MSI Z490M New CPU VGA Lighting Activation
Here’s a revised version of your text:
Hey everyone! I’m trying to figure out this computer build. I assembled it using a mix of used and new components. Below, I’ve listed what I used or new. I wanted to install an Intel 11 generation processor, specifically the 11900KF, but realized I needed to update the BIOS for compatibility. I had a 10 generation Celeron on the board, and it worked fine when I booted it up, but I soon discovered the board came from an OriginPC, which meant I couldn’t use the standard MSI BIOS. I reached out to Origin support, who provided a tool to flash a retail BIOS onto the board—this worked perfectly. After updating, I installed my 11 generation I9 KF processor and successfully booted. Then I added the I9-11900KF and tried everything again. My backlit keyboard lights up briefly before going dark, but on the monitor it displays “CPU or Memory has changed click F1 or F2 for whatever action,” which is normal, though my keyboard still won’t respond. I rebooted, and now only a black screen appears, with the VGA light shining in EZ Debug. There’s no “No signal” message, just a completely black display.
I’ve tried several fixes so far:
- Re-seating the processor
- Reconnecting power cables to the motherboard and GPU
- Reseating RAM
- Using a different GPU (GTX 1060)
- Clearing CMOS (touch the pins with a screwdriver for about 10 seconds)
- Testing with another keyboard
- Switching to an HDMI cable instead of DP
- Reinstalling the Celeron to see if it boots
I’m aware that the I9 is KF and lacks an integrated GPU, but during assembly I kept the Celeron in the motherboard slot, using the GPU for display. Do I need specific BIOS settings for these models?
Parts Used:
- MSI Z490M Mobo
- Lenovo RTX 2070 Super NVLINK
- New: I9-11900KF
- Thermaltake 850w Modular
- Fractal Pop Mini
- Artic Freezer II
- Thermaltake Water 3.0 (with GPU bracket)
- GSKill Trident Z CL14 3200MHZ 32GB
- WD Black NVME
Thermaltake 850w Modular is the model in question, with 850W listed as the PSU's rated power. Determine the exact unit model and assess the age of the PSU at this stage. If acquired secondhand, identify the previous power source for the RTX2060.
I replaced the celeron and it restored the defaults, then restarted everything. After checking everything, I tried the 11900 again. The same message appeared: “cpu or memory has changed, press f1 or f2.” I can’t use my keyboard, there’s no lights on, and the mouse isn’t working. Should I consider another BIOS update?
