Motherboard Issue? [SOLVED]

addarcia · 16 Mar 2020 at 18:01

Hi!

So I’m done building my first PC, and everything appears to be working … but I can’t enter BIOS. I can see the TUF GAMING splash, with the instruction: “Please press DEL or F2 to enter UEFI BIOS setting”. However, when I press/mash either key, nothing happens. I thought it was an issue with my USB keyboard, so I switched to a PS2 keyboard – with no success. Another troubleshooting note: the motherboard’s boot LED (yellow green) is constantly on.

Thanks in advance.

My Build:

AMD Ryzen 9 3900X
ASUS TUF GAMING X570-PLUS (Wi-Fi)
Crucial Ballistix Sport LT 16 GB (2 x 8 GB) DDR4-3200 Memory
Gigabyte GeForce RTX 2070 SUPER 8 GB WindForce OC 3X
LG 27GL850-B 27”
NZXT H710 ATX
NZXT Kraken X53
RIOTORO ENIGMA G2 850W 80+ Gold
Seagate 2TB BarraCuda Internal Hard Drive
WD Blue 1 TB M.2-2280 SSD

P.S. all fans are spinning, and the motherboard RGB is on.

Hi!

Yes, I am; it's plugged into the GPU. When it's plugged directly into the motherboard, there's no signal.

I tried disabling DisplayPort 1.4, and then using an HDMI cable, but there’s no change.

The screen isn’t blank post-POST; the TUF GAMING splash is constant, as is the instruction (to press DEL or F2). To a novice like me, it seems as though my keyboard isn’t working (though both the USB and PS2 keyboards light up).

I just cleared CMOS using the jumper and the battery (I had to remove the GPU to access it). Now, along with the constant boot light, the VGA LED is now lit. It's a comedy.

Just checked to see if the GPU was improperly positioned, but it ain't. No idea what could've happened.

Per your suggestion, I tried removing the M.2 SSD without success. Re: CMOS clear, is that advisable while the system is running?

No progress I’m afraid; I’m going to disassemble my system and put it back together again … perhaps there’s something I’ve missed. I’ll update you afterwards. In the meantime – thanks for your help! Much appreciated.

Hi again,

So… I set up an open bench, reset and reseated everything: alternated RAM sticks/slots; moved GPU to the second PCIEX16 slot; reset CMOS via its jumper and its battery; attempted to boot via the HDD alone, then the SSD alone; applied a touch more thermal paste; tried HDMI/DisplayPort slots; a USB keyboard and a PS2 keyboard … and no change. Well, I’m back to where I was. The VGA LED is no longer lit, but the boot light remains my Northern Star.

The TUF GAMING splash screen appears, but I can go no further, no matter how violently I mash DEL or F2.

What’s next?

Hi!

Apologies for the late response, but life's been quite strange, recently.

My PC is now working, thank God. The solution was: I disconnected both my SSD and HDD, which allowed me into the BIOS menu. I then reattached my HDD (as my SSD wasn't cooperating) and installed Windows (onto the HDD). From there, I updated BIOS / motherboard drivers, before booting Windows from my flash drive again. This time (after updating), I reattached my SSD, installed Windows onto it, and everything worked as it ought to have.

It seems that it was solved via updating the version(s).

Thanks once again for your help, @The Old School Gamer!
