Hi I'm not really to into hardware of a computer. But I'll try to make this clear as I can. I own a stock Hp a810n Pavilion. My Northbridge Headsink fell off and the thermal paste is pretty used. My question is basically. If this happens would that be cause for my psu to rapidly blink? I checked everything unplugged all power connections and I know my psu is good. once I plug everything in it blinks. I took out my ram and it still blinks (incase the ram was misplaced in there). Thanks for anyhelp Will check this quite frequently for any questions. For exact mother board specs here is a url. Asus K8S-LA (Salmon) I believe >__> Thanks - Entropy.
