AMD info? It's an Intel system... with an nVidia video card.
If the system is not working from a cold state, it's possible that you have some components on the system that have become heat sensitive. There's usually two ways around this:
Don't shut the system down when you're done using it
Start considering upgrading
I only say that last one with a bit of reservation because it's possible that my diagnosis is completely wrong - but in my experience the older a PC gets, and when it starts exhibiting this behavior, it's time to start thinking about getting it replaced.
You could give the components a good once over - my favorite software is to use Hirens Boot CD, then run a MemTest on the RAM, and just about any assortment of the hard drive testing tools (I use GWSCAN) to verify system integrity.
If the components are sound, and those tests say they are, then I'd start wondering if the components are just on their way out.
