Problem with new memory?

I've just installed 2 extra RAM modules into my PC and when I first booted up I got as far as the post screen where it checks the processor and then it stalled.

After testing all the RAM modules (the last lot I was sent had a faulty one) they are all fine, so I went ahead and put them all back in.

Now I got nothing, no post screen and no error beeps.

Im using a 550W PSU and have an 8800 GTS, could a lack of power be the problem or could it be something else?

Update:

Would just like to add, not had a single problem with this PC and it's working fine with the 2GB of RAM already in here.

Update 2:

The RAM modules I am using are exactly the same, ie make and model.

Update 3:

Im using a ASUS P5N SLi and 4x1GB ram modules.

Update 4:

Oh and I dont get the BIOS screen, my monitor stays on standby when I switch the PC on.

    ok..if you put in your ram modules and boot the system and the system goes beep..beep..beep then you have not fixed your ram modules in the proper way or there is a mismatch in the type of RAMs being used i.e. you trying to use a DDDR2 ram in a DDR slot.! check the previous rams for a comparison...and i hate to say it if no post screen means either you have fried one of your slots or one of your ram cards..just check them up again. Check all the rams 1 by 1 if the boot the system up individually..if that too doesnt work might be an issue with your board..my reccomendation just show it to a qualified service person.!

    No error beeps? No post screen? Do you have the BIOS screen or does the PC go blank before you can do anything? If you find that it sometimes boots and then shuts down or doesn't boot up at all then your motherboard is fried. If that's not the case then I don't know what to suggest as it could then be a serious issue with your new RAM. It could be dead or damaged. Sorry I can't help any more but looking at the specs of your equipment the last suggestion could very well be your power supply as you have quite high spec equipment.

    Oh, one last thing...have you overclocked anything in your pc such as the graphs card. That can prove fatal if you don't know what you're doing.

    OK. It sounds like that you MAY have a potential problem with your motherboard but I couldn't say for sure. Did you have many problems before the difficulty began or did the screen just go straight to stand-by?

    I ask this because I had the same problem. I couldn't even get the pc to run and the screen stayed on stand-by.

    What is the power of your PSU?

    I have a 500w psu because it wasn't enough for my 250w to run my 8500gt graphs card. Judging by your motherboard I'm guessing that you must be running something at least in the region of 300w but couple that with a powerful graphs card and it soon becomes inadequate.

    Hope this helps.

    Perhaps you have installed too much RAM.

    Check your mainboard specifications to see the maximum amount of RAM it will support.

    Usually, the maximum amount of RAM divided by the number of memory slots on a mainboard gives you the maximum supported RAM for each slot.

    For example; if the mainboard specs say that it will support a maximum of 4GB of RAM, and there are four memory slots, then each slot can only support a maximum of 1GB of RAM each.

    Hope that helps.

    Remove the extra RAM and go to crucial.com. scan your system in the memory section. It may be that your PC can't handle the amount of RAM installed. Crucial will give you details on that after the scan
