A blank Explorer.exe window appears on boot
Many things can happen when your PC boots, but one thing that shouldn’t appear is a mysterious window. Some users have reported this problem, however, which takes the shape of a blank Explorer.exe pop-up with no text and an OK button.
There are various things that can cause this problem, but whatever the source, the root cause is the same; an erroneous Load value in your registry. To see it, do a Windows search for “regedit” to open the Registry Editor, and then use it to find the Windows registry fold.
In it you will see an entry called Load, which may or may not have data associated with it. Get rid of that entry and the blank box will go away.

DRIVER_IRQL_NOT_LESS_OR_EQUAL blue screen of death
While the dreaded blue screen of death can occur for many reasons, perhaps the most common message flashed alongside it is the dreaded “DRIVER_IRQL_NOT_LESS_OR_EQUAL.” This bizarre message is trying to tell you that Windows has crashed because of a problem with a driver.
If you pay attention to the additional text that often appears, you may be able to figure out what driver is the root of the problem and proceed from there. However, since your PC automatically restarts, you may not have time.
You can find BSOD error dumps in the C:/Windows/Minidump folder. Wading through them is not an easy task for the average user, but if you look for names associated with hardware in your PC, like “Nvidia” or “RealTek,” you can probably spot what happened. If not, you can try talking to the helpful folks at Microsoft’s TechNet, who can analyze your dump file and pinpoint the problem.
You’ll need to upgrade the drivers for whatever you find to be the cause of the problem. If you still are plagued by BSODs, the issue may be faulty hardware, which means you’ll have to replace the offending part.
