Question Boot issues with new build ?

[SolidParadox]

Hello,


Looking for some help with a new PC I've just built. I had been gaming for a few hours, went to grab a drink, came back and Windows had crashed. It was still on the screen, but couldn't move the mouse etc. Power cycled the machine, all the lights turned on, motherboard graphics card etc. All Fans were spinning but nothing on screen.

Left it a few minutes, still nothing. Power cycled again. This time when it booted up I got an error that the PC has POSTed in safe mode. Was taken to the BIOS, I reset it back to defaults and power cycled again. Same issue, black screen, power cycle, POSTed safe mode.

So I took the power out and left it for 30 sec, plugged it back in, powered on and this time it booted up to Windows. Restarted WIndows just to make sure everything was alright... I am now back to POSTing in safe mode. Pull plug for 30 sec, Windows boots. Restart or shutdown Windows and the cycle repeats.

Things I have tried:

• Reinstalling Windows
• Removing all power cables from motherboard and PSU and reconnecting them
• Tried a different PSU
• Reseated RAM sticks
• Clearing BIOS
• Downgrading BIOS
• Removed all cables (USBs, HDMI) except for main screen DisplayPort

The system just does not want to boot unless the power is removed. When I do get booted into Windows, everything seems to be working fine. Can load games OK. Has anyone seen this before or have any other ideas?



System Spec:

• Motherboard: ROG STRIX Z790-F GAMING WIFI
• BIOS: ROG STRIX Z790-F GAMING WIFI BIOS 1202
• CPU: Core i7 13700KF
• GPU: MSI NVIDIA GeForce RTX 4080 16GB SUPRIM X
• RAM: Corsair Vengeance Black 32GB 6400MHz DDR5
• Cooler: Corsair iCUE H150i RGB ELITE 360mm
• Storage: 2x WD Black SN850X 1TB M.2 PCIe 4.0
• PSU: Corsair RMe Series 850 Watt
• OS: Windows 11

Flash the BIOS to the latest version which is 1303. Once you've verified that the BIOS was flashed successfully, clear the CMOS. To do the latter, disconnect from the wall and display, then remove the CMOS battery, then press and hold down the power button for 30 seconds. Replace the CMOS battery after 30 mins.

Once you're in the OS, might want to see if anything is flagged in Device Manager with an error.

Hi Lutfij,

Thanks for the suggestion!

Tried this today with no success. The flash was successful, I removed the battery for about a minute.

Powered it back on and the PC crashed on the screen that asked me to press F1 to enter setup. Had to pull the plug from the PC again before I could boot into Windows

OK, so you reinstalled windows; from what source, a new iso from the media creation tool? After reinstalling windows, tell us everything else you loaded after that. Did it have problems right after you installed windows or did the problems start after you loaded something else? Also tell us any changes that you made in the bios settings that are not the default settings. Also what speed are you running the ram memory at; default, xmp, etc.

Yeah I made a bootable USB from the Windows media creation tool. The issues start right away, so you know when you are going through the Windows install and it has to restart? I have to pull the power at each point Windows restarts during setup, just to complete the install.

I have reset all the BIOS settings back to default, the only thing I had initially changed was enabling the XMP profiles but that is all gone.

I have the RAM set to auto in the BIOS (this seems to be default) - current speeds is 4800 MHz

There is one bios setting that you could try: if you Enable Virtualization that usually clears the memory on each reboot so maybe that would help. But if the problem persists you will most likely have to return the motherboard.

Yeah that was on, tried turning it off as well, no change. Looks like it will be a return! Thanks the suggestions!
