Hello, 

 

My work computer restarted itself yesterday and when it booted back up, all I see are colored rectangles and odd symbols flashing on the screen. I can access BIOS but have not tried a live cd. I would like to keep the OS intact so my data won't have to be reloaded if possible. 

 

I am running the latest windows 10 updates on a Lenovo Thinkpad. Any help would be appreciated. Thank you!

I'd suspect your graphics card. If you can swap it with another one, it will at least overrule the card.

 

I can also be caused by overclocking. Is your computer overclocked?

 

Then, there's overheating. Make sure your computer is clean of dust.

 

There could be a problem with defective memory.

 

The BIOS may be improperly configured.

 

Finally, a problem with the power supply.

Can't swap cards. This is a laptop with onboard graphics

It is not overclocked.

I've already replaced the thermal paste on it and cleaned thoroughly,

Wouldn't the bios have to be tampered with in order to be configured improperly? It was running fine yesterday nothing was messed with in BIOS.

I'll run memtest and see if it comes up with anything. 

 

Thank you for your input!

OK, try the Memtest. Can the computer boot-up anyway? I'm guessing it's impossible to see anything? Just for the sake of it, have you tried Safe Mode? In Safe Mode with Network Support, you can either look for a video driver update, or reinstall the driver itself.

The graphics are ok. This isn't a bga problem because I can use bios just fine without any graphical issues. The screen in the picture I supplied shows the graphics great, nothing will boot though. Ive seen bad gpu's and the effects, and I don't think this is it. After the first Lenovo screen, where  you can enter bios, it goes straight to the odd colored screen in the picture, so I don't know if I can even boot from cd. Can't try safemode
