I've tagged this under hardware as I think its a hardware issue... So, I've rebuilt da PC in its new case, and I double and tripe check all of the power connectors, depress the button.... and... fans whirr... hdd whirrs.... pump starts... and not much else... Nothing on the screen, even though all of the debug LED's on the board seem clear... The one by the bottom of the board is yellow, and the one by the ram is green, but Im not sure what colour its supposed to be I also have 2x Red LED's lighting up on my GPU (X1800 XT) and thats it. I've tried different PCI-E cables in my HX520 and no luck... Help please.!
Dead video card? Only thing I can do is suggest to cut the rig down to the bare minimum and get testing. Got a spare GPU?
The red LED's on the cards usually indicate lack of power. A) card issue. B) PSU issue, maybe you blew the rail that powers GFX
My Asus Board has LED's by each of the Card slots, that light up red when the card isn't in properly, or not making good enough contact. Have you tried reseating the Graphics card?
Yup... even though having a bad GPU would normally be cause for beep codes on most system, provided your system speaker is connected. could also be a dead CPU, RAM even though in the case of the CPU it should spin up, spin down, and that's that... in the case of RAM, beep codes again...
