Hi, I installed a new cpu cooler when removung the old cooler the cpu came out with it (it was stuck to the cooler) after a while and using 91% Isopropyl I got it loose. After cleanijg the old paste off I installed the cpu back into the socket (maybe i made a mistake here never done it before) and installed the new cooler (corsair H60 liquid cooler). My pc now turns on and appears to be running but its usb ports arent picking up any input and the same issue with display, i have a black screen as of pc is still off. Please and thank you for the help
