Why wont my laptop bootup?

I hold a Sony Vaio PCG-GRX560 laptop. I hit the power bower, and the laptopl will turn on. The power button LED says it is on. And it make those little deep sounding clicking noise (best i can describe them) that some computers make when they are booting up. However, after this crash, it doesnt do anything. The problem is not consistant, but it has done this several times. It happen weither its running off the power cord or the mobile. The laptopl has be in service until that time, and it is out of warrenty now. It is aroudn 4 years outmoded. Any ideas why this could be occurring? Could a run-down (permanately dead) battery be the grounds? Please, leave any accepted wisdom you have as to what may motive this and what will solve it. Thank you very much.

Answer:
I'm guessing you're not getting any manner of picture on the LCD from your description. If that is the bag, your LCD or part of the graphics display may be worn out. Try plugging an external monitor into the laptop (you should be able to find a blue VGA connector on the side somewhere) and see if you obtain a picture. This will determine whether or not it's just a graphics issue.

If you are getting a picture, you may own something in the startup routine that desires to be fixed. Test this by powering up the PC and tapping F5 or F8 to capture to the boot menu. A black screen near white writing should show up... select the first Safe Mode and try to boot into Windows that way. If it go there, you probably enjoy something in startup or elsewhere that requests to be fixed. Click START, then RUN, type "MSCONFIG", select the STARTUP tab, and next click DISABLE ALL. Click OK and let your computer reboot into usual mode. If it gets here, you can go spinal column to MSCONFIG and start re-enabling the lines by clicking in the boxes to the gone and rebooting. Once it stops booting into normal mode, you've found the problem.

Hope that help!
