The fan that cools the CPU was very dusty so I unhooked it to clean it. After hooking it back on my computer will start up but won't display anything. It should also be noted that there is a blue light up display on the front of my computer and that also stopped working.
I made sure every was connected right. I'm really stumped here. All I did was unplug and replug in the fan.
Is it not even displaying a POST screen?
Are there any beeps?
Double check you haven't knocked a power connector loose anywhere and that the monitor cable is fully inserted both ends.
