Hi. Since my computer performance is not being so good lately, I figure I should update some of the old parts in it to newer and better ones. So in this thread I need people to tell me what I should upgrade (video driver, sound driver, RAM), what should I upgrade it with ( RAM company, prefer 1GB sticks), and the price. I think that my system specs I am going to post below should help you identify what kind of ram I can use. I like to play a lot of video games, so I don't know if 2 RAM sticks both 1GB from different companies, then one will have better performance than the other. SYSTEM SPECS: Manufacturer: MICRO-STAR INTERNATIONAL CO., LTD MOBO Model: KM4M-V Processor: AMD Athlon(tm) XP 1800+, MMX, 3DNow, ~1.5GHz Memory: 512MB RAM (can my computer us this RAM? http://www.newegg.com/Product/Product.aspx?Item=N82E16820144209) RAM Slots: 2 Hard Drive: 80 GB Video Card: RADEON 9200 SERIES Monitor: Proview Widescreen Sound Card: SB Audigy 2 ZS Audio [E000] (no sound right now don't know why https://www.techspot.com/vb/showthrea...640#post511640 ) Operating System: Windows XP Professional (5.1, Build 2600) Service Pack 2 (2600.xpsp_sp2_gdr.070227-2254) If you need any other info just tell me.
