I also used to challenge with this problem. But I found the reason that I have a problem with my monitor, not from the virus. The reason is my monitor is very old and it has a problem with the circuite inside the monitor. Try to check the power light on your monitor. When the monitor is turn off, is this light is become red or turn off too. For my case, my monitor light become red light like the time that I just turn the power on. But one more thing that might interrupt you that might came from the virus too. In my opinion, the virus might act like a serivce that turn off your monitor every period that it reach its time limit. You should check in your system or search on the internet to find the virus name and clean it from your computer.

If this happens when you have not been using the keyboard or mouse for several minutes then then check the power settings on the control power, it may be setting the monitor to standby. Elaine :rose: The tigress is here :-D

There's really no virus that is known to do this. It's just not damaging enough, I guess. But, where I work, I've replaced about 30 ViewSonic VX900 LCD's in the last 8 months because of problems with the backlight. After about a year, they just started dying, probably because of bad capacitors in the backlight power supply. The backlight would work for anywhere from 1 second to 20 minutes before it died.

Assuming you're using a CRT (they do not die after a year). Does the monitor actually turn off or just go black. I heard about a virus that painted the screen black when I was working with Win3.1 - I don't know if it still exists. If you have anti-virus installed (as you should - http://www.free-av.com) then try another monitor.

Really? On what planet? I had two of them die inside of a year...

It wouldn't even be passed around today. Unless, of course, this person is still using Windows 98 or lower... And make sure you check which message your Replying to before hitting the "Post message" button... Dave Kreskowiak Microsoft MVP - Visual Basic

Sorry, Next time I'll just not bother trying to help. Viruses written for Windows 95 (and compiled in 32bit) can still have an affect on XP FYI.

Yeah, I know. I've been doing this for nearly 30 years now. In your post, you didn't mention anything about Windows 95, you said Windows 3.1. Viruses that worked under DOS and Windows 3.x normally spread themselves by infecting the boot secotr of floppies and hard drives. They don't work under NT Kernel O/S's because the boot loaders are very different and the permissions required to get low-level access to the media to spread themselves wasn't available to them. Also, those viruses were written in 8 and 16-bit code. Most of which just doesn't work under and NT Kernel anymore... What FAR more common now-a-days is to spread by email. Even then, just turning off the monitor isn't a juicy enough target today. That's just merely annoying. The current target is turning your entire machine into a zombie that can be remotely controlled. But, yes, viruses that worked under Windows 3.x and 9x CAN still work, IF they a machenism to spread that is still in use today AND IF the environment that these viruses need to execute is still on your machine, which is far less likely in an XP world. You can help all you want, just make sure your replying to the correct post. Since you didn't reply to the original poster, he/she did NOT get an email that said you replyed to when he/she posted. The only person that gets an email that you replyed is the person who's post you replyed to. Dave Kreskowiak Microsoft MVP - Visual Basic
