PC will start up and monitor green light comes on, then turns to orange and screen remains black. nothing else happens. PC cd drive will open fine, but no monitor and no XP screen. If I push one of the screen adjustment buttoms, the screen will momentarily come on and say "in safe mode; fix this from PC". Already tried taking the coin battery out, no change. This is Dell optiplex 755, only yr old.

Do you see the BIOS splash screen or anything?
Try booting into safe mode by pressing F* as soon as you power on the computer. If the monitor works, then it is a bad driver. Roll back to a previous restore point, boot to last known good coonfiguration. Last Known good configuration is available from the same as the safe mode screen.
If this is helpful, please comment and rate. Have any other questions, please let me know.
Try booting the pc in safe mode (press f8 at startup). It may be possible that the pc is trying to send too high a resolution to the monitor...unlikely though. The symptom you describe usually indicates that the power board or the inverter board in the monitor are defective. If it does the same thing in safe mode, you have 2 options.
1. Replace the power board and inverter board (do the inverter board first.......it's the cheaper one (10-20 dollars). 2. Send the monitor back to the seller for a refund, or get a new monitor.
Sorry I couldn't give you more positive feedback. Hope this helps.
It could be your monitor is fine. It simply goes to a cycle when its turned on and does not detect any signal coming from your CPU, it simply goes on standby mode (hence the darker image and orange/blinking light.) have you checked the computer (CPU) part?
ok, get to the event where you get this to happen "...then turn it back on the monitor does come on normally...", but just after power-up, press the F8 key to go to safe mode. If nothing visible, press ENTER anyway...get to safe mode yet?
There must be a connection problem from monitor to pc, check the pins to see if any are bent in the plug to the pc.
If it is a seperate graphics card, check that it is seated correctly in the agp (brown) slot and not come loose.
Try booting in safe mode (F8) on boot and select boot Windows in safe mode(this will run pc with normal vga driver and not the graphics driver), and see if it stays on, if it does it is a graphics card driver fault, so re install.
