PSU Power Surge and BIOS access issue

Crash Override

Hi All,


I'm hoping you can help. I'm not sure whether or not my two issues are related or not which is why I am including both here instead of two different threads. (If they need two separate posts let me know).

Issue #1 - PSU - Power Surge



On two occasions while Playing F1 2019 game the PC restarted itself out of nowhere. POST told me it was due to a power surge. I put the first one down to a once off and maybe there generically was a surge in the house. After the second one I knew something was wrong. A third restart happened a few days later (not playing the game) and I seemed to be unable to turn the machine back on. Tried again the next day by removing everything except board and slowly added stuff back in except GPU. Today the machine did another restart randomly (system was idle with nothing open and I have taken out the Graphics Card out of the machine so only using iGPU). POST then gave me the specific error "ASUS Anti-Surge Was Triggered to protect system from unstable power supply unit"


Before I go out and by a new PSU - is there anything else that could be causing this issue? I have Hardware Monitor downloaded but I have no idea how to read it to see whether there is unusual power activity.

I was going to check in my BIOS for any sign of Power issues but this leads me to issue #2.



Issue #2 - BIOS.


I cannot boot into my BIOS. When I press DEL or F2 the screen goes black as if it's about to load but does nothing, I have to hard shutdown and start again to boot to Windows


Troubleshooting done:

- Reset CMOS with Jumpers

- Reset CMOS by removing battery for 5 mins

- Turn off Fast Boot

- Attempted to update BIOS to the last version that was released and get error ( This tool is for BIOS Update to support new Intel 4th Gen Core processors. please ensure that the Intel Management Engine Interface Driver is properly installed before using this. With a Yes and No options but Yes is greyed out.)

- Intel Management Engine Interface driver is installed and working and updated as per Device Manager


Any ideas on the above would be most helpful.


Thanks.

"Surge" is a user friendly term, the board likely doesnt know whats going on just that the PSU is flaking. I doubt that setup has PMBus so the PSU wouldnt be reporting status messages to the mobo. PSUs are a high fail item so its a safe enough bet without any further troubleshooting.


Your second issue is likely just a video error, outputting 60Hz to a 50Hz panel etc. Your board+CPU should be capable of outputting displayport without the GPU, I'd try accessing bios with the 1060 removed and the cable moved over to the mobo.

Thanks for your reply!

Yeah figured as much on PSU just wanted to check if there was something I could check that I might have missed.

For the BIOS issue, unfortunately the same thing happenswithout the 1060 installed and just using iGPU. It doesn't go pitch black as if to say there's no signal more the brief blackness you see from the Pres 'F2 screen' to what is uspposed to be the BIOS menu. It's gets stuck in between there.
