So in short my problem is that my computer turns on, but doesn't boot the OS, leaving me staring at a blank screen. The issue started a while back when i upgraded the wireless adapter in my computer. the adapter i was using was starting not to function properly so i purchased a new one.(the one i had originally was an ASUS PCE-N53 and the one i bought to replace it was a TP-LINK N900 and both of them are PCI adapters)
When i went to swap out the parts the instructions for the ASUS adapter said that before changing adapters i had to uninstall the ASUS drivers that for the adapter. however when i uninstalled the drivers, the uninstall failed halfway through and blue screened my computer (the error code it gave was IQRL_NOT_LESS_OR_EQUAL). then the computer restarted itself and sent me back to the login page. When i tried to type in the password for my account it blue screened again with the same error code.
This happened five or six more times before i gave up and just cut the power and swapped the ASUS adapter with the TP-LINK one. This actually stopped the blue screen from comming up. However now my computer wouldn't boot every time i turned it on and i had to cycle to power a few times to get it to boot up properly. However once it got started i wouldn't have any issues.
After doing some searching i found that the drivers for the ASUS adapter had not been fully removed so i went and tried to remove them again in the hopes that it would solve my boot issues. Then during the uninstall a window popped up telling me that in order to remove the drivers the ASUS adapter had to be in the computer. so i turned off the computer and swapped the adapter back to the ASUS one. When i turned my machine on the same thing as before happened: sign in, blue screen, restart, sign in, blue screen, restart, ect.
Since that wasn't getting me anywhere i cut the power again and swapped it back to the TP-LINK adapter. But this time the problem had gotten worse, the computer wouldn't boot at all. I have no idea how to fix this so any help whatsoever would be deeply appreciated.
Things I Have Tried:
+using the ASUS adapter
+using the TP-LINK adapter
+removing the adapter entirely
+removing the GPU
+removing the drive
+removing the drive and trying to make it boot of the windows 8.1 OEM disc
+trying to boot a different OS of a completely different drive (a friend lent me a hard drive he used for testing PCs, it used linux and nothing came up)
+trying to boot my drive on a different computer (problem is probably a lot bigger than a bad driver because now the second computer i used to test my drive has the exact same issue)
