systems a non starter

So i just built this system with parts from the members market and whilst it starts, it just beeps and nothing appears on screen.

The motherboard is a Sapphire Crossfire Xpress 3200 PC-A9RD580adv here

Now this motherboard has an 8pin power connection which i havnt seen before (usually 4 pin) and the power supply being used doesnt have the 8pin connector. Putting 2 and 2 together im guessing this is the reason that theres a red led on the motherboard with "5VSB-led" lit up?

GPU is an x800gto and cpu is an opty 150

Any ideas ?

Also is it correct that the gpu is in the master pci-e slot as i've never used a crossfire board or wont it matter

bump.

i'm gonna try a different psu but i cant see that being the problem as this one powers on fine. also gonna try the otehr pci-e slot for the gpu.

Can i use the 4 pin power connector in the 8 pin power connector slot ? ? ?? ?

You should be able to use the 4 pin square-ish connector in the 8 pin connector on the mobo, tis what I do for my ds3p with an old Enermax PSU. I think the 4 pin should only go in 1 way but it's be worth just double checking in the mobo manual on how to connect it.

hey mate, is your monitor pugged into the right connection on the GFX card?...dunno about yours, but when i first put my shiny new x1900xt in i thought it was borked, PC booted fine, but no picture, i switched the conector to the other connection and it works fine, if its not that then im stumped :/

well, my GFX card has 2 input slots (+ a TV one, but that doesnt matter)

back looks like this; | [+:::::::] ( O ) [+::::::::] |

two DVI slots, try both

looking at it from the back i have to plug my TFT into the left socket.

tried a different psu and still no joy, the 5vsb light on the motherboard stays red when powered on and still no output from the vga :confused:

ok i'm still stumped on this.

Would it be wise to buy a atx2.x psu that has all the correct connectors and not try to use the 4 pin plug as im getting no where with this and cant think why
