I get a blank screen and four loud beeps and three short beeps but then I keep pressing the escape key repeatedly and it gives me an error saying "unsupported adapter installed" I tried doing a system test by pressing f2 it tells me that everything passed after I shut it down it still makes the same beeps

Let's perform Microsoft system restore and check,
System Restore returns your computer to the files and settings from the restore point. Your personal files and documents are not affected.
Turn off the computer and wait at least 5 seconds with the computer in a full off state.
Turn on the computer and repeatedly press the F11 key, about once every second, until you see the Windows loading screen.
If a language selection screen opens, select the language you want to use to continue.
On the Choose your keyboard layout screen, select the keyboard layout that matches your keyboard type.
On the Choose an option screen, click Troubleshoot.
On the Troubleshoot screen, click Advanced Options.
On the Advanced options screen, click System Restore.
Click Windows 8, click Windows 8.1, or click Windows 10 as the target operating system.
The System Restore window opens.
Click the Restore Point that you want to use, and then click Next.
The Confirm Restore Point window opens.
Click Finish to restore your computer to a previous point.
Do not interrupt System Restore when it starts. Doing so can corrupt your hard drive and create more problems. Click Yes in the warning that appears.
System Restore returns the computer configuration to a previous point in time and restarts.
Hope this helps! Keep me posted for further assistance.
