Question PC Keeps Restarting After Shutdown

[NicholasJB1996]

Hello everyone,

I posted another thread a couple days ago regarding my USB 3.0 ports that stopped working randomly. The issue wasn't solved and I'd count the thread as pretty much dead at this point. So I decided to purchase a USB 3.0 to PCIE expansion card and plug it in. It works great except the only downside that came with plugging in the card is that when I shutdown my PC it will shutdown completely and immediately boot back up. I did get it to shutdown completely once when I unplugged any USB devices from the card and uncheck the option for "Allow the computer to turn off this device to save power". However, I enabled that option again and tried playing around with other settings and have not had any success since then with anything else.

So far I have tried installing the driver for the card.

I have uncheck the option for "Allow the computer to turn off this device to save power".

Unchecked "Allow this device to wake computer" on mouse.

Checked BIOS for any options that could disable the wake on USB but there is none.

Not sure what other options there are that I could try to get this issue resolved. Any advice is appreciated.

update the bios of the motherboard
did you plugin the power connector to the pcie card?

I'll look into doing that later when I get home. I didn't plug in the power connector since the CSR that sold me the card said it would get power from the PCIE port on the board. My PSU also does not have the 4 pin connector to plug into the card.

your PSU should have 3 4pin power connectors, plug one into the card

I never really noticed it but I'll take a look when I get home and update the thread.

I plugged in the 4 pin connector to the PCIE card. My BIOS was at the latest version which is FD with BIOS date 02.26.2016 but I still flashed it anyways. When the BIOS flash completed I selected the option to power off but the computer still rebooted after shutting down. What should I try next?
