prakaa: yep it's spinning

Kezardin: Are there any codes displaying on the 2 digit LED display (next to the SATA ports) ?

broether-eros: I had a similar problem to this a while ago ... I don't think it's what's happening here but just in case maybe it will help.

For me the problem seemed to be between my MB and RAM, even though both worked perfectly on their own. The computer would boot up, but was hanging where it would normally enter BIOS, which is why the monitor was staying blank even though everything powered on ok.

Now I'm sure we've all experienced rediculous incompatabilities but moving my memory into the secondary set of dual channel slots did the trick, bios loads, and i could begin to install OS.

Also, as someone else has said that secondary MB power connector is essential, it could be 4 or 8 pin, some MB include a small plastic cover covering up the second 4 pin slot, but with any higher-end system you should use the max possible, so take off the plastic cover and make sure all inputs are attached to your PSU, afair that gives power to your cpu, while the 24 is for the MB proper. Check your psu manual because sometimes they reccommend using a separate (one of your auxilliary) connnectors with your 8 pin instead of the one that's sometimes attached to the 24 pin cable (at the base not the head). If that is not connected that will be your problem guaranteed. From what you describe if you think it may have overloaded you might have burnt out the cpu when powering up if the cooling gel wasn't applied when installing, which would really suck :( but that should have come standard pre-applied so hopefully that's not the problem :)

One other alternative, and I'm not sure if this is relevant, is that some MB use a switch for multiple graphics cards, that is, one of your pcie will run at 16x normally, but using the other(s) will run them all at 8x, meaning you have to use the specific 16x slot to get all channels for your single card. It's possible your graphics card was in an 8x slot instead of the 16x but I don't see how this could make it not run, maybe those 8x only work in sli/xfire and not on their own, i shouldn't think so, but it's the only thought I have left sorry :(

g/l with this, hope you get it up and running ok :)

prakaa: OMG THANKYOU! My friend tried moving the RAM to the secondary positions and it worked!!!!!!!!

broether-eros: That's really cool, glad it worked. hehe, i still have no idea why that was the problem with my rig lol, friggin weird hardware problems almost as bad as setting up networks lol :)

prakaa: Ok well it worked, but then, about 5-20 minutes in, about 21% through the Win7 install, the computer turned itself off. As well, we tried jump starting the mobo, and it still didn't work..
We tested the RAM, GPU and the HDD, they work for sure, we're only unsure about the PSU and the CPU (and mobo)

Virama: SWEEEEEEEEEEEEET.

Stoked for you my man. :D

prakaa: Damn another problem!
FIXED faulty stick or RAM :)

Zchinque: If you still have this problem, it might be that the CPU fan isn't properly connected.

prakaa: No it was faulty RAM. Thanks to Virama and you guys who've helped a lot
