Added 2 more gigs of ram. Computer won't boot

[Atwooooood]

So i just installed 2 more gigs of RAM in my PC, and turned it on, and it will either not do anything (the computer is on, but my monitor has no input, the light on the front just flashes), or if i turn it off and on a few times ill get a message saying "Overclock failed. Press F2 for SETUP or Load default settings"

I set my RAM speed back down to default, and tried booting with 3 sticks in, but it will only work with 2 sticks in. Anyone care to help me?

System Specs?
MB, Processor, etc
OS, /SP# etc
Memory Details...

It sounds like the memory is wrong for the MB...
Depending on the board, it may be necessary to load memory in pairs...
though this may no longer be true... or not true for your board.

MB: ASUS P5Q Pro
OS: Vista home premium SP1 32 bit
RAM: Corsair Dominator PC2-8500

I actually shut down and put a 3rd stick in to try again and it booted up, im bout to install the 4th DIMM and see if it works. Its the same RAM as the first 2 gigs i had in it so i know thats not the problem. Let me install this DIMM and report back.

So i installed that 4th DIMM, booted up, checked system properties, and Vista is reading all 4 gigs. Don't know why it wasn't working in the first place, but all that matters is that it is now.

Thank you Bookwyrm for your speedy response.

Sounds like the issue was "installing in pairs"?
OR
Perhaps they were not seated properly at first?

Glad you got it working...
