Black Screen after RAM upgrade

To start off, I built this computer about 3 years ago. I recently (in May) upgraded my RAM to Corsair Vengeance LP, 1600mhz 1.5v 2x4gb modules. My memory in the Bios is underclocked, at 1514mhz and my processor is OC @ 3.6ghz. I started having a LOT of trouble with blue screens and crashes in the past month, so I decided to wipe the hard drive and re install Windows 7. Everything was going fine until I noticed that my RAM usage was really high (~35% when idle) and usually it is near 20%. I realized that one of my RAM sticks had died (thanks corsair) so my computer was only running at 4gb of memory, which explained the increased use.

Anyways last week I ordered 8gb more of the EXACT same memory module, so that I would have 12gb in total. I received them today and put them in, only to find that now my computer will not boot at all. My monitor (which works) shows no signs of a signal, even though all fans are running, and my motherboard lights are blinking accordingly. The computer will literally sit there and beep on occasion forever unless I turn it off. I cannot get access to the BIOS or anything else. I've tried clearing the CMOS via the reset button, and it did not work. I tried cleaning the connection ports on the hard drive, and I even re-sat the memory about 5 times to make sure it was seated properly.I also tried taking out the new modules and putting the old one back in(because one of them still works), and it still didn't work. So I am at a loss right now, because I'm not sure how to diagnose this. Does anyone know what else I should try?

My rig is:
Intel i7 920 @ 3.6ghz (air cooled, idle temp is 29 degrees)
EVGA X58 3X SLI motherboard (owner's manual says it can handle 12gb)
BFG GeForce GTX 295 graphics card
Corsair Vengeance LP 12gb (1600mhz, 1.5v, 4gb each)
Western Digital 1tb hard drive (I'm guessing it might be the problem)

Also as another note, I realize that maybe one of the RAM slots died. But, previous to the new Corsair memory, I was using triple channel Corsair 3x2gb. So I think the slots should be okay.

Do you have the latest BIOS? If not, get that, then install the sticks in the proper slots, enable XMP and select profile 1

Hey thank you for the really fast response. I'm burning the BIOS update to a CD now so I will try and see if that works. Also I tried again to revert back to just one stick of RAM and it booted correctly, so at least it works for the time being. I'll report back if yay or nay. Thanks again!

Alright, the BIOS update seemed to do the trick. Thank you very much!

Now to move onto my next two problems: W7 service pack 1, and my overclock is now the problem. So I suppose I should just leave it stock for now, fix one problem and enjoy it. Thanks again.

With the BIOS update, SP might load now, try that then let me know on the OC problems

The update still does the same thing. It will get to 30%, restart, then keep configuring until 99% and then it fails. I've run the system readiness tool, disabled my anti-virus, etc. but nothing really seems to work. As for the overclock, I don't know what is messing it up so badly. Everytime I go to my 3.3ghz profile, which is the one that I did not mess with CPU vcore (and also ran 2 stress tests for hours on end to make sure it was stable) I keep on getting the same result: Black screen, computer mothherboard won't do it's usual beep on start up, my fans are running fine, lights are on, but just no boot. I can't even get to the BIOS after trying to put enable one of my OC profiles. I always have to reset CMOS, and go back to default setting to start the computer.

It just occured to me, while I was writing this, that I believe it's still a RAM problem. I tried to set my RAM to run at 1333mhz earlier (it's at 1066 now) and the same black screen happened. The RAM is rated for 1600mhz, and I used to run it at 1514 with no problems. There must be some setting that I am overlooking.

Okay so my RAM @ 1600 suddenly started working haha. XMP Profile 1, set the timing to 9-9-9-24. My processor isn't overclocked at all yet, because I'm hesitant to try it now, but still this is a good start. I also tried SP1 again, no luck there. It's quite annoying not being able to turn off my computer without having to update it, then on startup, have it configure/ revert for 15min.
