Parts that need to warm up. The BAD CAPS (see google) issue has this symptom as well as hard drives that need a little warm up time. Do your research and if no BAD CAPS get ready for a hard drive replacement.
Too bad you didn't post the make and model. My answer changes if this is a HP DV6000 or DV9000 series.

So when I first start up my computer for the day it will give me the Read Disk Error ( Alt Ctrl Delete) to restart. When I restart I will put in my Windows Recovery Disk and It will get stuck on the Vistas Loading Screen ( which is suppose to go into the tools and recovery part). So I take the disk out and restart my computer. It loads and boots like normal and my computer will run fine for the rest of the day even if I restart it will start normal. Any thoughts on what this may be?
