Monitor black when entering windows

[Vivac93922]

I overclocked my monitor to 75hz and my monitor was fine. I overclocked it up to 77hz and my monitor screen went black. I restarted my PC and I'm able to see the motherboard hotkeys pop up and the window 8 logo comes up, but when my PC enters windows my screen goes black. I'm able to do stuff still, but I can't see what I'm doing. Whenever I've reset my computer and entered advanced startup settings, where it displays options to enter safe mode as well as other settings, but when I press the key on keyboard to go into safe mode nothing happens my PC just freezes.

EDIT: my monitor is actually an all in one PC so I don't have the typical options a monitor has.

Did you overclock it within the gpu control panel?
If you backup your data. try the reset option.

I used a software to overclock it. It added the new hz options in my display options

Sound like it software also run in safe mode.

You might try booting from a rescue bootable usb/cd to delete that software from your disk drive.

I can't get it to run in safe mode is the problem. It displays no button to press to enter the setup to go into safe mode. Basically, I just really need an alternate way to enter safe mode....

You can get into safe mode anymore.
What is the name of the software? where did you download it?

It either reset(if you have your data backup). try the rescue bootable usb/cd to delete the software. or reinstall the os

Also, you didn't really explain that well how to use the rescue usb/cd. I do have tons of CDs I could use, but not sure what you mean. Also, I don't have the original OS disk.

I can boot into windows, but can't see what I'm doing. I'm not sure how this would help.

"I can boot into windows"
With the rescue cd?

"but can't see what I'm doing."
It to find where CRU did and undo it.

I would suggest you take it to a shop to get it repair.

Ok, I have a separate windows installed on my separate hard drive and I can access windows 7 from this and view files on my SSD, my main windows 8 OS, but not use the internet on the Windows 7 OS. So, should I delete something from my files from my Windows 8 OS?

 

[rgd1101]

If you have a working os. backup your windows 7 data, and reinstall it again.

or if the CRU programmer have a site, go ask to see what can be done to removed it.

Well, everything's <edited> I booted into Windows 7, but this isn't an activated copy, so I can't use the internet and also many other things were missing. Also, when I restarted my PC and tried booting from my SSD, where my Windows 8 OS is located, it still booted into Windows 7. I went back into Windows 7 to check if it even showed that I could set Windows 8 as my default OS, but there was only the Windows 7 option. Although that's true, it still shows the program files and everything on the SSD, so not sure what's wrong.
