I had 192 mb of ram, and I recently bought 512 mb more. My motherboard supports seven hundred and some mb. I had win98SE, and it recognized just 400 and something mbs, as I was expecting, but then I upgraded XP nd I thought it would recognize the whole 704 Mb I had, but it hasn't...What can I do?
Another question - during XP instalation, I had the option to erase or create partitions to install xp; I have one 13 gb hdd, with a small 3 gb partition and a primary 10 gb one.
During xp instalation, I supposedly deleted that partition and installed xp on the primary partition with 10 gb, thinking that as I removed the small partition, I would have my whole harddrive with 13. But now I have only one partition with 10 gb, and supposedly a despartitioned 3gb space in the disk that I can't use, as there is no letter assigned to that drive. What can I do?
Thanks, in advance,
