System won't boot

[Elseano14]

So, my PC was running stupid hot because of bad contact, so yesterday I swapped the cooler for a 212 EVO. Yesterday it work fine, was perfect. Today I booted up just fine (if a bit slowler than usual) tthe immediately experienced a full system crash- system turned off and everything. I've tried to reboot several times and windows ten offers to do a system restore to when his wasn't happening, and I've been getting nothing but the windows logo for the past 10 minutes. My application of the paste was not the best, could this by a short? Or would a short make my PC just not work at all? Any idea what I'm looking at here?

To any people of the future who find this by Google search, I solved it- kinda. I left system totally unplugged for 24+ hours- by my guess like 36, and after a VERY long boot (3 minutes) it was running again. 

Cheers.
