Can anyone please suggest where I should look for the solution to my problem.

The monitor goes into standby without any warning in a totally random manner. Sometimes it is OK for a week and sometimes it shuts down several times a day.
The monitor cannot be awakened via the keyboard or the mouse and I have to use the reset button to make it work again. The computer runs normally (until I reset).

I don't think that it has anything to do with refresh rate or case temperature which never exceeds 30C.

It may be the monitor itself. Do you have another monitor to try out for a bit to see if it continues? If it isnt the monitor then I woyuld say it was the video card hardware or software. Make sure you have the latest drivers installed or use the original ones that came with your video card. If you have another video card to try that would be helpful too.

Thank you Mark.

It isn't the monitor itself. When I got the machine I hooked it up to my old monitor and after a few days that one shut down. I assumed that it had gone bust and bought a new monitor but when that too shut down I realised that I my old monitor was OK.

The video card sounds a good bet but I don't have another one to try. It's a Gainward on an Asus A7V8X-X motherboard.

I will look for a driver update. The card was pre-installed in my machine 18months ago.

I've got same problem with ATI AIW 9800SE. Monitor goes into standby mode without any warning but WinXP stays fully functional (there is no problem to restart PC by keyboard). I found that when I disconnect cable which connects PC and TV this problem totally disappear.

play some music on your computer and see if the sound goes off too when this happens. maybe your entire computer is crashing, not just the monitor.

I found that when I had my comp go into standby, if I moved the mouse to bring it out, it would automatically restart. Is yours set to go into standby?

Following my original posting I was advised to update the video card driver. I did this a week ago and have had no problem since but it is too soon to say that I have cured the problem.

I posted the original message about the monitor shutting down. On advice I updated the video driver and was OK for 2 weeks. Yesterday, however, the monitor shut down 3 times. The computer definitely continues to run during the shutdown because I can SAVE > START>TURN OFF>RESET to restart the machine from a shutdown. keyboard.
I once read (MS Knowledge Base?) that changing the power management settings helped but it is certainly not a permanent cure.

if u have a different vid card laying around give that a shot if u updated ur drivers and worked for awhile it would make me think u have a faulty vid card

I am having the same problem with my older computer that I use downstairs. It worked fine then started shutting the monitor off. So traded monitors, nope no good. Traded video boards, nope no good. Replaced the hard drive and yep that did it. I am not sure why. I even cleaned the old hard drive off and reformatted it and rebuilt my programs on it still would not work. I am wondering if track zero went bad on it? maybe someone smarter can help I am not that smart but it did work. or its been like that for a couple of days and working, anyway.

Indeed its all rather odd.

My PC has done this for quite a while. As such I have noted a few things.

I have tried shutting off all power management in the cmos bios settings. I have shut off all settings in windows. Still happens... Then for whatever the reason everything is fine, the PC will go months w/o it happening.

Yet... If I decide to pull the power plug out of the back of my 21" sony monitor, plug it back in... Guaranteed it will randomly just go into sleep mode. This is not a normal event. That is to say one can roll the mouse around, hit keys, anything one likes and the screen will not come back. I can shut the power off on the monitor, wait a few seconds, turn it back on and up it comes... Then moments later... back it goes into DEEP sleep mode. The indicator light flashed yellow. This is not a normal stand by event.

With that said... In looking at settings I saw that my Video card (a GE Force board) happened to be on the same IRQ as my network card for my cable modem.

I changed that around... no apparent difference.

I look back, the damned network card simply refuses to park itself in another IRQ!

Now I dunno if you folks have a similar issue.

That is to say YES my monitor will at times randomly go into low power sleep. But I can FORCE this to happen.

Unplug the monitor power cord while the PC is ON. Plug in back in a few secs later. Random sleep will happen. Now certain applications never happens, but if I launch a web browser be it Netscape, Opera, doesnt matter. The MOMENT it goes out on the net, whack, sleep mode.

I still have not figured out whats going on.

But... it appears to me that SOMEHOW a FALSE signal hits the monitor saying, "Time to go into suspend" and nothing will bring it back short of power off/power on and then it will happen again.

Its not the video card, I have had this happen with three different ones.

It is either 1. Some software anomoly or 2. Things get "out of sync" between what current system status really is and what the monitor or PC thinks it is.

The only OTHER think I can think of since my Network card and the video board sit on the same IRQ is that some packets coming in get misinterpreted somehow or another and the video board is getting some erroneous data that says, "Oh, lets put the monitor into standby".

I am not a hardware guru, I know some. I am a software guru (programmer) but not an "up to date" low level code programmer. When DOS/Win 3.1 were "it" yes, I knew the in's and out's of the hardware/software connection. With Win 95 forward I never bothered to stay in touch with low level code or the various hardware/software operations as it seemed moot since RAD development became the standard. I no longer needed to code anything in assembly language so I just lost touch with the hardware/software interfaces etc.

If anyone figures this one out I'd love to know the answer.

For that matter if anyone knows why my Intel 10 BT card REFUSES to sit on other IRQs even when I manually tell it DONT would be interesting.

In this one I am guessing the CMOS/Bios is basically overriding anything I care tell it or the card. In other words, since its a PnP card the cmos bios is saying, "I'll do as I please" because no code exists in said bios to allow for the other. That is to say one cannot buy a Network card that isnt PnP so perhaps the developers of the bios just dont support non PnP cards period. They'll leave that to specific driver/install software of some offbeat card rather than deal with it in any way shape or form in the Bios. In other words they will allow me in the CMOS to reserve an IRQ line but its up to a cards install/drivers to do the rest. BUT! If a card supports PnP then no matter what the user does the CMOS PnP bios say's, "Oh, I'll just do it!" and I have found no way to tell the card itself "NO! You are NOT to act like a PnP device!"

Could it be your power supply? I ask only because I am having this same problem and I just had to temporarily replace my defective 500W power supply with a 350W one.

My monitor is doing the same thing, and It started happening after I replaced my power supply as well.
