Windows 8 "Certified" laptop reformat issue. Featuring graphics glitch AND Bios lockout.


Feb 4, 2016
OK guys. I'm completely lost here and on the verge of tears.

My sister has an Acer Aspire V5-531 series laptop. The Model number is MS2361.

So.. I live in a small town and I fix people computers.. by fix I mean run AV and MW tools, install new keyboards.. and occasionally reformat pc's. (I have refromatted a PC about a billion times.)

My sisters laptop is about 5+ years old now. and came with Windows 8 OEM pre loaded. Over the holidays she had mentioned that it was getting slow and she would just like to reformat it and check out Windows 10.

So.. being that I have done that for people a billion times.. I said I would do it.

It took me a bit to get the computer to boot from CD, but I was able to install a copy of Windows 7 and once that was installed upgrade to Windows 10. Everything was fine and dandy until ALL the updates where done and we booted up to the desktop.

[This is what the screen looked like](

[Another example](

So I thought it was a driver issue. Couldn't fix it for the life of me. Then Someone suggested that I plug in another monitor via HDMI cable. I plugged in my 60 inch TV and BAM.. crystal clear fully functioning Windows 10. (It's JUST corrupted on the laptop screen as soon as it hits the desktop... Load screens and safemode work perfectly.)

After some research it turns out it's a Windows 8 certified security system [UEFI & Secure Boot](

I would like to try the work around and at LEAST get Windows 8 back on the laptop.. but now the Bios has [locked]( itself. and I can't get the PC to boot from a USB OR DVD.

The lock key I get is [BA2BE493] However.. it has changed a few times.

Help.. please.. I CAN'T afford to replace this laptop.. there has GOT to be a way to get it back to at least functional.

TL:DR: Tried to install Windows 10 on a 5 year old Windows 8 "Certified" laptop.. and now I am locked out of the Bios and at a loss as to how to fix it.. Please I have been working on this for 4 weeks and I can't fix it!


Here are some troubleshooting steps that may help in solving the issue.
- First, you mentioned that when you connect your laptop onto an external monitor the display looks normal on it so it could also mean that the built in display of the laptop has been damaged.
- Do open the laptop first and make sure that the ribbon cable that connects the built in display to the motherboard is seated properly.
- If these doesn't solve the problem do load into BIOS and uninstall/reinstall the graphics driver.
- Uninstall the graphics driver from Device Manager and same in Programs and Features.
- Once done, download and install the latest graphics driver from the manufacturers site.
- If these doesn't work you may need to reload Windows again but regarding the locked BIOS please do contact ACER first about password related concerns.

Thank you for taking the time to respond. However.. it would seem that you didn't read the bulk of my post. I have tried everything you mentioned twice over.

My problem is the Bios has locked me out.

After some research it turns out it's a Windows 8 certified security system [UEFI & Secure Boot](

If I could get back into the Bios I could just try the workaround I posted. But I can't boot from DVD or USB if I can't get into the Bios.

Also the display is fine. All through the install process everything is fine... you can watch it load into Windows 10 and then "switch" to the corrupted screen.

Again.. I can't thank you enough for even responding. I am so lost here. and appreciate ANY help.
