Hi guys,

It's been quite a while since I logged on.
I hope that everyone is doing well.

I have a problem and I am hoping one of the HWA'ers can help me with it.

I recently bought a Diamond HD Radeon 4890 from newegg.
It was on sale and I got a good deal out of it.

There was small problem with it, though. There was a constant rattling fan noise.
The sound was very annoying. I thought about getting a cooler.

Then I found a guide that someone posted on some forums.
He explained how you could get rid of the sound.

I followed the guide and viola...no more rattling fan.

BUT..a bigger problem occurred. When I turned my PC on, I got a white screen with vertical lines.
I cannot see POST info or anything...but I think the PC loads into Windows 7 just fine.

Here is the screen:

I searched around...I tried a few things...
I disassemble the card 3 or 4 times...I tried to clean the board.
I tried resetting my CMOS...all of that did not work.

The only solution left to do is to bake the board...
I am not kidding...some people are reporting that it actually worked for them.
Look it up on youtube.

I think the card is dead...so...I am not losing anything here, right?

You should know that the PC is running just fine with my old 6800GT.
This should rule out the power supply, the ram and motherboard.

I am posting this to check with you guys if you think that there are other possible solutions
before I go ahead with baking the board.

.
Without knowing exactly what you did to resolve the fan noise problem, it's shooting in the dark...but some other things to consider:

1) Did you power off the PSU before removing/installing the video card and its auxiliary power connectors? If not, the card can be permanently damaged. (that means NOT just using the front panel system "power" button, but either using the PSU rear power switch and/or unplugging the PSU from AC mains and waiting a minute for residual power stored in the PSU to bleed-off.)

2) Did you use ESD handling protocols while working on the board every time and at all times? If you didn't you could have permanently damaged modules on the board (e.g. RAM, GPU, etc)

3) Have you tried other video output connectors on the card and do you see the same or different symptoms? (I'm going to assume your test with the 6800GT was done with the same display AND the same video cable AND/OR cable adapter. I they weren't that's something to check as well...coincidences do happen)

4) Is the video card recognized by the system (e.g. does it show up correctly in control panel, etc.)? This obviously requires using a secondary video adapter (either motherboard or PCI). Or...you can try plugging the suspect video card into a different PC and seeing if it "sees" the card properly (since your report strongly suggests the suspect video card apparently hasn't damaged your original PC because the PC still worked with the 6800GT card).

5) Did you make sure all auxiliary power connectors were connected? (I know...it's a basic question but sometimes people do forget this...and again, ALL handling of the card must be done with PSU power removed)


edit: to clarify how to verify PC properly recogs suspect video card in item 4.

Is the fan actually working?

The chip is damaged and baking MAY work, it may not. If there is no warranty on it, then go ahead and try it. Even if it does work - it will probably not last long.

I am assuming you applied new thermal paste when installing the HSF? Did the ram chips have thermal pads on them?

When/if you pull it apart again, check the entire board for damaged components.

And try what John said about using another output on the card too

Hi John,

Thank you very much for the points you mentioned.

Unfortunately, I am pretty sure I did not follow any ESD handling protocols.
So, that could be the reason behind the damage.

I took your idea and booted into windows with a different card while the 4890 was plugged as well.
The MB has two PCI-E slots. Sadly, the card is not recognized by Windows 7.

I think I will go ahead with the baking idea.

Thanks for your reply.

Hey Double,

Yes, the fan is working and the 3 red flashing lights indicates there are no problems.
(There are 3 LEDs that flash on boot up. I read that if the lights stay on, that means there is a problem.
In my case they don't...actually that was a big part in me believing the card is not dead.)

Yes, I did apply new thermal paste, but that was not done after the first re-assembly.
I did that the second time I dissembled the sink.

The RAMs do have some padding. I don't think there is a problem there.
The padding is sitting where it is supposed to be.

I did check the board for damaged parts...I did not see any broken/damaged parts.

I know the baking idea is not a definite cure..but I have nothing to lose.
I do have warranty on the card, but I live in Saudi Arabia. My brother bought the card for
me while he was in the US. I spotted the Newegg offer for the card. It was selling for $70.

I asked him to buy it and he did. If I wanted to take advantage of the warranty,
I would probably end up with a great shipping cost. That's why I chose to handle
the rattling fan on my own.

Thanks for the support. I will let you know if I get lucky with the baking thing.

See you around. ;)
