As the title says. I also cannot turn it off once it's on without switching off my power supply. New ram as well. The gpu fan sputters on a pattern after turning the pc on.

Gpu: Gtx 1060 sc evga single fan
Ram: 2x8gb corsair vengeance ddr3 rub
Psu: Evga 600 Bronze
Motherboard: Asrock ab350 gaming k4

Sounds like a power supply problem, 12 volts (for the fans and drives) works but the CPU needs 5 volts to start.  Either the PS failed or there is a problem on the MOBO not letting 5 volts to the CPU and the rest of the unit.

Alright thank you, I will try to test a different power supply and then I will post results

Your motherboard has integrated graphics.  Uninstall the dedicated card and see what happens with the integrated graphics.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

I switched my power supply and now I can turn it off, but still no picture. No bios or anything. Also took my gpu and plugged in hdmi to motherboard with same results.

Whenever I have this issue I find its best to remove everything from the case and run it on a table to eliminate any shorts.

Usually comes from incorrectly or extra case standoffs touching the bottom of the mobo - touch the PWRON jumper and its a screwdriver on both pins to get it to run.

R5 does NOT have integrated graphics, even if mobo has the connectors, it's not built into the CPU
