I just put a new SSD in my computer, replacing an old one. Something I've done plenty of times before but this time when I powered-up the PC I get no display. When I press the power button all the fans spin and the hard disks power up, but the monitor just says 'DVI no signal'. I also don't think it is actually running through the boot process as I can simply press the power button to switch it off again (normally, if it boots, I'd have to hold it for 5 seconds).
I have an Nvidia card, no display on that (either thru HDMI or DVI) and also onboard graphics, nothing there either. I disconnected the new SSD, no help. I disconnected all drives, nothing. I took out the nvidia card and ran only with onboard - still no display. Finally I took out the RAM and cleaned out as much dust from the case as possible, that didn't help either.
Now I'm kind of out of options. Any ideas what could be wrong in there? I'm somewhat worried that I broke the motherboard while I was changing the drives over. Is that the most likely problem? Otherwise, what else could be causing the issue?
