If LCD screen, remove ac power plug to monitor for a few seconds and return ac power and see if it syncs up.

If not then suspect some issue with video adapter to screen or all or part. Might be the system is not booting up at all.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, Make an autorun.inf folder on all usb drives.

"OUT OF RANGE H:30-70KHz" is not referring to the power adapter frequencies but the SYNC signal being sent by your Video Card.

If you get this during Power On Self Test, POST then your video card has come lose from the Mother Board or gone bad. Pull the video card and try reinserting it. It may be time for a new video card.

If you get this after the Windows logo then simply boot into safemode (hold F8 on bootup) and set your refresh rate on the display settings to something like 70KHz.

Its not an TFT and the message on the screen i.e. "OUT OF RANGE H:30-70KHz
V: 50-160 Hz. PC DISPLAY SETTINGS CORRECT?" appears and the system doesnt boot up at all. Another thing I realised is that as soon as you connect power, it switches on yet I usually did it manually
