Can bad graphics card (blown capacitors) kill MoBo?

Hello,

All 10 capacitors on a cheapo graphics card exploded. I tried to restart the computer quite a lot before I found that this was the problem.

So I bought another graphics card but now the computer hangs on the splash screen.

I tried about everything I can think of: only one (known good) RAM stick, another known good RAM stick, disconnected all drives, reset the CMOS, left the battery off for hours, different PSU.

Nothing helps. the PC starts, shows the splash screen, (hitting Del gets as far as the message: entering setup) and than it freezes.

My main question is, can the blown capacitors on the graphics card kill the MoBo (ASUS P5N-D)?

  1. Try another PSU before you blow the rest of it up. Most likely your PSU blew up the capacitors on the vid card.
  2. Yes, the death of the video card could have taken the motherboard with it. What make/model of video card were you using?

    This is good advice as well. A defective PSU can certainly damage a lot of stuff.
  4. 10 caps?! wow. never heard of such a thing

    Power surge? Lightening strike? I agree, this is pretty unusual.
  6. The video card was a no-name e-GeForce 7300 GT 512MB DDR. I paid something like 29 bucks for it..

    I tried another PSU (after the graphics card blew up). Doesn't help-the PC freezes on the splash screen.

    So it looks I also blew my MoBo? grrrrrrr!

    No power surge - the PC is connected to a pretty good UPS (APC Smart-UPS 3000).
    I found that these are the bad capacitors that blow. http://en.wikipedia.org/wiki/Capacitor_plague They blew all at the same time - sounded like firecracker. :ouch:

    Understood, but that is dang odd nonetheless. You should post a picture if you still have the GPU.
  9. I have replaced alot of capacitors on motherboards back in the day, but not on video cards. It is possible that it may have taken your motherboard when they failed.

    I was wrong - only(!) 6 out of 10 blew. (the bigger ones 1500 uF - 6.3V)

    Here's a pic - sorry for the bad quality.

    It looks like it, yes. Nothing that I do can get the motherboard beyond the splash screen.

    Yeah, I don't really mind the GPU but the motherboard I do mind..
  14. damn, thanks for the pic dude. nerd porn to be sure. sorry for your troubles mate

    You may have already tried this, but does safe mode load???If so uninstall the drivers and try to boot in normal and reload video driver. Also boot with Linux cd and see what is up. you may need to pull the drive and run chkdsk on another pc on your drive. a few times when this happens I have seen windows get corrupt from the sudden loss of power. Good luck.

    +1 Agree, Try save mode first or low resolution mode (vga mode) first.... see if it can get into OS... (it might be driver issue)
  18. @ thillntn & rdc85: if it would start loading the OS I would be happy and get it running. The problem is that it doesn't even load the BIOS data..

    I used an Ultra and a Corsair. Both PSUs work fine in other machines.

    It really does appear to be a defective mobo at this point.

  22. Thanks everybody - time to go shopping for a motherboard I guess..
  23. Awesome pic.
  24. For those of you who like the pic, here's a close up of four of the blown caps. (click the pic for a larger size)

  25. I'm wonder what it smells like (the solid capacitor)

    The elco ones smell like roasted peanut ... :D

    Anyway It sad to heard that your mobo died...
