Fried 9800 pro?

[imported_ninex]

CLIFF NOTES: bought 9800 pro with r360 samsung chips, flashed to 9800xt, card died, trying to figure out if i can reflash it back to 9800 pro or if it is dead

During the summer I purchased a BBA ATI Radeon 9800 Pro from another ATer. It came with an R360 core, with Samsung memory (I'm fairly sure). The previous owner had already installed an Arctic Cooling VGA Silencer 3 on the card, along with AS 5. Shortly after I got it, I decided to flash it to a 9800XT, which I did successfully.

After I flashed it, I never noticed any artifacts, and never OCed it past the default XT speeds except when doing an occasional benchmark. Never while playing any games and/or benchmarking did I notice any artifacts, and it always seemed to run fine. After moving back into my apartment during August, I set my computer up and had it running. About 10 minutes after it had been running, my monitor just shut off and wouldn't come back on. I rebooted and everything, but couldn't POST. All the fans would spin up as usual, hard drive turning on, but I couldn't post. It was obviously my video card.

I figured all I needed to do was to reflash the BIOS back to a 9800 pro and things would be fine, so I did everything I knew how at the time to try and do that. I read on AT that putting a PCI video card in my computer would allow me to boot up and flash the AGP 9800 pro that I had. I got my dad's pci card, but my computer still wouldn't POST when I had both cards in there. It would work fine with just the PCI card, but not both. Eventually I gave up and purchased a 6800GT from Best Buy, which worked fine.

About a week after I bought the card, I ran into some financial problems so I decided to take the card back, since I wasn't playing many PC games at the time. I kinda gave up on the situation, since my laptop was working fine and I was doing all my gaming on my xbox, since I recently modded it. Now that HL2 is coming out soon, and I just miss having my desktop, I'm gonna try fixing my video card again. If anybody could give me some help on what they think is wrong, I would grealy appreciate it. Maybe I'm doing something wrong with the PCI card, maybe the card is dead, I dunno. Any help would be awesome.

Thanks in advance.

I dont know the wierd thing is that the same thing happneed to me with my 9800pro not to long ago. I didnt flash my 9800pro tho but i over clocked to 420/375. I only installed an Arctic Cooler Rev 2. I have a feeling that i fried my ram becaue there was no cooling on it. Just randomlly while playing a game my screen also went black, but i have been running those speed for like a year. I put in my friends mx 4 and things worked fine. I just replaced with a eVGA 6800GT becaue my warranty fro my 9800pro was more than a year old. If anyone could i guess solve our problems that would be so helpful beauce i would have a working 9800 pro again.

It is possible to flash it back to the original 9800 Pro BIOS. That is, if you made a backup of the original BIOS you could. You did back it up, right?

BTW, when the card is plugged in, does the the hsf go on? I had to kind of wiggle mine in my card before it really made contact the first time I installed it.

All the best and good luck.

Yes, I backed up the original BIOS. My main question is how to flash it back. I mean, I know how to flash it, but whenever the 9800 pro is in my computer my computer won't POST. Even when I have a PCI card in with the monitor cable hooked to the PCI slot, it won't post. I'm assuming that I need the 9800 pro in the computer to flash it, right?

I'm not sure if the hsf turns on or not, I'll check it later today.

He'd have to get it to boot first.

This may be the dumbest thing i'd ever say, but here goes:
What if you remove the 9800p, then boot up with the PCI card, then insert the 9800p? Worth a try, no?

EDIT: DO NOT TRY THIS (SEE MATTHIAS'S POST BELOW)

Don't do that! You can't hot-swap AGP cards, and are risking even more serious damage than it may already have.

Bump for anymore suggestions.

Yeah I would never stick my hands inside my case when my comp was running... unless, of course, you have a death wish...

 

[imported_hopeless]

I thought I read that it will boot with just the pci in it. Did you check the BIOS to see if you have an option of having the pci over agp. With both cards installed it may still be trying to use the pro.

 

[chowmein]

i think its probably fried, did you try using ur dad's machine?

somewhere in your bios you should have a choice of video setting AGP/PCI or PCI/AGP, hard to say cause each motherboard is a tad diffrent, if you do have this option youll probly have to set it to PCI/AGP in order for it to boot to the PCI card with the AGP installed too, but im not sure i dont have any pci cardz <shrug>
