Dell G7 7790 BIOS Update 1.5.1 Broke My Machine

Jump to solution

Updated my G7 laptop today to bios 1.5.1 and now many games when I play the GPU randomly spikes and stays spiked at 100% usage and my fps drops down to like 5fps or less for like a minute, then suddenly goes back to normal for a few minutes.  I didn't install any other updates than that and I also did a system restore just in case to yesterday when things were perfect and didn't fix it so I think it's gotta be the BIOS update.  I also did a clean install of the GeForce drivers and didn't make a difference.  Bad thing is there's no reverting back to the old one, even the auto recovery doesn't work.  What do I do!?  I just got this and now it's pretty much unusable to play games!

I tested through a quick match this morning and didn't have any issues.

*edit - ok it's definitely busted, and definitely from the BIOS after doing extensive testing tonight, I'll PM you, think I'm gonna need a mobo replacement with the old BIOS on it.

I'm having the exact same issue after the update on a G5 5590. This is so frustrating.

Ya this is really frustrating.  I worked with Dell on the phone again yesterday, and I ended up doing a clean Win10 install using Microsoft's Media Creation Tool and installed nothing but a couple games and it still did it so it's 100% caused by the BIOS.  The tech said replacing the mobo probably wouldn't fix it as likely they will all have the latest BIOS so he said to wait for a fix.  Told him no that's not an option, I need a refund then and he said it's been over 60 days so can't. Told him I'd just quit paying the payments on it then and never pay for it as I'm not paying for something broken.  It's been escalated to the product team so we'll see what happens.  Here are a couple videos of the issue in action

and some screenshots that include fps and GPU/CPU usage, notice when it happens the CPU is very low usage and GPU is spiked

Installed Win10 Pro fresh from Microsoft and the game only and still happening, it dropped to 5fps for quite a long time then suddenly went back to 80+ fps.
Laptop worked great for weeks until I updated to BIOS 1.5.1 yesterday and now every game does this randomly while playing. Went as far as doing a full system reset back to Dell default Windows 10 install and still doing it so definitely the BIOS update that caused this. Temps and fans seem the ...

Yah this is exactly what I'm experiencing too. It does that every 4 - 5 mins and last around 20-30 secs each time. I have Alienware Command Center open so I can see the GPU clock suddenly drops to 300mhz and stay there for 20-30 secs. I was only 5-6 mins into gaming so it's not thermal it's completely because of the new BIOS update. The quickest fix would be allowing us to revert back to 1.5.0. I have similar specs on my G5 ( i7 7850H / RTX 2060 ) so maybe it's why we both have this issue?

Yep mine lasts the same time and the odd thing is sometimes I can play something for like 2 hours before it happens, but then once it happens it does it every few min for 20-30 secs at a time.  There are no errors in event viewer so it's not like the display driver crashing/recovering as I've seen in the past.  And I did a fresh Win10 install from thumb drive and installed nothing but the GeForce drivers and my games still did it so it's 100% caused by the BIOS.  They better either put out a way to revert or a new BIOS within a few days or replace the laptop with one with an older BIOS else or something because this is such bs.

Is there a program that shows a chart of the GPU clocks ? If there was one you would definitely the GPU clocks spike and dive occasionally. Yeah sometimes it would be able to play for 30 mins or so without any issues, but once it happens it does it every 4 - 5 mins so all the games are just unplayable.

Maybe it's the same story for all G3/G5/G7 2019 owners with 1.5.1 bios?
