Please give us some history on the problem, and post as many details as you can about what exactly you mean when you say it won't boot (does the fan turn on? LEDs? Can you hear the drive spin? etc., etc.)
I did a fresh install of everything (XP Pro, Office 2003, etc) about two weeks ago. Everything worked great for 3 or 4 days, and then last Friday morning when i turned on power, the computer hung up on the SONY logo with all LED's going. Tried rebooting same result. Tried booting up in Safe Mode, same result. Sequence is XP Pro logo on black screen, very brief bright blue DOS pop-up page (so fast i cannot read the page) and then hangs up again on the Sony Logo
We ask that members not tag their questions on to a thread previously started by another member (regardless of how similar your problem might seem). Not only does it divert the focus of the thread away from the original poster's problem, but it also makes it less likely that you yourself will get the individual attention that you need.
Please start your own thread and post your question there. When you do, please try to give us as much specific info as possible regarding the problem (exact error messages, system specs, etc.).
