I have an Asus K7M motherboard that was pulled from a known working system.

When I power it up now the HP logo image will display but that's all. I also can't get into the bios setup either.

I was using a newer psu but swapped to it's original to test that with no change.
I've tried swapping the ram but that didn't work.
I've reseated the slot cpu.
I pulled and reinserted the clock battery and shorted the pins to clear cmos.

I'm not sure what else to try.

That computer it was in had not been used in a while but booted fine the last time it was used.

Can you flash a BIOS image from Asus into the EEPROM? Maybe the POST shows something useful, or even resolve the issue just by reprogramming it.

Any beeps from the PC speaker?
Or get a (proper) diagnostic card.

I've had systems hang on the POST screen when there is an IDE cable plugged in to a dead IDE drive or a drive that doesn't have power. One of many reasons to pull the board and strip it down to the bare minimum when troubleshooting.

After watching many YouTube videos about older computer hardware, YouTube began recommending videos about trains - are they trying to tell me something?

I get one beep, which I believe means all good. I did get a memory error beep which trying out other sticks but the original one doesn't cause that.

I might need to buy a card.

Currently all that is connected is
CPU - AMD - Athlon 1000 (AMD-K7100MNR53B A) - Original
One stick of ram which is the orignial
GPU - XFX Geforce 4 TI 4200 - I did try the original but no change.

The keyboard is a ps/2 one which I know works.

The Caps, Scroll, and Num Lock lights turn on/off when their key is pressed.
