Why is the internal (integrated) video card not working?

Question

Computers

There is a personal computer:
motherboard msi b85-g41 pc mate
processor intel xeon e3-1241 v3
RAM ddr3 2 bars of 8 GB

This processor has a graphics core, and the motherboard supports an integrated video card.
Initially, when I purchased this computer, I used it without a discrete graphics card. Then, for experimental purposes, I installed a discrete graphics card from my old computer, and used it for a couple of years.
Now this discrete graphics card is making noise due to the cooler, and as it turns out, it is less powerful than the integrated card. I want to start using the internal video card again, but nothing comes of it. How I tried to do it:

1. The very first thing that comes to mind is just to get it out of the mat. board a discrete video card, and insert the vga or hdmi cable from the monitor into the motherboard connector. But in this case, when I start the PC, the monitor writes that there is no signal.
2. Enable the initialization of the internal video card in the BIOS, not the discrete one. I found this option in the BIOS, where there are 2 parameters - PEG and IGD. I put IGD, I press save and restart, the discrete video card still works. I'll log into the BIOS and see that the value of PEG is again worth it. I put IGD again, click save BIOS settings, turn off the computer, take out a discrete video card and insert the monitor cord into the internal one, start the computer and still the monitor writes that there is no signal.
3. I tried to do all of the above using VGA and HDMI interfaces, you never know what worked. No result.
4. I tried to update the BIOS to the newest one. Nothing helped either.
5. I took out the battery from the mat. boards, inserted a jumper to reset the BIOS. Didn't work.

How to solve this problem? How to enable the internal video card? I've used it before and it worked great.

Answer 1

The intel xeon e3-1241 v3 processor does not have onboard video. Xeon processors that have an integrated graphics card are called e3-12x5 (have a "5" at the end of the model number) Example
