I seriously need to upgrade my computer and I need some help. Awhile back, 4 yrs ago or so, my mom bought a Compaq Presario Desktop 7360 and over the years, I've been upgrading various components such as graphic card, memory, cd-drives. But I think I should upgrade the 433mhz cpu.I'm wondering, looking at the compaq presario desktop 7360 specs, what cpu can i upgrade to? Which ones would work? I really need help! Thanks.
