Hard drive/ RAM. - meow

Weeeelll um. Most of you.. if you are in my buddylist or guild would know that : I lag a LOT on MY computer ( not my mom's! ). Well this computer does. Really, really, really... suck. ._.
I might switch to a different old computer or get a new hard drive... but I'm very stupid

So what does my computer need? It literally sucks, sucks, sucks. I can't do crap without it freezing or lagging for minutes. I've been thinking of uninstalling banned story and stuff first because.. I really CAN'T use it on the computer and it does take a bit of space. *Frowns*.

If you have seen me in CPQ or anything. Around the FM you will notice I stop for a few seconds to even about five minutes. I lag like heck in PQs. Yesterday I was PQing w/ Candice, Zeehan, Hai, Kevin, and some dude. It was at seven minutes left and I lagged really bad.. The screen froze and I waited.. the lag stopped five minutes laterrr... then I lagged again. It stopped at 30 seconds left. Then I had few more lag spikes and when the WIN sign came down I lagged again. It took about two minutes more for my screen to get to Spi...... w/e his name is D:< and.. and. Yeah. The next PQ I lagged for three minutes and disconnected.

So I am not sure about exactly what I need. Is it a hard drive or ram?
I'm gonna switch to the other computer TODAY and see what happens. It's in Chinese so Jamie's gonna be a dumb dumb.!
