PC turns on automatically
Hi, I have problems with my PC. It turns on automatically. The computer is connected with UPS. When the computer is turned off but the UPS is on, the computer after some moments turns on. So, I have to turn off the ups. I don't know where is the problem, I thought that something is wrong with power button of computer so I changed it with knew one but again the same happens. I want to note that recently I have changed the old motherboard and processor with new ones and there were some power cables that I connected to the motherboard. Maybe I didn't connect them correctly? But if I didn't connect them correctly the computer wouldn't work. Where is the problem? Is it because of the UPS? Please help.
