Good day everyone, sorry for any mistakes but English is not my first language. I have trouble with my computer ( gigabyte z170x gaming+ i5 7600k) that I hope you can help me solve. Yesterday i cleaned my PC and i reapplied thermal paste because it has been there for years. I did not remove the cpu from the socket. After everything was done i turned the PC on, and i can access the bios normally where everything seems to be recognized fine. However when the motherboard shows the A2 code for several seconds, the PC restarts. I have tried removing everything non-essential, even changing the RAM and Hard Drive, clearing CMOS but nothing seems to work. Have I ruined my motherboard or can the problem be fixed somehow?
