New build --- monitor will not come on!

[Knyteguy]

Hi all, having some serious stress issues trying to figure this out!

Ok, so specs first I guess:

i7-920
Asrock x58 extreme mobo
HIS 5870 Radeon
Corsair 750w psu
G.Skill 3x2 gb DDR3 ram 1600 1.5v-1.6v

Ok, now I've tried just about everything I can think of, and lastly it's looking like RMA, but I really hope it's just some minor oversight causing all this mess.

I've plugged in 12v & 24pin connector to mobo
I've cleared the CMOS
I've tried 2 different video cards, both DVI slots on em, I tried HDMI on the card that allowed it. W/ 2 different monitors as well.
I have the mobo mounting pins in
I can't see any place the mobo could have a grounding problem (i.e.: touching the case).

Any ideas? I've been racking my brain with this for hours. Everything turns on, fans run, front panel works, HD light comes on, everything but the monitor. I can't check for beeps, no internal speaker. I've mounted the RAM in a few different ways, using all 3 sticks alone.

I just took off the battery, letting it sit out for now.

Please help!

try using a different pci-e slot for your video card and see if that works. if so then you have a bad slot. don't think this is an issue for your mobo (using 2 or 3 pci-e slot) but check your manual to be sure. hope this helps.

Try the monitor on a differnt system and make sure it works. You can also connect a speaker to the motherboard to listen for a beep code that may indicate why the system isn't posting.

Plugged power into the vid cards?

like intexity said, try using a differnt pci-e slot. Some motherboards have a primary PCI-E 16x slot that need to be used first. for example, the Biostar TA790GX A2+ that i have, requires the videocard to be in the bottom PCI-E 16 slot. then i had to a paddle card into the top PCI-E x16 slot so that the videocard would operate in 16x mode.

Could always pull the card and try the onboard video if you want to know whether or not it's the monitor.
