Hey all, I've lucked out yesterday as my old Dell computer wasn't functioning properly and they sent me a replacement computer. What is lucky about this, is that my old computer was a P3 500MHz and this new one is a P4 1.6GHz. Anyways, I have a few questions. First, there is a lot of hard drive activity going on, even while just sitting here typing this, or reading a webpage. I don't see what is going on that the OS would need to access the hard drive constantly. Well, it seems to happen more while I'm typing then just letting it sit though. Just so you know, this computer is running off of Windows XP. Second, why does this computer use PC133-SDRAM? I thought P4's only used RDRAM? And some other boards with chips from VIA and the like were capable of using DDR-SDRAM. I'm sure that not using RD or DDR is certainly hindering the performance of the computer. To add to this, there aren't any Rambus Ram slots on the motherboard either, so I'm stuck using PC133. All in all though, I can't complain in the slightest, as this computer was totally free..along with the matching black monitor, speakers, keyboard, and mouse. I'm using my optical mouse instead though. Thanks. P.s Do you think I would be better off killing this install of WinXP and putting Win2K on the machine?
