I have a Lenovo A58 slim-line Pc that is having a weird issue, I htink it is the power suppoly, but I'd like to get other opinions before I order one.
After the Pc is up and running for ~5-10 mins, the screen will turn black and the cooling fan will spin up to max; it sounds like a jet plane. The Pc will be unresponsive until I power it off and on. I ran the hardware diagnostics from the "toolbox" (full system), and EVERYTHING came back "OK", however, none of the tests actually test the power supply. I don't have another Pc here to swap it out and see if that is the root cause, but I don't know what else it can be. The Pc was in service for quite sometime before this issue started, and it is out of warranty.
