Sony Vaio not booting

My Sony Vaio suddenly shut down and when I turn it on, there's only a black screen with a blinking white underscore on the top left, the underscore after 10 seconds moves down a line, then after 10 seconds again moves down a line, then it just stays on the 3rd line. I've tried using my recovery disk and the Bootrec.exe > bcdedit /export C:\bcd_backup > C: > cd boot > attrib bcd -s -h -r > ren C:\boot\bcd bcd.old > bootrec /rebuildbcd > y. But all that doesn't work, I'm accessing internet through Splashtop right now, please help.
 
which model vaio? ...sounds very similar to a problem i was having awhile back. turned out that there was a problem with the battery. does it do the same thing if you leave the battery out and plug the computer into the wall? this will rule out the battery's involvement in the problem...
 
its VGN-NW26M, it still has the problem when i get the battery out, but it appears on the 3rd line and stays on the 3rd line, thanks for the help
