okay this will be a bit long winded as a lot has gone on but i am completely baffled and thought i should ask for some help, im generally quite technical and this is the first time iv asked for help so here goes

okay so a few days ago i decided to move my computer to a new case an xblade case to be specific. i literally swapped everything to the new case and re installed windows 7 for a fresh start, everything was working fine using a Radeon hd 5450.

then i got back an older computer i had lent to a friend which i intended to use in another room, it to worked okay except i had not installed any OS and it was only running on the motherboard graphics. so i decided to take the graphics card out of my main PC the Radeon hd 5450 and put it into this system and put a new graphics card into my main PC, when i done this however i received no signal on the old computer at all and after changing everything i could in the bios i gave in and put it down to been a dodgy PCI express.

this is where it gets irritating, i put the very same graphics card back into the original PC it was in and the same happened as when i put it into the old computer the monitor states its receiving no signal. this started to worry me and i now had reason to believe it must be the graphics card that's broken, so i bought another graphics card a Nvidia 9600GT and put this into the main PC the one that originally had the radeon hd 5450 and worked fine. but this did not work either and it was still displaying no signal, i put the 9600gt into the old computer that didn't work either so i eventually come to the conclusion BOTH motherboards must be broken. i got another one swapped all the parts again tried both the cards and STILL the same problem, i swapped PSUs memory everything i could and nothing has worked it almost feels iv been cursed not to be able to use a dedicated pci graphics card on these computer i need help is there some where iv gone wrong

thanks in advance for any help you can give and sorry this has been such a long post

quick question. if you pull out the gpu, and plug a monitor into the io port for the onboard video do you get anything (on your newish computer, not the old one)?

sounds like your old computer burnt out the gpu (probably a dead/dying psu)... and your new gpu was probably broken from the get-go.

The chances the newish pc's mb is shot is pretty thin... but... here is something to try.

pull the power plug on the newish computer. pull the battery out of the mb. use the jumper to CLRCMOS. Wait a minute or two. plug the battery back in. put the jumper back. plug the psu back in. turn pc on, go to the bios, make sure the graphics setting is set to native pci-e as primary graphics provider. save and turn off system. plug in new gpu, connect the monitor to it, turn on pc and see if you get video

we're just gonna make sure the gpu is broke.

nope there is still no signal and iv done this on 2 of the 3 motherboards now just to be sure. i also thought it may be short circuiting from the video cards back panel touching the metal around the case so i took it out of the case all together and tried it without it been inside the case still nothing from the video card

yeah iv been grasping at ALL the straws for the past couple of days and the gpus are both clean i can send u pictures if you like the only defect on the nvidia is 9600 GT is it is missing one fin from the fan but i dont think that will make much difference and the radeon has no fan its low profile

i'd say you got a bum 9600... sounds like you plucked it off ebay. i'd start the process for a return/refund. ebay is REALLY protective of buyers. you won't have to prove squat, just the fact it doesn't work is enough.

shame your other gpu was blown up.
