So, i have a friends pc in my house and here is the story. He bought it 4 years ago being a very good desktop at the time but at some point his graphic card failed, so he removed it and kept using his pc via a VGA cable directly on the motherboard. Then at some point one press of the power button wasnt enough to turn it on.. he had to reboot and know it maybe needs 20 reboots to actually give a signal. I can see all the fans and cpu and from the powersupply working .. but why doesnt it have signal? ( i double checked with other cables and this isnt the problem.)
