I tried upgrading my RAM from 64mb to 256mb today. After installing the two sticks of 128mb RAM, my pc started up, but, nothing else powered up. The monitor didnt turn on either. After troubleshooting and realizing they were installed correctly, I called Gatway and asked what else I could do... He told me that my power supply is probably to small. Only 90watts. He told me he doesnt use anything less that 300watt. Just before I go spend the money on a new power supply, I would like some more opinions. Is it possible I have to much memory for my current power supply?

Are you using a desktop or laptop? I've never seen a desktop with such a skimpy power supply...I thought mine was bad and it is 135 watts. But even from that I run two hard drives, a DVD, CD-burner and three network cards.
Even if you did have a 90 watt power supply, installing more RAM will not overload it, memory uses infinitley smaller amounts of power than hard drives or even fans in the computer.
Sounds to me like you installed the memory modules the wrong way or they are incompatible with your computer (ie PC100 instead of PC133 memory). If you have a wrong memory configuraton, that would explain the lack of video.
If you could give me more details about the system I might be able to help a bit more.

I have a Gateway 350 mhz pc. I am supposed to use PC100's. I have PC100's. I have a desktop pc, and it does have 90watt power supply. The Gateway guy told me that he suggests 300watts. He also said that is the probable cause of the ram not working. Is it possible I must change the bios or anything so it will read the memory?

Ok.. Another thing thats happening.. When I run the 64mb ram it works, when I add 128 with that, my pc turns on, no beeps, and doesnt turn on my monitor. I take the 128 out and with the 64 it works again... Could it be a power issue as said? I know 90 watts is really low.

Well I figured it out. The generic ram I was using wasnt compatible. So I am now using some non generic stuff and my pc is flying, all on 90watt. I cannot upgrade the wattage because my case is to small.

Glad to here you got it working. I agree that 90W is too little for most of the devices we have on our machines these days, but wouldn't think that adding another stick of RAM would put you over the edge.
I've had the occasion to install more RAM on my machines and have had ordered it over the net from http://www.crucial.com. If you have a brand name machine it's just a matter of picking the make and model.
