cooky 0 Posted April 23, 2011 Hello, I have started to see horizontal lines appear on the screen when viewing the cameras (see attached). When I look closely, the lines on one display are from a different camera image. The lines are not permanent, they appear intermittently, when I playback the lines are always recorded. The screenshots shows only a few lines, but sometimes the image is almost obliterated with horizontal lines. The PC is an Intel Core2 Quad CPU Q9450 with 4GB of RAM and a NVIDIA GeForce 8600 GT graphics card. The OS is Win7 pro 64bit. On one of the screen grabs, you can see a error message showing 'dvr error', I can't find any explanation in the manual explaining what this refers to; could it be linked to the horizontal lines? I have tried moving the NV3000 card to a different PCI slot, this stopped the lines for a couple of days but they have come back again. The card has worked fine for the last 18 months, can anyone help? Regards, Cooky Share this post Link to post Share on other sites
Birdman Adam 0 Posted April 23, 2011 How odd! How hot do the major heat-producing parts of the computer get? If the capture card was overheating, this could cause it to freak out. Verify the power supply isn't wimping out as well. Share this post Link to post Share on other sites
cooky 0 Posted April 25, 2011 I've attached a screenshot of the CPU temperatures, the graphics card runs at 76 degC. I fitted a 120mm extract fan to the rear of the PC case last year. I'm not sure if these are within acceptable temperature limits. Regards, Cooky Share this post Link to post Share on other sites
forbus 0 Posted May 9, 2011 I would connecto one of the cameras to a test monitor to see where the lines are actually happening. It could be a power problem as well. Are you using 12 or 24V? Share this post Link to post Share on other sites
