Operating System: Microsoft Windows 10 (32-bit)

I've cleaned my laptop and change its thermal paste for both GPU and CPU. Clicking the power button gives me blacks screen and blinking caps lock once in every 2 secs. How can I solve this? Ive seen that 2015 laptops says it's CPU not working.

Hi
Depending on the age of the PC and the BIOS vendor...
The 4th, 5th and 6th characters of the Serial Number give the age when it went thru the factory...

It seems that it was built in 2015, and  gives me a code for CPU is not working. How do I confirm that my CPU was not working? And what are my steps?

When I turned on the Power button the GPU and CPU starts to heat up, does that mean that my CPU is working? Thank you!

Hi

Dunno.

These things are normally keyed to fit only 1 way.

 

The FAN runs?

Remove the RAM and note any changes.
