Screen goes black and pc won't re-boot

What is the error message? The CPUs will not overclock on there own, that requires configuration. Some components when not installed properly with cause the computer to boot to a black screen and the fan to speed up dramatically. I've seen memory sticks and display port cables cause this. Check all your hardware and make sure everything is seated properly.

Try this:

If you're booting up the device and it goes thru the Post test and then goes to a black screen this usually means your OS has crashed.
You will need your Operating system or Recovery Disk.
I hope you've backed up your data and files.

Good Luck!!

The screen goes black then comes back. When it comes back are you able to use the computer without any problems? When does this happen? Most times during the boot process the screen will fade in and out.

If this is not happening when you boot the system it's possible that your lcd screen might be going bad so keep an eye on it.

try a system restore that will bring the laptop back to an earlier time before this happened, if successful your settings should restored. Why did this happen? bad download, a bad device driver, or program compatibility.
