Ok so i have a system that's about 4 years old, and I decided to try and overclock it to squeeze a little more performance out of it. I played around with the graphics card first on MSI afterburner and decided to try and overclock the CPU. After reading than a non K Intel CPU could be overclocked to its boost speed safely I tried changing a few settings in the BIOS. To be honest I am a complete noob at this and just blindly tried following an online tutorial. After I made the changes in the BIOS, and choose to save and apply the changes, the computer tried to reboot, but would just power up and I would get a black screen.

Troubleshooting tried so far:

Removed CMOS battery to reset BIOS after unplugging power. I also moved the CMOS jumper to reset the BIOS.

After doing these steps, everything is running and sounding normal (fans etc.) and I even saw a flash of the bios screen on the monitor for a split second, but then it reverts to a black screen. After trying to change input ports on the monitor it will just say no input detected even though everything is connected properly.

Any thoughts?


Here's my computer specs.

Operating System: Windows 10 Home 64 Bit
CPU: Intel Core i5 3570 @ 3.4 GHZ
Ram: 16 GB DDR3
Motherboard: Asus P8Z77-V LX
Graphics Card: Nvidia GeForce GTX 670 EVGA (2047mb)
Storage: 120GB PNY SSD (Boot Drive) 2TB Toshiba HDD

Thanks

Resetting the CMOS will change your date and time which will need to be corrrected but it also sets the primary video to the iGPU, plug your video cable into the mobo and then go into BIOS and set primary video to PCI-E/PEG so you can use your Discrete video card, also ensure the OS HD is set as the boot drive. Save, exit, shutdown, flop the video cable back to your GPU card and try

Not entirely sure what ended up causing it to work. I tried hooking the video cable into the motherboard but the screen was still black. I then unhooked the graphics card and tried hooking the video cable into my tv and I was able to get into the BIOS. I powered the computer off and hooked the graphics card back up and switched back and connected the video cable to it. I also plugged the video cable back onto the monitor and everything worked properly again. Thanks for the help.
