XP reboot - Safe Mode

1. It will reboot into safe mode. Any ideas of the problem? Does this sound like a hard drive problem?

If it boots in "Safe Mode" (of which there are several types), not likely IMO. Review the content of this article for what it does.

2. It tries to reboot but goes to a blank screen.

Please explain the process that system goes through and anything else concerning the set networking process, how, and their connections which you think are important. for example:

a. In order for us to analyze a potential problem and offer tips, we must rely only on the question content to attempt a qualifying response. A question should state the exact system error(s) - spelled, spaced, and capitalized just as it is shown on the display. Helpful perhaps is the window title in the colored bar of the report and any information when provided by a "Details" section also.

b. Most error messages:

? usually list and describe standard default error messages - written within the program code and usually recognized by most "Gurus"

? the troubleshooting techniques may be published and explained in the Microsoft Knowledge Base (MSKB) library for the Windows operating systems or elsewhere on the WEB and may be searched for with accurately reported information.

c. Correct and complete information is vital if informative help and answers are what you seek. You want that Guru who reads your plea to understand the question, to possibly know the answer, and to reply giving you their assistance.
