Hi guys, I have here with me a HP Pavilion DV 4000. It's a pretty old laptop but used to be considered a beast during its time. In a brief run down, here are the overall specs. Windows XP Home Edition Intel Pentium M 1.86 Ghz ATI Mobility Radeon X700.\ 1 GB RAM. Now, my question is, I've been thinking if it is worth spending money on a brand new laptop, or if I should just up the RAM on the current system to say 3 GB or 4 GB (via pae) or a dual channel 2 GB? For some reason, this system seems to 'freeze' out of the blue for no apparent reason. When this happens, the CPU usage shoots up to 100% for a couple of seconds before dropping back down to 0. I initially thought a clean reinstall would fix this, but unfortunately, it did not. Is it time to move on to the world of Core 2 Duo? Or will having more RAM fix this issue? My GF doesn't need to do much on the laptop, but she does love to have like 10 ~ 30 tabs opened in Firefox. I'd appreciate any advice/input on the matter. Cheers.
