A new client called me for help. Here is the whole story. He has a gaming computer with a Gigabyte GA-F2A88-YM-D3H motherboard and a GeForce GTX1050 video card. A friend of his suggested he replace his motherboard to improve perforance. He purchased whatever it was his friend suggested not realizing his CPU was not compatible. He had already completely disassembled his PC so he had to put it back together. Once he did it initially would not power on. The lights and fans would come on briefly and the go off. He disconnected everything and reconnected one piece of hardware at a time. It would then power up as he added each piece of hardware until everything was back in place. Now the PC powers up but there is no video. I have removed the video card and tried the onboard VGA and DVI connections. No video but when the cable is plugged in the monitor will initially flicker as though it will come on but it just goes back to powersaver mode. I have tried multiple monitors woith no luck. I have also removed each RAM stick at a time but still no video. I tried using known good RAM but still no video. I removed the CMOS battery and reinstalled it but still no video. Are there troubleshooting steps I am missing? Please advise.
