so i bought a 512mb ram stick (the max my computer can hold) but when i tried to put it in, and boot up my computer, the diagnostic said that there was only 32mb of ram in one slot, as opposed to 512 in each of 2. windows wouldnt load with that, so i took the new stick out and it booted as usual. is it a defective stick? it says 512 on it, and the other stats match up to my requirments as well.
If you're using more than one stick, try each stick individually. Maybe one of them interacts badly. If you only have one stick or that doesn't work, call the RAM manufacturer. They'll have more experience with this than your motherboard manufacturer.
When booting, hold down DEL (usually) to enter BIOS setup. Search the options for something that could be causing this. Look for words like "memory" and "large".
You might try updating your BIOS. If you have an old motherboard, that's terribly difficult and dangerous. Download the BIOS firmware from your motherboard manufacturer's site, not the BIOS manufacturer. Follow their instructions.
