MSI Lightning R9 290x -- No signal, please help! Tried everything I could..

Hi,
I have a MSI Lightning R9 290x that failed on me last month and after hours of troubleshooting I still can't find where does the problem come from. The card seems to boot fine but doesn't output any signal from either DVIs or HDMI.

So what I did so far:
- Tried it on a different setup, with plenty of power
- Updated drivers, tried different ones
- Flashed the bios
- Tried it in a mining rig (gpu riser)
- Looked for a blown cap/res/mosfet
- Even tried the baking method

The components look ok but it looks like there was a spark in the VDDCI test socket (see pictures). I guess a short-circuit occurred somewhere on the board..

Also, I found that all the small caps at the output side of the VRMs (see picture below) are shorted to ground or at least have very low DC resistance (3-4 ohms). I tested them in-circuit so it could be something else also.

I'd really like to get this card back to life! Any idea will be appreciated. Thanks in advance.

  1. After all your good troubleshooting , seems like it died.

    2 MACHINES with no life in the card , means it has died , great job troubleshooting.

  2. In all honesty, there is likely no way to bring the card back to life. Based on what you described, you likely damaged some component that was responsible for graphical output. Unless you have a blueprint of the card and are extremely proficient with both a soldering iron and a voltage meter, your best bet would be to find another card. I'm not sure that it could be repaired even with those skills, sadly.

  3. Yup. Dead card. If you tried it in another machine and even put it in your oven and it didn't come back then I would think the card is shot. They don't last forever. More so if it's a higher end one.

  4. marc.antoine.lavoie I'm sorry to hear about your 290X. Just out of my own curiosity, would you mind listing your full specs, including your power supply's manufacturer and model number? Again, really sorry for your loss. What GPU would you consider replacing it with?

    Hi there, I can't recall my full system specs in detail (at work now) but here's what know:
    - PSU: Corsair Bronze 650W (non-modular), also tried with a brand new Corsair Gold 850W
    - MB: Asus Z97M with LGA1150 socket
    - CPU: i7 4790k

    Like others said, the card is most likely fried up.. I just wanted to make sure I tried everything before selling it for parts. I already have a spare 290x for now.. Thanks everyone.

    You covered all the bases it's most likely fried.

  7. SR-71 I agree with your original response, that it's fried. I was curious about the specs because the dead GPU seems like a result and not the cause. I'm proposing that marc consider only using the new Corsair gold 850w, instead of the Corsair Bronze 650W (non-modular). My fear is that the older PSU may have killed his GPU slowly over time.

  8. 850W? Most PCs use 300-400W.

    Edit: I know he was using a 300W GPU and his draw was closer to 450 and not 300W. But he could pop a 1060 or a similar card and drop down to the 300W range. 850W are really for multi GPU system which he hasn't talked about.

  9. I doubt it was the older Corsair that cause the fail.
