My computer came with 256 MB of pc 133, and I then put another 256 MB of pc 133 ram in it. When I unplug my computer and turn it on, it reads like 480 MB of RAM, but if I unplug it again, and then turn it on, it will read 512 MB. This happends everytime I unplug my system. Once it reads 512, it is fine until the system is unplugged again.

You don't mention the particulars of the computer or when you got it. But my guess is that the RAM sticks are incompatible with each other. Try one of the RAM sticks by itself and see if the computer reads it correctly. Then try the other one by itself and see if it's read correctly. If each one alone appears to be ok, then the two together have a compatibility problem. Even though they are both pc133, you'd be better off using RAM sticks that are absolutely identical.

It is possible, however, that the motherboard is the problem, but the compatibility issue is where I'd look first.

Good luck,

Does your mainboard have onboard video?

If it does, and you're not using it, it may be trying to allocate 32mb for video memory for some wierd reason. Im not sure exactly how you'd fix it, but it's the only reason I can think of...

except of course faulty/incompatible ram like was previously mentioned, but if you can fix it in the same manner every time, and the system is stable, Id doubt its faulty.

I do not have onboard video. The system reads the correct amount of memory, and the system is very stable. The only time the system does not read the correct amount of memory is when the computer looses power. When this happends, I just unplug itand re-plug it in and it is fine.
