Precision 7920 Boot Problem
Hi All,
I purchased a used 7920 to replace my current rig (7910) to move on to Windows 11. After getting the machine I put a 4xnvme card in it, installed Win11 and ran DCU to update everything which included a BIOS update. I let it go overnight and shut it down next day without checking the results (it was on the dinning room table and breakfast was being server)! It no longer boots up. Well it turns on but nothing happens, white power light but nothing else. I thought it might be a bad BIOS burn but it doesn't do the BIOS recovery 2, nothing happens when I press CTRL+ESC on power on. I replaced the button battery, still no good. I'm in the process of removing components to see which is being problematic. I removed all the memory sticks and it flashed no memory lights (2amber, 3white or vice versa) so I'm thinking the BIOS is not too coruptted!!!
Any ideas on how to proceed before I tear it down all the way?
TIA,

Hello,
if you are using, by chance, a 4k monitor, try plugging a normal FHD one. Updating the bios may have some quirks with 4k monitors

@RobTinati well, I cannot elaborate in too many details... simply is a known issue reported by a few people. In some circumstances ( bios update for sure, maybe there's another case too ) the post hangs / stops if the screen is 4k. Once the first reboot finalizes things ( having a not 4k monitor plugged ) , then a 4k can be used normally

If mazzinia's suggestion doesn't work, and you can't even access F2 BIOS or F12 Boot Menu, it sounds like your MB really bricked.
Though you replaced the battery, I'd still try a BIOS reset.
A couple of our other Rockstars suggest not updating BIOS thru DCU, Support Assist, or Windows. Instead, download the new BIOS to a blank flash drive. Immediately upon startup, press F12 for the Boot Menu and choose the USB flash drive.

@mazzinia_ Finally got back to this and yes I am using a 4k monitor! I'll try to dig up a HD to see if it makes any difference. I wonder why that would make a difference during POST!!! Can you elaborate...

@mazzinia_ I dug up an older HD monitor and it worked! There is no way I would've thought of the monitor being the issue. You are a superstar and thanx for your help.
