I have a slim RGH (corona i think) that i had installed a CR runner into at some point, when i switch it on the CR glitches once and then the fans spin really fast and i get a flashing red dot, how should i go about remedying this ?, it could have been a faulty board to start with and i can see that i have clamp fixed it at some point, its been sat collecting dust for some time now, should i remove the clamp and give it a blast of heat to see if that is the problem ?..im wondering if where it has been sat out of its chasis with the screws securing the heatsink instead of the original clamp its become faulty again...not sure what to do first
