We have a desktop that everynow and then we'll detach the side panel and clean out the dust stuck within it. Normally this helps the computer and it'll restart like normal, but this time was different. When we attempted to reboot it the computer seemed to not even attempt booting. The HDD indicator will flash a couple times, the CD drive will light up for a short moment, but after that it will not go any further. I'm not sure if possibly we may have accidentally detached something or nudged the wrong thing within it, but I looked it over when it did it the first time and everything seems to be snug.
Was there something that went wrong within it possibly?
