my monitor shut down and won't come back on; keeps flashing, self test monitor is working properly, check cable connection; changed monitor worked for about ten minutes then did same thing, is there a problem with video card?

Have you checked your settings under Control Panel > Power Options?

What exactly do you mean by "keeps flashing"?

By "self test" do you mean the BIOS POST?

Is the monitor plugged into the video card or the motherboard?

the monitor won't come on for me to see anything; just keeps flashing

Shut it off.

Pull the power plug from wall.

Hold the power button "ON" for a good minute. (Unplugged!)

Then plug back into the wall & power on.

If you get past the BIOS POST start tapping the F8 key to enter Safe Mode Options



Boot the computer to "Enable VGA Mode".
Go to Control Panel, Add/Remove Programs.
- Find your video driver package & uninstall
While in Control Panel, go to System, Hardware
Device Manager. Expand (Click +) besides Video
-Any devices listed, Right Click, Choose Uninstall
Reboot the Machine - It will re-detect your video card
Re-install the drivers
Go back to Device Manager and change your monitor
definition to the correct vendor/model.

thanks I'll try this when I get home from work, will be back if there is any more problems.

it didn't work

Do you see your BIOS POST?

Can you boot into safe mode?

Not VGA this time but Safe Mode?

it's like when you turn on the monitor with the computer off all I get is no video error check cable

have you tried a new cable?

when you say: "keeps flashing, self test monitor is working properly, check cable connection"
do you ment the words: "self test monitor is working properly, check cable connection" keep flashing?
or what do you mean by: "self test monitor is working properly"

is the monitor plugged into the video card or the motherboard?

the monitor is plugged into a video card, "self test monitor is working properly, check cable connection" unplugged it from the computer, getting same message. took computer to my brothers house, computer is working fine. can't change cable unless I take monitor apart.
