I installed a driver to work along with my printer. The computer was not printing on the paper for some reason but it deteced that there was ink in the catridges. So i messed around with the USB ports and everything went out. Didnt think nothing of it because the wires are somewhat sensitve. When the Windows screen came on I could not move the mouse nor the keyboard. I replaced the mouse and keyboard but that was not the issue. I’ve used both PS/2 and USB but nothing works. They do work in my laptop with no problems. I’ve also tried plugging the all mice and keyboards into and old computer i had around the house and the mouse worked but not the keyboard. Do you think its a power issue in my apartment? I also realized that one of the fans is not running unless i tap the tower.
