Windows 7: Onboard video not working after trying new video card

Onboard video not working after trying new video card

I bought a new msi gt 620 video card and plugged it into my pci 2.0 slot, fan started spinning up, and my monitor gave the message no signal. So I removed the card and plugged the dvi cable back into the mobo graphics, which I have been using to this point, and again got the no signal message. Nothing is showing up the bios or the os. I moved my monitor to a different computer and it works great. Is it possible the new video card messed up my motherboard? And how would I test that cause I don't want my other computer to stop working too lol

First, let's see if we can get your video back.

Remove the new card and connect the monitor to the on board video, then perform a ClearCMOS procedure. Check your motherboard manual for the procedure (CLRTC is the same thing).
All but the newest boards do it like so:
  • Shut down the computer > remove the power cord.
  • Remove the 3v battery.
  • Move the CLRTC jumper from pins 1-2 to 2-3.
  • Touch a metal part of the case and Press and Hold the reset button for approx. 30 seconds to discharge all power from the board.
  • Put the CLRTC jumper back on pins 1-2.
  • Replace the 3v battery > replace the power cord > boot.
  • Immediately go into BIOS and reset all your preferred settings. If the CLRTC worked you will need to reset the date and time.

Tried this and still no go. Also tried disconnecting everything so it was just the cpu and it was a no go and also tried reseating the cpu but I still didn't get any video or post beep, is the mobo likely dead?

It certainly sounds like it. I just can't get my head around the idea that a video card would do that. I definitely wouldn't want to test that theory with that card on my machine though.

So, with only the CPU installed you are not getting any error beeps or codes? Nothing?

This just occurred to me:
Try removing the motherboard from the case and then trying the CPU only. It should give a beep code that means "there is no RAM installed" (duh).
I'm thinking that installing the card initiated a short circuit of some sort.
It is also possible that the board cracked on installation. Neither would be your fault - it would be a latent condition waiting for a victim.

So I tried removing the ram and just starting up the mobo and cpu and got the error messages beeps. Then I replaced everything one by one, including the video card, and now it is all up and running. Great learning experiencing taking everything apart and putting it together one thing at a time, but I am still not sure what happened? haha

Good to hear it.

Sometimes there can be something in the slot that interferes with conductivity or causes some weird short circuit. Lint, even a hair can do it. Re-seating the card can often overcome that.

Sometimes the computer gods are just angry and they just want to see you sweat!
