Computer won’t display at all after putting GPU in

[NdMk2o1o]

Haven't seen anything about going into the bios and switching from on board video output to dedicated video card mentioned in any of these posts. Start from CPU video. Go to bios switch display signal. Save. Shut down. Switch display cable to card. Boot. If display works. Ddu the video driver and re install. Reboot. Worth a shot.

That's because he can't get into his bios....

Unfortunately he can't get to bios.

My bad. Read it wrong. Half way into first coffee of the day.. Hmmmmm.
My old z77 gigabyte board did this and it turned out the pcie x16 slot was bad. Had to rma. I have to agree the board may be pooched. Bummer.

PC's are weird. Pull the motherboard. Remove the cmos battery and let it sit overnight. Test for post outside the case on a peice of cardboard.

What do you mean by “test for post“

 

[NdMk2o1o]

What do you mean by “test for post“

turn it on and see if you can see the post screen, the first thing you see before you boot into windows and that lets you access the bios.

Okay thanks I’ll try that tonight

So what he was saying basically was to strip the PC down, install the PSU, CPU, GPU, RAM and only essential components (I think I covered them all) outside of the case on a piece of cardboard (to protect from static discharge) just to see if it will power on and post with nothing else connected and taken out of the equation. You'd be surprised, I was having issues with my build at one time I couldn't for the life of me get it to startup and post and I literally unplugged everything apart from the essentials, turned it on and voila, it posted, reconnected everything back in the case and the problem was gone so yea just sometimes it helps to go back to basics tear it all down and start again I'd rather do that before I spent money on a component I didn't really need..

Confirming @NdMk2o1o exactly what I mean minus GPU using onboard graphics. Then if you get post, try the GPU. But @Bonkirz leave it sit for a long time not plugged in and no cmos battery. Then if it posts, try with your boot drive hooked up.

Going forward, 1st a couple of things to make life easier in the future.

1. If you click on "system specs" under any posters avatar you will see a list of the components used in your build. I'd fill that in on your profile page so those trying to respond will be aware of what's in the box.

2. Budget is an issue in most builds but a few extra bucks can go a long way, on next build, consider ....

a) Most boards under $120 will come with LAN and Sound systems that most would consider 'substandard' for a gaming build.
b) I recommend setting a budget that addresses a) above and b) would be having a LCD MoBo mounted or at least LED light for troubleshooting purposes
c) Budget MoBos often lack troubleshooting procedures in their manuals.... manually generally runs under 40 or so pages.

3. Make sure you have the manual

https://dlcdnets.asus.com/pub/ASUS/...146.147511534.1554672235-452050169.1554672235
https://www.asus.com/us/Motherboards/PRIME-B450M-A/HelpDesk_Manual/l

Now onto your issue ...

1. One of the most common errors when installing a new card is the cabling:

a) Make sure to use the monitor's OSD (on screen display) to use the correct port. If using HDMI cable, make sure HDMI is selected on OSD.
b) Make sure you have cable plugged into the correct port at the PC....
- i) MoBo I/O panel to use IGP (VGA, HDMI, DVI-D) on MoBo
- ii) GFX Card (typically HDMI, DP and DL-DVI-D) on AIB card

2. Make sure you still have the 8 pin EPS cable for CPU connected after installing GFX card

3. Make sure the 6 / 8 pin power cable is connected to GFX card and PSU.

4. Make sure you didn't dislodge the CPU fan cable during installation

5. Those are the most common, but if those are all OK, remove and replace all cables at both ends.

6. See step (green circle) on page 1-3 of your manual.

7. Make sure RAM is in correct slots ... see page 1-9 of the manual

If that brings no resolution, contact Asus Tech Support by phone ... see last page in manual.

I have a problem with my PC

So my friend got a used graphics card that he bought on offer up which was the rx570 he let me borrow it because I needed a GPU because I was running my pc off my CPU which was the ryzen 3 2200G the same day I was using my PC very well everything worked when I plugged in the GPU my monitor was black so I shut down everything and removed the GPU so I can run the PC off my CPU again and the same thing happened my monitor was black everything works my fan sound but it just won’t display I tried using HDMI port and VGA post and nothing I removed the battery from my motherboard and inserting it again and rebuilt the pc and still nothing and when I plug in my keyboard my keyboard blinks then turns off

So if someone could help me fix this it will mean everything to me thanks

Offer up hmm, does he still have the link?

Probably bios bricked or used for mining.

Take pictures of the White Stickers on the back of the card, they could be on the heatsink. Post them here.

Hook monitor up to the motherboard IGP, plug video card in, take a gpu-Z screenshot. Post it here.

Take a picture of the card front, back, and pcie bracket and post it here.

Take the heatsink off the card and clean the thermal compound off the gpu die and heatsink. Take a clear picture of the gpu die, all of the ram chips surrounding the gpu die and take a clear picture of one of the ram chips on the card.

Reapply thermal compound to the gpu die.

Clean motherboard pcie slot out with systen turned off and power supply unplugged using Electronic Grade Contact cleaner.

Inspect the pcie edge pins on the card, clean them using a rubber eraser and contact cleaner.

I left it there for one whole day I plugged everything in except for the GPU and nothing posted I’m thinking of buying a new motherboard

It does seem that is necessary.

I'm hoping the card didn't kill the board somehow.
I'm saying that because from what I'm reading, the point of trouble began right when he had plugged the card in and powered up.

I just ordered a new motherboard I will be testing it to see if it would work and I won’t be plugging in the GPU lol

Stop what you are doing, dont waste money.

Boot the system from the 2200G IGP, either hdmi, dp, dvi, vga from motherboard io shield where usb ports on back of case are, to monitor.

 

[27MaD]

Power your PC using the IGP and go to the BIOS and check the UEFI , Legacy mode thing.

That would only stop it from showing the post and bios screen, it would still boot up into windows

It didn’t let me boot from my CPU

 

[eidairaman1]

Clear cmos, plug monitor into where the usb ports are, there should be a hdmi, display port, or dvi, vga.

Remove the gpu for now.

If you are unsure go to a shop or watch some youtube videos.

My new motherboard came In today and My PC is now working how it was before thanks to everyone that helped me through this.once again thanks!
