Update: Hiberation fixed my touchscreen problems which is good.
I have had the computer back in my car for about a month and 1/2 now, but a couple of days ago my inverter died, which is bad. Anyway, I had to take the comp out of my car. It's going to stay out too. My mom is about to buy a new car so, I am going to get her 95' Accord. So I'll be back, with a comp in a different car and this I am not going use an inverter. My inverter was the center of my problems, so I think it's definetly worth spending the next cash to buy a DC/DC PS. O well!
