Extreme CMOS/Windows corruption?

[Electron_Ninja]

Hi,

I'm having a veritable crap-ton of issues right now, and they all started today. I'll tell you everything I know, even if it seems useless

So I recently installed purchased a HDMI to DVI adapter so I could use an old monitor with my laptop (Dell Inspiron 5537, Windows 10), and everything was working fine. After a while I powered off my laptop, and the first problem emerged. Although the screen went blank, all the periphials and the status lights stayed on and the fan kept spinning. So I manually powered off using the button, and left. I got home today, powered on, and had to wait about 2 minutes for the laptop to boot. The Windows 10 lock screen background and time were also replaced with grey (My theme colour). Only the battery and wifi remained. On the enter password screen the windows 10 picture was gone, and the unlock time was massive. Once I loaded into the desktop, I noticed the second monitor wasn't being recognised, even though it worked yesterday. The start menu goes see-through with no buttons or tiles for a bit, and even opening chrome causes major lag. I checked, and all hardware was recognised, so... what is it? I know corrupt CMOS can cause the light problems, but the lag and lack of monitor recognition SCREAMS corrupt Windows install. Any help would be appreciated.

Thanks

 

EDIT: I have tried turning the laptop off and on again. No help

Re-install windows

A fresh copy of Windows wouldn't hurt.

Re-install windows

I'll give it a go, but my laptop came with Windows 8 and no discs whatsoever, so any suggestions on making an install disk?

You can use a program called "rufus" to make bootable USB drives as long as you have the an image/.iso file.

Your lappy probably has a partition that has the windows install on it. Try booting the PC hitting F8 and click repair your computer > advanced boot settings.

 

From there restore to factory settings.

Or there's a chance the Bios holds the Windows key. So all he will need to do is find a Windows 8 image of the same type (home, pro, enterprise) and "burn" it to a USB stick.

Yes this is an option as well.

Doesn't work from Win 8 upwards. Instead you have to let Windows start to boot then reboot or kill the power (hold power button for 4 seconds) and on next boot it will boot WinRE instead, if it doesn't then repeat it twice in a row, sometimes it works first time while other times it takes 2 reboots.

Or from Windows (assuming you've got UEFI not BIOS) just hold shift then click reboot from Start and you'll get an option to reboot into WinRE.

Thanks all. Booted laptop into UEFI like someone suggested and reinstalled windows 10 (there's an option in the reset menu). Everything was fixed, thanks for the help
