HELP! WINDOWS 10 IS KILLING ME!!

[liamnipen]

I got this pc used with a XFX AMD HD 7970 3GB and a MSI Z87-G43 just like the one i have, and everything else is just like it is now, but when i was going through my cpu (because it was around 90 celsius) it turned out to be the old paste, so i got new paste and took out the cpu cleaned it and put it back with the air cooler, so i turned on my pc and it was not booting just a black screen with code in the bottom right saying “A2”. It turned out that i had bendt some of my motherboard cpu socket pins, i tried bending those that where bendt but no success. tried to hot swap the sicked with extreme heat, but no success, so i bought a used motherboard with a old “crappy” AMD FX6300 that i managed to overclock to 4.3GHz with around 70 celsius with cpu stress test. I got a used MSI Z87-G43 that is just the same as i had before, then installed my I7 4770K onto the motherboard then plugged and played. so that was successful but i now wonder if the swapping might have affected the drivers, or windows. because when the swapping happened i did not reinstall anything i just plugged in and played, don’t know if there is any other way to swap a motherboard, if there is and i might have up this with the swapping tell me. Whats weird in that case if this is the cause of the problem then why did the pc break down now when it has been over 4-5 months since the swapping back to a MSI Z87-G43 back.

I should also mention that when i wanted to overclock the I7 4770K on the motherboard i have now. it showed 127 celsius nonstop on “speedfan” havent tested any other programs, but i know it never was at 127 celsius because i checked it with my fingers. So i gave up on overcklocking it because i wanted to know how hot my CPU really was when overclocking so i would not kill it. I guess the temperature meter is dead or messed up.
