Hello
The other day I was having difficulty finding the power button of a desktop pc so I pressed it many times but it was plugged off. After I plugged it in it turned on but gave me the warning that the power supply was unstable and there were power surges. The pc itself is a bit old, has a core 2 duo e5700. Does it means we need to replace the PSU?
Thanks
