Hey guys I was wondering if anyone could help. So yesterday my computer was working fine but wanted to clean it because it’s been awhile. So I went outside this morning cleaned it and came back inside to make sure everything worked. When I turned it on everything would seem to work. Fans would turn on and led lights would work. But unfortunately I wouldn’t get any output from the monitor and it would say no signal found. My keyboard and mouse wouldn’t even light up either. I’ve tried resetting my bios by taking out the motherboards battery and putting it back in after a few minutes but didn’t fix anything. Can anyone help please?
