Thanks for the help so far. I'll defenitely consider a new PSU if I change the motherboard, since it would be for a newer processor. As for RAM I have a 256 of PC2100, and a 512 stick that's PC3200. For some reason, according to AIDA32, the 512 stick is only running at 200 mhz. I have a recovery partition on my hard drive that is specifically made for re-installing windows and reformatting c:. The downer is that it does include all the HP drivers, but it wouldn't require reactivation and would be easy to do. my video card is PCI, since my motherboard doesn't have AGP or PCI-express (I didn't know much about video cards when I bought the computer almost 2 years ago). So, considering all that I'd have to replace- the PSU, maybe I'd have to buy windows, the mobo and CPU purchase, and a new video card - maybe I should figure out all what the Trigem Glendale can recognize for processor speed and L2 cache, or maybe it would just be better to buy a new computer and sell this one. What do you guys think?
