Sounds like you might have a few problems.

First off, since you are not getting all of the power options as usual it sounds like you may be missing some drivers. This could also be causing the Blue screens. After you installed XP did you make sure you you reinstalled all of the drivers for you hardware. Sometimes XP will find some for you but you may be missing drivers for devices such as audio and video cards, networking cards, and for you chipset. You should verify that all of the drivers for you hardware are installed.
First right click on My Computer and choose Properties. Once the dialog box appears click Hardware. Next Click Device Manager.
When Device Manager loads there should be an expanded area that has yellow question mark icons. Any of these are hardware devices that are missing the software required to make them run correctly. If you have some of these the easiest option is to go to your computer manufactures website and find a link for support and drivers. This will work if you have a PC from a large vendor such as Dell, HP, etc. Another option is to find a drivers CD/DVD that may have come with your computer. If you have a custom built computer you will most likely have to find the drivers yourself which will include determining what devices you have (usually can be done by looking in the computer) and searching online.

After you have all of the drivers installed on your computer some (if not all) problems should be fixed. If you are still getting blue screens or are having issues with the power options of your computer you could have a much larger problems. This could indicate that a device inside of your computer is working incorrectly and causing problems. Some things to consider are the age of the computer. The older it is, the more likely the hard drive is to fail (which could cause this.) Also, did you make any changes to your computer before the BSOD appeared. If so, this is most likely your culprit and can be fixed by removing that piece of hardware from the system.
Some things you can try are running a Chkdsk in the command prompt. This will you give you some information about the state of the hard drive but is greatly limited. Click start and then run. Type CMD in the run box and press enter. When the screen comes up type chkdsk and press enter. When the process is complete notice the amount of bad sectors. If you have any, this is a bad sign and your hard drive may need to be replaced.

A final test would be to check and see what tests your bios might have built into it. Some have advanced hard drive and other hardware diagnostics that can tell you if you have serious problems. The bios is the screen that appears with your PC manufactures logo during boot up. You can usually log into it by pressing one of the F* (F2, F10, F12, or DEL) keys when it appears. Each bios is different so you should check your manual.

If you have to replace anything on the computer or if all else fails, consider that age of the computer. If its over five years old consider getting a new one because computers become outdated extremely fast and the cost of replacing anything on this computer could easily go towards purchasing a new one.

Hope this helps!
