Hi! @Britt87cody90,


Are you able to boot into BIOS or F2 page from the PC?


Do you hear any beep codes when you turn on the PC?


Please share the product number of the PC to assist you better.


Try the steps recommended below.


Performing a hard reset to resolve a blank screen issue


Completely resetting the computer can resolve many issues that cause a blank screen. Follow these steps to perform a hard reset:

  1. Turn off the computer.

  2. Disconnect all peripheral devices and remove all USB devices and media cards.

  3. Disconnect the AC power adapter.

  4. Press and hold the power button for at least 15 seconds.

  5. Reconnect the AC power adapter.

  6. Turn on the computer.

If you are able to boot into the BIOS page, try restoring the BIOS to default and check if it helps.


1.    Turn off the computer and wait five seconds.
2.    Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3.    On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4.    Press F10 to Save and Exit.
5.    Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6.    Follow the prompts to restart your computer.
