Just bought a used Compaq Presario. The monitor keeps turning on and off. I have checked all connections and tried different power cords. Still the same.

Re: Monitor keeps turning on and off

OK All these Compaq's have a Power Supply problem, or a Horizontal Voltage problem.. meaning they are on the way out. The SMPSU's in these units often fail along with the Horizontal Drive Circuitry. I think it is time for a new one? Repair of such a unit would barely be "Ecconomical" IMHO.

Will a hp vp17 monitor work on a compaq presario?

All monitors will work on any pc/mac computer.
The only concern might be how old is the monitor (low resolution) connected to a brand new computer (high resolution). But it usually auto adjust at windows boot up.
Check the VGA connector (blue) or DVI connector (white) for the monitor matching the pc tower

Will a hp vp17 monitor work on a compaq presario?

Yes, I think so, if the video connections are compatible. If they aren't you may need an adapter, or, there a very slight possibility that they are not compatible. You don't give the model of the Presario

You don't really update the drivers for your monitor. If you want to update your video drivers. I'm guessing because it's a Compaq Presario PC that it uses Integrated Radeon graphics acceleration so to update those drivers go here. Once there you will need to select Integrated Motherboard Graphics in the first block. From there on I will need to know the exact model number of the Compaq PC to proceed.

Press a few buttons on the keyboard incase the computer is in sleep mode.

If you still don't get picture at all, the issue is with the computer, please test the screen on another computer to see if the problem persist there, if it works perfectly on the other computer then theres a problem on the computer and I suggest you get someone to look at it.

I'm having problems locating a manual. Compaq doesn't seem to support the model anymore. Reading a review online, It almost looks like Compaq had an Application control this instead of practical buttons on the front. Here's the review I read that talked about it ->
Hope this helps a bit! Sorry I don't have much else, I've been digging for a few days now to find more.
