Computer left on for three nights, shut down, and now wont boot up

[peppster]

I'm not sure if it's because of leaving it on for this long, or the fact that I installed new NVIDIA drivers during the time it was on, but now when I turn on my computer, it will either boot normally, but stay frozen at the screen where Windows usually pops up; not boot up at all and give no signal; or sometimes on very rare occasions, work normally. What should I do?

EDIT: Also, when booting up, the computer may turn itself off, then back on

Try to catch it when it just starts to boot windows and hit F8 to start up in safe mode

Then un install the nvidia drivers and see how that goes

Also : You might want to get the most recent video driver directly from Nvidia's web site instead of windows update

I downloaded the drivers from the GeForce Experience, not Windows Update. They are the most recent drivers.

OK still try to boot to safe mode and then uninstall the drivers you installed or try to "roll back" the driver from Device managment
