PC doesn't post

[Findus0211]

Hi,

After Troubleshooting almost everything I can think of, my PC still doesn't boot. Ive done a BIOS update via Flashback, switched back to the original Mounting Hardware, tried booting with 1 Ram stick, cleared CMOS, tried a new CPU, removed GPU, almost everything. The issue is rhat first I get fast blinking [Memory] and then forever a VGA error [slower blinking] on the power button. 

Specs:

CPU: Ultra 7 265K

RAM: 32 GB Patriot Viper 6000 MT/s

MoBo: Asus Prime Z890-P Wifi 

GPU: Gigabyte 4080S

Cooler: Arctic Liquid Freezer III Pro 240 A-RGB

Storage: 2 TB Nvme M.2 Storage

PSU: Thermaltake Toughpower GF3 1200w

 

Thank you in advance!

Is this a new build or older PC? Was it previously working and then stopped working, or did you just build it and it doesn't work?

 

The PC doesn't boot without the graphics card either? Your CPU has integrated graphics so you can remove the graphics card and plug your display in to the HDMI port on the motherboard to get a display.

It was a build with a I9-10900KF previously and it worked before. I also plugged it into the MoBo and it still doesnt display video

10900KF would have required a different motherboard and memory. Other than the CPU, Motherboard, and Memory, what else was changed? Did you change power supplies?
