Poweredge 1900 issues

Try clearing the NVRAM using the jumpers on the motherboard (page 125):

If that doesn't work try reseating the processor.

Make sure to remove all unnecessary hardware - drives, controllers, expansion cards, mouse, keyboard.  Try it with only one DIMM installed, swap it to make sure memory is good.

Try the front VGA port too.

anyway i can check video issue, if its just the onboard video died im not too worried 

The only test for video (if you don't already have an OS installed), is to try a PCIe video card ... if it still doesn't work, it is something else.  The problem with this is that, in general, servers don't support add-in graphics cards, so finding one that works can be pretty hit/miss.

yep and yep, ok ill go argue with seller then, its weird that all the other error reporting works perfectly as if i disconnect any fan it shows the error as does putting the cpu into the cpu2 slot (leaving cpu1 empty) 

Did you boot/power up with the jumper installed, then power down, replace jumper, then attempt to power on normally?

If neither VGA port works, and you have tried reseating the processor, ensuring you separated the heatsink and processor to reinstall it, then I'd say your MB is dead ... I'd talk to the seller.

yea ill be if i can find a x8 pcie card 

"its weird that all the other error reporting works perfectly" (and the blue 'status' light)

That is usually indicative of bad video or the processor needing reseated, but if neither work ...

x1 will work in an x4/x8 slot and they are much easier to find.  Just be sure not to put it in the integrated storage slot, reserved for RAID controllers.
