PC no longer recognizing any video cards. Did I damage my PCIe slot somehow?

I recently ordered the Sapphire R7 265, and after plugging it in and hooking up the power supply, I got a black screen. After removing the new card, I placed my old HD 6670 back into the PCIe slot, only to find it to is giving me a black screen.

I went as far as unplugging everything, completely removing my mobo to make sure it is seated on the risers, turning off onboard video if a PCIe device is detected, making sure my BIOS is up to date, and uninstalling the onboard video drivers, and attempting to install the ATI Catalyst center.

I am currently plugged directly into the motherboard, and outside of it not detecting the cards, everything seems to be in working order.

I have yet to test the new card in a friends PC, but seeing as my old card isn't working either, I don't think my issue is a dead card.

My mobo is a Gigabyte GA-M68MT-S2 , and I have not tried resetting the CMOS. I will try that once I am home.

I did try reusing my original graphics card, and still got a black screen. The fans spun in both cases, I wasn't getting any sort of beep errors.

Removing the original graphics card did take quite a bit of effort, I'm hoping I didn't physically damage the slot.

So you have just the one PCI-e X16 slot, so that rules out trying another slot.

You said that it took a lot of force to remove the old card. I am also hoping you didn't damage the slot. Did you release the latch at the back of the slot while removing the card?

Give the CMOS reset a try. Hopefully that will work for you.

I did release the latch, but it still took a lot of elbow grease to get it out. There is now noticeable slack when inserting the old or new card now, it doesn't take a lot for it to come out.

Have you tried the CMOS reset?

Have you inspected the slot carefully? I would get in there with a flashlight and see if you can see anything wrong. Typically the more you insert and extract cards from the slot, the "sloppier" they'll get. However I don't think it should be a drastic change like you are describing.

Reset the CMOS, no dice. I at least did something so that it now recognizes the old card.

One weird thing, I was able to get the new card recognized ONCE in safe mode. I am beginning to think it is my PSU. I currently have a 480w nameless PSU, and the card calls for at least a 500w PSU.

So resetting the CMOS got your old card working? Well at least that's a leg up.

Can you try your new card in another system? A friends perhaps?

If you have a no-name power supply and it's below the suggested wattage, that certainly could be the issue.

Can you give your entire system specs, CPU, RAM, motherboard, hard drive(s), etc. This way we can give you an idea of what you need and some suggestions on manufacturer.

I have a great problem with my radon 6570 HD Pci ex card. when i can not use my pc more than 10 to 14 hours and after it when start my pc no display found with my pcix radon 6570 graphics card. then I unplug my vga cable from pcix card port to onboard vga port then it shows display. after restarting pc no display found to onboard but connection goes to my pcix graphics card. this alteration ( connection from onboard graphics to pcix graphics) occurs at initial stage. But now my pcix card always shows no output. but connection always stablished to my onboard vga port. I use my pcix graphics card to another pc and it works well. Whats the problem it is? my pcix card fan works well. where the problem generate? my bios setting is ok.

Well normally it's not recommended to hijack an old thread. It's recommended to start your own thread.

However I'll give you something to check in the meantime. Go into your BIOS, there should be an option for Initializing Graphics. Set it to PEG or Discrete (depends on the BIOS), this will tell your computer to attempt to initialize your graphics card first.
