[h3lp m3 please]

i have recently bought my new computer in parts and it finally arrived. i put it together and i get no signal to my monitor. i have

sapphire pure performance a9rs480 motherboard
AMD athlon x2 4600+ processor
thermaltake blue orb2 cpu cooling fan
Hiper type r 530watt PSU
250GB sata 2 hard drive
MSI 7900gt graphics card
2 x 1024MB ddr400 pc3200 ram
dvd rom + dvd rw
Aspire Xcruiser case

so far i tried both the blue orb cpu fan and the one that came with the processor with no luck.
ive tried the graphics card in another pc and it works fine
the PSU has 2 12V lines @ 17A and 18A if that helps
ive tried reseting the cmos and bios
tried running the motherboard outside the case
ive also tried running the comp on the bare bones ( Mobo cpu fan ram)

finally i think the culprit could be the ram as the mother board is dual channel and thta the ram may be single channel but not sure

i am very unhappy

Unfortunately Sapphire does not give you much information on their website. It should not matter if the memory is single channel or dual channel it should still run, just at a lower speed. I notice they have the ATI crosfire 200 on-board graphics. Have you disabled the graphics, or switch it from on-board to PCI-E, in the BIOS to run the graphics card? Have you tried pulling out the graphics card and seeing if the on-board graphics work? I don't think the problems is with the other hardware. Another thing is the graphics card needs to be plugged into the power supply. There is a 6 pin connector at the back of the card that needs to be hooked to the PS's 12 volt line. You should have got an adapter with the card to use if the PS has no 6 pin connector.
