This is my pc,

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01242624&lang=en&cc=us&contentType=SupportFAQ&prodSeriesId=3550541

however I upgraded the RAM a couple of years ago and now run 6gb.

My first problem came on only a couple of weeks ago. It was working 100% fine then all of a sudden I got a blue screen "Windows has failed to start up and has shutdown to protect your system"

This was stuck in a continuous loop of start up repair etc. so I formatted HD and installed Vista 64bit.

I read up on various forums about it maybe being a faulty graphics card, so I removed it from the mobo.

The computer then worked perfect with no faults.

I then bought a used Nvidia GeForce 9800gt and a brand new 750 coolermaster PSU to suit.

On start up it went straight onto a Black screen with blue spots and keeps trying to restart flashing up the blue screen again "Attempt to reset display driver timeout failed"

I restarted in safe mode and downloaded the latest driver from GeForce which hasn't helped. I've reset BIOS, updated chipset, updated mobo drivers, removed battery on mobo for 5 mins and it hasn't changed anything.

It still fails to run. I disabled the card via Device Manager and the pc works 100% fine.

I am wondering if I have bought a dud graphics card or I have another problem.

Should I chance more money and buy a brand new GPU?

Please help! thanks in advance

Have you tried reseating the card and ram yet? Also, remove and reconnect the power connector to the 9800GT. Either a loose connection to the motherboard slots or power connector could cause this as well as a bad video card.

Odd that your mobo video card (I'm assuming this is how you disabled the graphics card in 'Device Manager' works alongside your video card. Usually it's disabled automatically upon booting up and recognizing a card in your PCIe slot. I would try disabling onboard video in bios as well.

Yeah I removed the card and used an eraser on the contacts and with the ram also. I cleaned it out whilst I was in there.

I disabled the GeForce 9800 card via device manager and was fine whilst I updated the driver. Then when it failed I removed the card from the mobo and plugged my monitor into the bottom socket. The pc then simply runs the standard onboard device.

I did double check all of the connections when I swapped out the PSU for the cooler master.

It's so frustrating that I've spend £100 and it's still not working :/

As soon as the GeForce card is fitted It shows Black screen with blue spots then I get the Blue screen with the error before I can enter bios or windows. I eventually get a prompt screen which gives me the option to run safe mode (which again is working 100%)

I never run any games on it, only watch HD movies etc.

The GeForce 9800 card still won't play. It's the same as before, on start up showing black screen with blue spots.

If I keep trying to start Windows in normal mode I rarely get to the desktop which then just freezes or goes Black then tries to restart as soon as I do something

I'm wondering if this 2nd hand card I've bought also has a fault and was considering buying a brand new card for around £40

Hi thanks for the quick response, I'm at my wits end with it and ready to throw it out of the window!

Yes I can confirm that the fan is ok. I ran it without the side cover on and the fan turns full speed at turn on and after a few seconds drops to approx 25%

Can you or anyone else recommend me a compatible card for hd 1080p video, I don't run games so don't need anything crazy,

the only card I can find is something like this,

Just a quick response to say I purchased a new ASUS Nvidia Gefore 640 2gb GPU this morning and fitted it up.

PC is now working like a dream with no faults, thanks for the help and I hope this thread is of use to others :D
