troubleshooting a new graphics card

Haydenh · Apr 21, 2014

i recently bought a new graphics card to replace my old one, the new card is a nvidia geforce GTX 650ti and the old card is a nvidia geforce 9600 gt the card is brand new and has never been used. i read a few sites on how to install a new graphics card to make sure i installed it correctly and they all said that some cards require you to uninstall the old drivers and disable the old graphics card which i done, i also installed the drivers for the new graphics card using a disk. After turning off my computer and unplugging it i removed my GPU from the motherboard and replaced it with my new one. i plugged in the 4 pin plug, made sure it was seated correctly and then plugged in my computer and turned it on, i also used the same cable which is a VGA cable with a DVI converter on one end (only plug that the old GPU had), i am using my tv as a monitor at the moment so it was still plugged into there. the computer started up and the fans on the new GPU were running fine but there was no output to the tv, it just displayed no signal. so i tried different cables such as a HDMI and a plain VGA but none of then seemed to work. i removed the new GPU and put the old one back in and it worked as normal, so i tried once again to use the new GPU but it still didnt work, im pretty sure my power supply is sufficient and i have checked the socket that it fits in and all the connections, as i said the old one still works fine i even tried my monitor that i used to use and there was still no signal, i cant think of anything else that could be a problem. also the computer was a custom build and was not a off the shelf PC it is also pretty old (6 years) any advice?
thanks hayden

When you plug in the new graphics card, is there an input through the onboard graphics?

Haydenh · Apr 23, 2014

i don't think there are any onboard graphics, there is no plug socket on the back of the pc for any video cable (VGA, HDMI etc.)

Did you uninstall the GPU drivers from the old card before making the switch

Haydenh · Apr 23, 2014

yes i tried doing this, and when this didnt work i put in my old graphics card and it reinstalled the old drivers so i have tried it both ways

Haydenh · Apr 23, 2014

also when i put in my old graphics card after trying the new one it went to the windows recovery screen, and it seems like it doesnt start up windows with the new card

Deemo13 · Apr 24, 2014

But it does start with the old card. Strange, but this happens to people sometimes. Would you happen to have another computer you could try with the card?

Deemo13 :

Yes it starts with the old card but unfortunately i don't have another PC that I could use to test it

Haydenh · Apr 24, 2014

any other suggestions?

Tradesman1 · Apr 24, 2014

Did you plug in the power cable to the GPU, you mentioned plugging in a 4 Pin, the 650TI takes a 6 Pin PCI-E plug

Deemo13 · Apr 24, 2014

Your motherboard is a P5Q, which should be a SLI motherboard. Have you tried the new card in the other slot?

Tradesman1 :

sorry i meant i plugged in the 6-pin power cable, so yes i did plug it in

Haydenh · Apr 24, 2014

Deemo13 :

my motherboard only has one PCI-e slot for a graphics card

Deemo13 · Apr 24, 2014

Ah you're right, the Deluxe model had 2. My mistake.

Haydenh · Apr 24, 2014

ive read other answers that have said that you need to disable the integrated graphics to get the card to work, but one my Motherboard doesn't seem to have any and two when i change from the new card to the old one it works straight away without changing anything so i still have no idea. a power cable came with the card which has two female sockets on the opposite end of the 6-pin plug but using this done nothing either, i also tried unplugging the disk drive which also make no difference.
thanks

Maybe try using the 6-pin off the power supply instead of using the one that came in the box.

Haydenh · Apr 24, 2014

i tried this to begin with, im very confused as to what the problem could be

the graphic card you bought is a cheap chines fake card which claims 384bit and ddr3 ram but its very very slow and bad quality graphic card than original gtx650. one more thing it doesn't support HDCP as well. try any other good original graphic card of gt series they are better than this chines gtx650.

Yeah I sent it back and was refunded, I brought an AMD MSI radeon R9 270 so it's alright now
