Monitor going to sleep

I have a desktop PC that for the last 6 months keeps giving a beep & then telling me that the monitor is going to sleep. At first it was a little infrequrnt but no its all of the time. Every 5 minutes sometimes. I have all of the power settings to never turn off but it still happens. The PC works fine apart from this. To get it going again, holding down the sleep button on the keyboard normally wakes it up! If that fails just hit the reset button & all is ok again.

Does anyone have any ideas before I dismantle it for spares. Runs XP SP2.

Thanks John

Try another monitor, check cabling and socket/plug.

Hi have you checked to see if your PC has been set to hibernate?
'My Computer'
'Control Panel'
'Power Options'
'Hibernate' (Tab)
Untick the box 'Enable Hibernation'
'Apply'-'Ok'
It's worth a look!

I tried the new monitor & I checked all of the power settings & hibernate is not selected & it is still doing it!! I have swapped all of the cables with my PC & it doesn't make a difference. My PC stayed on without any issue with the different monitor as well.

Look for any power settings in Device Manager and Display properties in Control Panel

Are you sure that the problem is with the Monitor, and not with the Graphics Card?

In the power settings on control panel I have everything turned to "Never" as far as the monitor & PC are concerned. I can see no other settings that can be set.
As for the graphics card, I'm not sure. When its working, the picture is excellent. Fast response rate & no poor colour at all. My guess is its fine, but I don't know how to check otherwise.

How old is the mobo? Could perhaps be a failing CMOS battery.

From your description, perhaps not the graphics card - but one way to check is to carefully remove and then re-fit the card, making sure of a perfect fit.

My reckoning is, that if it is happening with more than one Monitor, then the fault is not likely to be the Monitor itself.
