Nvidia card swap results in no booting

Rankio · 01-14-2006, 05:31 PM

I had a Nvidia 6800 128meg OC in my machine til my brother upgraded and let me take his 6800 GT 256meg. After installing the new card and turning the power on to my machine, nothing happened. I took the card out and put it back in and checked all connections and the machine now took power but nothing else would happen. Retrying the same method gave the same results.

So then I tried putting in my old GeForce 4 card (my 6800 OC is at my brother's house now) and the same thing happens. Power but no booting, no VGA signal, nothing.

Any suggestions are appreciated.

Specs:

P4 2.8ghz
2gigs RAM
P4C800-E mobo
380w PS
2 IDE HDDs
2 DVD-ROM drives

most likely underpowered

I would guess that also but why would the same problem happen when I put in my GeForce 4?

I'm not sure how much more power a GeForce 6800 GT needs over a GeForce 6800 OC but I never ran into a power problem before.

Does your mobo have onboard video? If so maybe it switched over to it.

No onboard video (don't we have the same mobo?). Would it matter what type of monitor I have hooked up? But I do not think I am booting into windows. I tried making an autoplay CD with drivers on it but it wouldn't run. The drives would spin reading the disk but no other actions happened, i.e. autoplaying the EXE.

Yea we do didnt see that. Ok on to the next thing. Do you have the post reporter set to enable in Bios, if so does it say anything.

Asus boards are funny about hardware changes, try clearing the Bios with the CMOS CLR Jumper, unplug PC before doing that.

Ok I cleared the BIOS and have my old card in (GeForce 6800 OC). The computer powers on, everything runs but no VGA signal.

Well isn't that convenient, I did not know about that.

"system failed cpu check" is what i hear. Now this could be a bad or improperly installed CPU or maybe the CPU fan isnt working or your Powersupply is faulty.

The PSU at 380 watts is not much since the efficiency may degrade it down to as little as 320 or less if it is weak.

I know it seems that this happened when you switched cards but this may have just pushed the PSU over the edge. Try a stronger PSU, Antec or Enermax at 450 or greater watts is what most of the Tech guys here recommend.

Thanks alot for your help. I'll order a new PSU and see if that helps. If not, looks like a major upgrade is due. Thanks again.
