So, I was on my PC and while using it my pc crashed, nothing responding (not even CTL, ALT DEL) so after a few minutes decided to restart. Upon restart neither of my two monitors were receiving anything from my PC. I have tried disconnecting all external cables and holding down the power button while PC is unplugged but nothing happens. Please help, I need this PC for my A level work saved on it and to communicate with friends.
A factor that may be of importance, two days ago I installed a Nvidia GeForce 730 GT graphics card to run newer games. Please help, this PC is needed asap.
