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.

If all diagnostic lights are on, then that means that it has something with the software of your computer. The update has affected some of the programs inside your computer thus it's booting up fine.
I suggest that you access safe mode and do a system restore from there. If you don't know how to access safe mode, then follow these:
1. Turn off your computer. 2. turn it on and keep tapping F8 until you see the options. You should see safe mode. 3. Use the arrow keys to select safe mode, then press enter. 4. Your computer should boot up to safe mode. 5. Access the system restore. You can find it in accessories, system tools, system restore. or you can search. 6. restore your computer to the known good date where your computer was still working fine. 7. After completing the on screen procedures, let your computer restart by itself (it may take minutes or more). It will restart and it should boot to the normal windows.
Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.
The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.
Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.
Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.
Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)
Go into safe mode Under settings, control panel, power options set "turn off monitor to never reboot
I think this is not a sleep problem but the incorrect monitor settings were set. This will cause the screen to go black when the OS comes up. Boot in safe mode and change the display settings to 640x480 OR in safe mode, delete your monitor. When you reboot it will load a default monitor and you should be OK
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.
From your description, you were able to boot the machine properly in Safe Mode. While in Safe Mode, change the video resolution to the lowest possible (color depth does not matter at this point). You should also check that you are configured for single monitor operation if your video card supports multiple monitors. Reboot the machine normally. If all goes well, you can readjust your video settings for a higher resolution again.
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?
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.
