Pc dead

Mackenzie Donohoe · 22 Dec 2020 at 16:57

Hi i have an issue that my pc is not starting up. Initially it had the error message in below:

USB Device Over Current Status Detected ! !
System Will Shut Down After 15 Seconds.

Then it went totally dead and would not start up. I have not changed anything with my pc in over 6 month and also had a shop look over the issue who weren't sure. I then phoned Overclockers support who thought it was Motherboard related so I sent my motherboard in but now they said the motherboard is fine. My specs are as follows:

CPU- AMD Ryzen 7 3700X
GPU- MSI RX 570 8GB
PSU- TX 650 M Corsair
Motherboard- Asus ROG Strix X570-F
RAM- 16GB DDR4 kingston

I checked all connections, tried using different power cable, tried starting up with no usb devices plugged in and also ran PSU check that shorts out pins 4-5 to confirm PSU operation.

Can anyone suggest what may be the problem or help me ?

Thanks in advance

Have you disconnected the front case usb header to the motherboard ?

Try assembling the mobo, psu, cpu, gpu and 1 stick of memory outside your case (on a bench or table, not carpet).

Mite be worth building the pc outside the case to test with the minimum parts

Normally shorting is an issue on boot up. Could be PSU.

just to clarify, you press power button and get nothing at all? no fans start, no leds on motherboard or gpu?

If it is completely dead, not even LEDs and OCUK say the motherboard works fine, then it has to be the PSU for me? If the CPU, graphics card or memory were the problem, then the motherboard would still boot, well.., I think they would, most of the time.

Think you may be right with the dead psu, but out of interest what usb devices did you have plugged in when it died?

Ok so i got the motherboard back. Wired up essentials only and then started adding other items one by one. The USB 3.2 Gen 2 front panel connector (U32G2_C9 when connected is causing the motherboard lights to go off so i havent connected that. It seems to be faulty.

When my pc boots up now i go straight to bios cant seem to boot as normal.

Btw thanks for helping me get this far

mickyflinn · 23 Dec 2020 at 16:12

Cant seem to boot as normal do you mean from Your ssd ?

Mackenzie Donohoe · 23 Dec 2020 at 16:43

In the boot menu it says cannot find any bootable devices. Im not sure what normal is i just mean it would go straight into windows previously now it only goes to bios

If the bios reset maybes it's changed the drive configuration from ACHI to IDE or viceversa. If you have more than one HDD/SSD, work from the bottom up and only connect up the drive with Windows on it and test it in different sata ports on the motherboard and test using a different data(sata) cable.

listen guys thanks very much for the help.

I had to disable fast startup and turn on a setting to search for compatible devices. Im not too clued up on the full thing but happy that its working again. The usb devices at the top are still unplugged but i can live with that..

cheers
