Ok, here's the situation. Been having a weird computer problem for a while. Computer will freeze on bootup after being off overnight. Once it's warmed up, no problems. I did tons of research and figured, ok, it's a power supply problem. I finally bought a shiny new OCZ StealthXStream 400W PSU and threw it in. The power supply works great!. Unfortunately, it didn't fix the problem.

So now I'm thinking maybe I need a new motherboard and processor. I have an HP m1195c Media Center pc. It has an Asus Puffer motherboard with a Pentium 4 3.0 ghz processor. What I'd like to do is upgrade the motherboard and processor and be able to keep the HP case. It would also be nice if I could still use my DDR PC3200 memory.

Must also have support for PCI-E graphics for later upgrade.

Any suggestions from those more knowledgeable about computers? I've done some research, but got a little overwhelmed. When I built my first computer way back in 2000, all I had to worry about was socket A or 775, pentium, celeron, athlon, etc. I haven't kept up, now I don't know what's what with core i7, duo, quad, ad infinitum.
