Haha! So much could have gone wrong! I knew there was a reason I hadn't tried anything like this before. OK, so the most logical way to tackle it would be to try it in a friends PC that has enough power then if it works, I'll need a new motherboard and if it doesn't, I send the card back to the retailer. Thanks for your help! I'll see how it goes!

Thanks for the fast reply KenB! I was hoping that wouldn't be the case. Someone has suggested to me that as my graphics card requires 500W that maybe my PSU can't supply it properly. Do you think I should try and get a better PSU or just cut my losses and return this card?

Hi everyone, I recently bought a new graphics card (Asus Radeon 7770 HD 1GB) and placed it in the PCIe slot. But when I start my computer it doesn't detect that it's there so I can't install drivers or use the card. Under Device Manager, the only display card that shows up is the on-board one. All I get when I plug in the monitor to the graphics card is a blank screen. When the PC boots I hear the card whir a few times then it settles down to a silent spin. I'm a bit of a PC noob and this is the first time I've tried to replace components myself. What can I do to sort it out? Background: The computer was a custom built PC made by a friend 5 or 6 years ago. He'd put an Inno3D GF 7600 GT in at the time, which had been working fine til a few weeks ago when I stopped getting a display from it. I took it to a computer shop who checked it and said my graphics card had gone but that the motherboard had an onboard card which I could use instead. That's what I've been doing but I missed gaming and decided to try and install a new graphics card myself. Computer specs: Motherboard: Gigabyte GA-M55plus-53g Processor: AMD Athlon 64 x2 4200+ PSU: Cooler Master Real Power 550w RAM: 4GB Operating System: Windows 7 64bit So far I've tried: 1 - Reseating the card 3 or 4 times. I'm pretty sure it's in right. 2 - Trying different 6 pin cables directly from the PSU 3 - Updating BIOS 4 - Setting BIOS to boot from PCI not on-board graphics 5 - Disabling on-board graphics in safe mode and then restarting. 6 - Making sure old drivers are removed (which they were, presumably by the computer shop that took out the old graphics card) I'm really stuck and don't know what to try next. I'm hoping that it's not going to be a case of the motherboard not working any more. Is there anything I've missed or is also worth trying? Thanks in advance!
