Hi

I have an older computer and installed new memory and when I start the computer it does not boot. Theres just a blank screen.

I used the System Information for Windows program and it states that the motherboard supports a maximum memory module size of 1 Gb. The new memory stick Im using is 512 Mb. The memory sockets are 168-pin SDRAM DIMM.

Nope. Its just a blank screen. Eh, how long should I wait for any error beeps more than 5 minutes?

No. If your don't hear any beeps within 10 seconds, you probably won't hear any at all.

A couple of things i would like to know:
Do you still have the old RAM?
Is this just one new stick of RAM or more?
How many RAM slots does your Mother Board have?

Yes, I still have the old RAM and that still works.
I bought two new sticks of the same type. Ive tried them both together and alone and have the same result.
It has 3 slots. All of which do not work with the new RAM.

Yes it is a DFI WB72-SC/SR.

I would almost bet you are trying to run high density RAM in that board. Let me do some research.

I am a retired Ford tech. Next to Fords, any computer is a piece of cake. (The cake, its not a lie)

3770K @4.5, Corsair H100, GTX780, 16gig Samsung, Obsidian 700 (yes there is a 700)

I checked a couple of other sites and I read that registered memory is not compatible with older motherboards like the one Im using, and the new RAM I believe is registered since it had 'REG' listed so Im guessing this might be the problem.
