Graphics card problem

[WiiUMasterGman]

Ok. I have made 2 threads about this but I want to have some new eyes on this. I have a friend that wants to buy a new graphics card. He is cheap so I said to buy a refurbished R7 240 or 250. I tried to install my graphics card to his computer. Didn't work. I uninstalled his drivers and disabled his Intel Graphics I got to the point where it powered but not on with my graphics card displaying anything. I used his motherboard for display. Something happened (HOLY COW DID I GET EXCITED!) but it said I needed to go to Windows recovery feature. I didn't have to to go any further because he had to play in a CS:GO tournament. I am going to go back in about a week. I feel like I wasn't supposed to disable his Intel graphics and boot with my graphics card put in but boot connected to my HDMI cable connected to the motherboard. I can't get into the BIOS and I don't know how to because I don't have the option too. What are your thoughts? What should I do?

You should never need to disable the onboard graphics, simply put in the new card and connect the monitor cable to the card.
If an add-in graphics card is working, the onboard connectors should be disabled.

To get out of your current issue:
- Remove any discrete graphics card and connect the monitor cable to the motherboard video outputs
- If you don't get any output, shut down the PC and disconnect power, remove the CMOS battery on the motherboard and hold the power button in for 1 minute, replace the battery and boot

An alternative:
- Install a graphics card and connect the monitor cable to the graphics card

Ok, after I remove his graphics card and put in mine boot off of the motherboard graphics then what? I have never had to remove a CMOS battery so how would I do that. Any concerns I should have? your alternative wouldn't work because my graphics card doesn't give any display

Remove ANY graphics card. If any discrete graphics card is installed then the integrated graphics will be disabled.
The CMOS battery is flat and shiny. You can lift it out gently.
By disconnecting power, removing the battery and holding the power button it will lose all settings in the BIOS. The default settings should reenable integrated graphics.

Once you have the PC working on integrated graphics, then you can worry about getting a graphics card working.
Install a graphics card (with the power off), connect the monitor to the graphics card and power on. If this doesn't work, don't play in the BIOS to try and fix it. Instead check that the monitor cable is connected, that PCI-E power is connected to the card if required and that the correct input is selected on the monitor. Use a graphics card that you know works in another machine.

There is no power connector on my card. I also don't know how to get into the bios because I don't have the option too on startup.

So this is what you want me to do
1. Uninstall the drivers for the GT 620 and remove it after.
2. Install my graphics card and use the HDMI connector on my graphics card. But this won't work because my graphics card won't display anything.
3. Boot

This is what I thought would work.
1. Uninstall his drivers and the GT620
2. Put in my graphics card and boot using motherboard output.
3. Restart
4. Hopefully the HD 7750 will show up. I think this will work because when I restarted with his graphics his GT 620 didn't show up. I then restarted again and the GT 620 showed up

You said "I feel like I wasn't supposed to disable his Intel graphics". How did you do this if not in the BIOS?
Where did I mention "HDMI connector on my graphics card"? I'm suggesting you boot with no graphics card installed.

It really isn't hard. If you haven't been playing in the BIOS then it should work with no graphics card installed simply by connecting the monitor cable to the video output on the motherboard.
Once you have that working, inserting a graphics card (with the power off) will disable integrated graphics and you connect the monitor cable to the video output on the graphics card.

You also mention cards "showing up". I thought your problem was getting a video output from the PC.
Once you have video output, you need to go into Windows and install the correct driver suite from Nvidia (for the GT 620) or AMD (for the HD 7750).

Note also that a GT 620 is a very low end card, likely no better than the integrated graphics.

I disabled the integrated graphics in windows before I put in my GPU.

Ok so when I installed his GPU when I was done his GPU didn't show up in device manager. I restarted then his GPU showed up then I installed his drivers again then left.

Right, well don't do that again.
If Windows is the only issue, simply boot in safe mode and enable the integrated graphics again or if that doesn't work then go back to a restore point.

How do I boot into safe mode? When I start his computer it just goes to Dell then shows windows that's it
