hardware drivers, it is very difficult to list a precise set of instructions for every possibly BSOD. The first step is to narrow down the possible source of this problem. If you are seeing the BSOD randomly, even when in safe mode, chances are it is a hardware issue. If you have recently installed new hardware, this may be the culprit. One solution may be to remove the new component to see if the problem goes away. If you have not installed anything new, then you will need to investigate further. If you are not comfortable unplugging and re-installing hardware in your PC, this may be a good time to have a technician look at it. If nothing showed up on the scans, then boot up again in safe mode and use the built in system restore utility. When running your system in safe mode, you can still access all the recent restore points created by the system restore utility. Run your system from the last known ‘good configuration’. On the other hand, if you know a recent software installation is the cause, then restore to the point created at that date.

Just order a Linux CD, wait for it to be delivered. Insert it into the CD/DVD tray on the computer. Allow the machine to boot from the CD, install Linux. There you go, you've just replaced Windows with a much more stable and virus free operating system.
