I recently build a desktop computer. As soon as I switch it on, it switches itself off for 3 seconds and after, switches itself on!!! Nothing has been installed yet. No Windows or nothing.
What could it be the case?
Also, the graphics card is as hot as fire without even having Windows on it. I just turn the machine on and go to BIOS, it turns into heat machine. VGA requires about 400W. I connect 4 pin mains to the board not 6 pins.
