Messed up PC with graphics card change

Specs: Windows Vista Premium
Hopefully someone can help me on a bit of a problem I am having. I wanted to upgrade my graphics card (was a NVIDIA 8500) so I purchased a NVIDIA 200 GTS to replace it. I needed to buy a new power supply to support the new card (needed an output of 500W, old one was 350W).

I bought the new power supply and installed it. That went okay, the supply worked fine with my old video card and everything seemed to be in order. I received my new card (the 200 GTS) yesterday and stuck it in the slot my old card was in and now I have major issues.

My PC will not boot up and when turned on a beeping error plays. The error seems to be one short beep followed by one long beep, pause, short beep, long beep, pause and so on.

I couldn’t figure out what I had done wrong so I took the new card out and put the old one back in but it still does the same error. It seems like it doesn’t recognize either card at all.

I am hoping I didn’t screw up my pc beyond all hope.

My PC is a HP m91501. I unfortunately can’t give you complete specs because I can’t boot the computer up but here’s what little I do remember;

Windows Vista Premium

Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40 GHz, 2400 Mhz, 4 core(s), 4 logical processors


NVIDIA GeForce 8500 GT 256 MB (old now)

Sorry, I know that’s not much.

Any help would be much appreciated. Thanks so much!

Does the power supply spin up or just come up and go back down? I suspect that when you installed the card you may have simply unseated the power connectors to your mobo. Double check the connectors with your old graphics card which you know has worked.

It could also be a BIOS problem. You BIOS might be plug and play where it auto detected the new card and switch the PCI EXP port to use it. Try resetting you BIOS setting back to factory if all else fails.

Thanks kindly, it was a connection thing, one of my RAM modules was loose.

BUT I have a new issue now, still graphics card related.

I fixed that up and now no more beeps and the PC starts now but my monitor still doesn't recognize any of the grapics cards. Once again I thought it might have only been the new one but neither work. They dont seem to send out a signal. I've double checked the monitor and the monitor cords and they work fine on other computers so I know its got to be related to my PC somehow.

It sounds like my PC is booting up fine now, and all the fans (including the graphics card fan) seem to be working fine but there's just no signal. I dont see any other wires or anything that should be connected to the cards so I'm just confused now.

Ive removed and replaced both cards several times now so I'm pretty sure (unless Im doing something really wrong) it's not a connection issue.

Any suggestions now?

EDIT: I should also mention the NEW card is a NVIDIA 250 GTS and the OLD one is a NVIDIA 8500 GT.

Try a different monitor.

I hope its not true but if this is an older CRT Monitor and you ran it at the wrong sync frequencies it may have damaged it. This is worst case. It is probably something simple as the cord on the other end (the one which connects to the monitor) has come loose or you might have bent a pin in one of the connectors. In any case, by hooking up another monitor you can determine if the problem is in the computer or the monitor.

Second problem might be that your Mobo has an onboard graphics card. If this is the case, hook you monitor into that connector and go into the BIOS and disable it so that it will use your PCI EXP card.

My monitor is a HP w2207. It's an LCD so no CRT problems. I actually tested the monitor and both cords ((I have an HDMI and VGA for backup) and they both worked while hooked up to a separate PC and laptop so I'm pretty sure it's not a monitor problem.

My motherboard does have integrated graphics but I was using a graphics card prior to the upgrade so I don't think it would have switched back to integrated. I will check that though and report back.

EDIT: Okay so the integrated didn't work either but I did see though that when I plug the monitor in to either the integrated or the card the monitor does seem to recognize it's been plugged into something as it comes out of standby for just a couple seconds to say that it's going to sleep and then goes into standby again.
