Hey guys, I just installed a Noctua CPU cooler and now, once it's turned on, the fans start up but the monitor says "no signal" which I guess means it's not working (I have tried the monitor on another computer and it works fine so I know it's not that; same story with the graphics card and HDD). There is no BIOS. Also the HDD light pops on for about half a second after the computer is turned on but then it goes off. Any ideas on what's gone wrong? I get the feeling (vigorously) rubbing off the residual thermal compound on the CPU before adding the stuff that came with the cooler might have been a terrible idea but I didn't think that would destroy it?
