Suddenly, I can see only a part of the display width. I can't control the width size in the screen setup (all the other functions are OK)

see that it may be from the resolutions..if you give it a smaller one ..and it is a wide screen format will hae black 2 inches wide band on each side... just right click on desktop properties and settings ..and restore a normal resolution on it ..

Help pls

A possibility is that the VIDEO selections you have made are too acute for the screen and Windows cannot continue (nor can it tell you it can't) so press F8 key while booting, select 'Last known Good' and see if that flies. Last known good is the settings for your PC that worked last time you booted. If that does the same thing, then reboot using F8 again and select 'Safe mode'

This will force WIN to use only known good settings, and then you can fix the problem by START, RUN and typing 'compmgmt.msc', choosing 'Devices', clicking the little + by Display Adapters, highlighting yours and hitting the DEL key. This will remove it and its settings from the Registry (but not the HD) and force Windows to reinstall and reconfigure it

Hope that all helps!

Power issue

Sounds like the Power Supply is gone or on the way out. This is caused by the Power Switch Transistor being too loosely clamped to heatsink allowing it to become too hot, and go into what we call 'thermal runaway' (2-3sec) and it draws too much current and the PS powers off to protect itself... or one of the capacitors responsible for filtering the recitified AC to pure DC (what electronics use) or frequency of oscillation of the switching supply (26-48Khz - ultrasonic) is drying up and changing value. A good tech can fix either. Most likely the big filter cap is bad, and AC (60hz) is getting thru and causing the transistor to switch erratically. This is a easy fix and the TRANSISTOR and CAP are $3.00 parts

Or the inverter in the LCD is biting the bullet. If you turn down the brightness, does it stay on or click on and off? THAT would be the inverter. Inverters take 5, 12 or 24v from the powersupply and run the itty-tiny pencil-sized florescent lamps that light up your screen. Lamps are $8.00 and inverters can be $50-80, but ebay has them for alot less

Hopes that helps
