Radeon 9600 giving shuddering effect

    I have a Pentium 4, 2.8Ghz HP machine and have installed a Radeon 9600 256MB AGP card into it. The problem is that it seems to be giving a shuddering effect on the screen which is really irritating and is constant. I suspect it could be one of a number of things and am hoping someone here might point me in the right direction.
    Is it:
    - the fact that I have connected my screen to the VGA connection and not the DVI?
    - that the graphics driver is crap and needs updating (I got the latest from ati.com)?
    - that the GFX card is faulty?

    I also hear the fan of the PSU kick in noisely when I am running a few (light) applications and wonder if it is even up to the task. It is a 240w PSU, but I have only added one IDE drive and the GFX card to the standard system.

    At the moment I have it connected to a 32" LCD TV, but it will be used with a 22" LCD screen in the future. It's not a RAM issue as there are 2.5 gigs already installed.

    Shuddering in horizontal lines? Like a flicker you might see on an old TV?

    I would lay blame on the VGA port. Its a known issue with LCDs and VGA. Its an LCD right?

    Either way if the monitor doesnt accept DVI go ahead and connect the DVI cable to it from the DVI-port on the radeon and put a DVI-VGA converter on the monitor - one should have shipped with the card.

    Thanks Overheal. I am only getting back to civilisation now after the madness of Christmas. The shuddering effect seems to get worse the longer I have the PC turned on. Perhaps it is a virtual memory problem or something similar. Bizarrely, it seems to be running at 400MBs in virtual memory with just Windows XP running. I have never seen that before.

    Anyway, the DVI connection didn't like my TV screen (with the converter), so I will try it with an ordinary screen and see how that goes. Hopefully it will do the job.
