Computer starts up but there is no POST. All Cables and monitor fine. No picture on in built MOBO graphics
Hello
So a few months ago now my computer suddenly turned off while I was playing a game online. It was hot in my room so I thought it had automatically turned off to stop itself overheating. So I left the computer turned it off and the next day to my horror it was turning on and off very quickly booting up again. I tried to troubleshoot the problem but I couldnt tell. So I took it to a computer shop who told me the MOBO was fried and had scorch marks on it (which I couldnt see). So I changed the motherboard and the computer now starts up running, however there is no picture or POST. There is also two beeps one smaller beep and a louder one. The HDMI cable works and so is the TV but there is no picture coming to it from the onboard graphics in the MOBO either. I was going to give it to another PC repair shop because I have no idea but because of lockdown im postig here.
Thanks
