I work in Wakefield hehe.
I read all way back and went through your PC spec. Noticed you have Hyundai B90A monitor that only use D-Sub, think you used DVI to VGA adapter to display information so maybe it possible motherboard beep after PC on could mean that it warned you there is a faulty DVI port.
Do you have HDMI to VGA adapter to test see if information will display fine?
No reply from Overclockers Customer Support.
I'm starting to suspect that I have just thrown £120 down the toilet.
You were advised to get a new Psu but chose not to.
Trebz do you have a HDTV in your house?
If so try using that to see if you can get the card to display, using HDMI cable.
Unfortunately these sort of upgrades in older systems often high other weakspots that will need upgrading.
Edit- as Idleman mentions though, no way would i be using molex cables to power it, you really need a better PSU bud.
What does that mean?
So you are saying that to make this work I need to buy a power supply. I already have a 700wt power supply which should more than cover it.
Trebz you have an Old ass PSU bud that isn't designed to power a gpu like the 7950, if it was, it would have the required connectors, it doesn't, there for it isn't.
Try a HDTV, but unless the fans are spinning on the card, i'd not bother until you're able to power it correctly.
Wow you have HDTV? Make me wonder why you used old VGA monitor with a maximum 1280x1024 resolution. You would had rid of it long time ago and stick with HDTV which gave much better maximum 1920x1080 resolution with HDMI cable.
If it worked with spare HDTV then your VGA monitor is blamed for issue or if it still not display information on screen then it your motherboard issue because GA-MA770T-UD3P is 6 years old now with no further new BIOS updates.

Just about every new graphics card bundled 1 or 2 PCI-E molex cables, it worked fine as long PSUs don't have PCI-E cables. Last time I used PCI-E molex cable when I had Geforce 8800 GTX because it got 2 x 6 pin PCI-E power connector and my old PSU had only 1 PCI-E cable.
