    I've got a PC technical problem. Please help?

    I very recently encountered a problem with my PC. after about a few minutes when I'm in windows, i get these thin horizontal lines across my screen. but it doesn't end there, shortly after, i get these big thick yellow vertical lines all over my screen!

    I can still navigate my cursor but there's absolutely no point cause I can barely see anything!

    so here is the thing - its definitely not a monitor problem cause I've connected another monitor and the same problem still occurs. Ive been told to restore my computer back to factory settings but I dont think that will solve the problem, so its either that OR it could be a hardware problem possibly? graphics card maybe?

    can anyone help me out here?

    P.s. my computer is a new HP PAV... and ive head it for around 3 years now. my warranty is long gone.

    Is it a video CARD or are you using the integrated one that came with the computer? If its a card, try activating the internal (complete with swapping jacks as the internal will be on that other monitor jack), and see if the problem persists.

    If its already on the internal video, the on-board chip/processor could be going bad - the remedy is pretty much ADD a video card - which isn't such a bad idea anyway, as it frees up your RAM, and would improve your computer's performance.

    First things first though - figure out what your video source is - second, in either case, take the computer outside and blow the dust out of it - sometimes, that can cause issues with junk causing cross overs and bad images, not to mention simple overheating. (And you want to do it outside if possible, since why would you want all that clutter to just get right back into the machine again?)

    Let us know what you've got!

    As arknorth has eluded to, this definately sounds like a hardware problem / fault with your graphics card. If possible do the steps he has suggested, that will pretty much confirm or deny the problem.

    It could also be an issue caused by heat, a possibility as you say it occurs after a few minutes of logging in. How long have you had the machine and have you ever cleaned the dust out of it inside?

    I would start here as well, could be a heat issue, a dying PSU, or a failing GPU or even a bad/ loose VGA or DVI cable.

    What I mean is does the computer's video jack come from the motherboard, or is there a video CARD (litterally plugged into the motherboard). Integrated video (which most HPs come with) mean that 1- the video jack is usually up in the cluster of other jacks on the back of your machine. A video CARD is usually down below in the lower section of the back of your machine, and means that it has separate video jack - it also means that your computer would have greater video capacity. "Try activating your internal (video)" refers to turning on the motherboard's integrated video, and only means if you're not using it already.

    The question is first - does the computer HAVE a second video jack (where the monitor plugged in) on the back?

    This might be easier to figure out just what model HP Pavilion you have - any model number showing on the front of the machine?

    Okay - you've got more than you think - and you're STILL under warranty, but only just, since this particular computer came with a 3 year hardware coverage (It's the labor costs that have gone away). http://h10025.www1.hp.com/ewfrf/wc/...ry&lc=en&dlc=en&cc=us&lang=en&product=3574874

    What you have is a Vista-based Media Center, with all sorts of video options. On the back of the machine, is there a plastic cap covering a jack? HP sometimes does this to prevent someone from plugging their monitor into the incorrect video jack. If there is, this is your actual internal video jack. BUT - be warned - it is currently disabled, and using THIS jack will cause your computer to run slower, since using the internal video means using the computer's RAM Memory to operate it, taking it away from running programs, which is why there is a video CARD here as well. A secondary video card has its own memory, and frees up the computer's own memory to do its thing.

    IF you were to use the internal, BEFORE connecting the monitor to it, you would have to activate it. That would be done in the device or hardware manager of Vista. But before we go there...

    Since this is a Media Center, according to HP this computer should have installed in it a nVidia GeForce 8400GS video card with HDMI, DVI and all sorts of video OUT possibilities. Are you using any of these? Specifically, what type of monitor are you using - a regular computer monitor that plugs in with a large blue screw-in VGA jack, a Hi-Def monitor that plugs in with a black and white screw-in DVI jack, or an HD Monitor/TV using an HDMI plug that kind of looks like a really thin USB jack?

    Well, you have many options, depending on what you wish to do - as I noted above, your system is still under parts warranty (HP released to to your market on September 1, 2007 - assuming that you purchased it after that date, you technically are still covered for replacement of a bad video card).

    For the time being, you can still operate the screen through the internal video chip. As noted, you would have to activate it first. Go into your Device Manager -

    1.Click on the Start button and then Control Panel.

    2.Click on the System and Maintenance link.

    3.In the System and Maintenance window, click on the Administrative Tools link near the bottom of the window.

    4.In the Administrative Tools window, double-click on the Computer Management icon.

    5.When the Computer Management utility opens, click on Device Manager on the left side of the window, located toward the bottom of the list under the System Tools heading.

    Look under the Display Adaptors tab and click on the disabled video - enable it, then close all windows. At this point you should be able to shut your computer down, switch jacks on the back of the computer, and start up again. If the HP logo shows up, but nothing else (this particular reboot may take a few minutes to allow the machine to catch up to what you just did to it), you may have to reboot again and enter your BIOS screen (F1 or F2 at the HP Screen) and tell it you are using the internal video adaptor.

    Hopefully this will get you up and running.

    BTW - If you have an HD screen, and you're plugged into it using the VGA jack (that blue beastie), you're not in HD. You might want to invest in an HDMI or DVI cable to get that quality of image. Mind you, it could also cure what ails this video card as well, as that side of the card might not be affected by whatever is going on on the VGA side.
