HI all,
Need your help guys in resolving mystery with what's going on with my PC after recent bios update as I'm simply out of ideas and about to throw out PC over the window.
Some specs first:
Asus Maximus Hero Z790
Intel 13900K
32GB RAM - 2x16gb DDR5 TeamGroup FF4D516G6400HC40BBK 6400Mhz
Drive m.2 Evo 980 1TB
GPU TUF 4080 Super
PSU 1000 Watt
After upgrade from bios ver.1801 to ver.2703 I experienced nothing but crashes, freezes, BSODs...
Reset bios to default, cleared CMOS, but shortly after screen went black right after post code. Black screens happen randomly, but in 90% cases they happen right after post screen. Sometimes I can hear windows loading and playing sounds, but screens remain black.
After I have successfully installed Win11 (USB) I started getting multiple freezes/hungs which I had to hard reset each time. I've tried several different BIOS settings to make it more stable, but without lack, hence being completely helpless I decided that I'll go back to bios 1801 on the next day as it was already getting very late.
On the next day I have downgraded bios to 1801 hoping everything will get back to normal, but it's far from being OK. Resetting bios default and clearing CMOS is standard procedure...
I have removed all external components from PC, resettled RAM, tested RAM, GPU and tested m.2 drive to narrow down source of issue, but no luck. No errors found.
Having installed bios 1801 black screens are gone and PC boots normally, but I'm unable to complete windows installation. Thinking of possible faulty m.2 I have replaced it with spare m.2 drive and wanted to do clean windows installation via USB...no luck either.
I've isolated 3 scenarios repeating almost each time when trying to install Windows.
1. Windows is installed, after reboot it throws error that he isn't able to complete installation so I can only start all over again. SFC/DISM commands didn't resolve it.
2.BSODs ... always when I run Windows Installer, almost each time BSOD would throw different error. KMODE exception, WDF_Violation, IRQ..., Faulty Page....etc .etc.....
3. Very rarely system would freeze with graphical glitch across the screen resulting with hard reset.
(like a half of installation menu/window is visible, causing immediate reboot)
The only this I haven't tried yet was to install windows on regular sata ssd, other that that I have no idea what's going on.
RAM ... my RAM was on Asus compatibility list, but I must admit I had some challenges from day 1.
Asus motherboard never wanted to read it as 6400Mhz, so I stayed happy with 6000Mhz. However new bios AUTO DRAM frequency locks on 4800Mhz and that is the MOST stable setting for this RAM. Setting DRAM in bios to 6000 or 6400 is not passing you through post screen during boot.
Need your help guys please as I get stuck here and really don't know what else to test or what bios settings to change. I can still RMA motherboard or Intel CPU, which both have valid warranty, but I would be more happy to fix it.
Ask me anything, guide me to fix it please...I'm here all for you.
