newbino Posted April 21, 2010 Share Posted April 21, 2010 (edited) Hi, I am not sure how to describe the issue so all my googling has been in vain, I hope you can help. I am not even sure which section to post, I assume it's software-related but maybe it's not.I am running Win 7 with Asus p5K motherboard 4GB RAM NVIDIA GeForce 8500 GT.Since yesterday (no new installs) when playing videos occasionally red or/and short squiggly lines appear for a few frames - kind of flash-like - and disappear. They return in different parts of the frame at irregular intervals. Could not make screens as in KMPlayer scrolling between single frames the lines appear to be inter frame (appear only on the scroll between two frames but in neither of the two).I am also noticing a similar event, this time covering all the monitor which much longer lines, at boot. Specifically, after I input my password.So far I have ascertained that:1. it's not a problem with the files themselves - I am having the issue also with older files which I have already viewed without pronlems2. it's not format related - I am having it with all the formats I tested: .avi, .mpg, .mp4, .flv3. it's not player related: it's occurring with KMPlayer, Media Player Classic - Home Cinema and VLC portable which I just downloaded for a third optionI have attempted the following so far, without having any results:1. rebooting2. uninstalling all codecs and reinstalling the latest K-Lite Codec Pack 3. updating the NVIDIA drivers4. checking device manager As I mentioned, I have been unable to google for the problem, as all description I have come up with appear to produce unrelated hits.

DigeratiPrime Posted April 21, 2010 Share Posted April 21, 2010 If you're getting the problem at boot its not a windows issue, rather hardware. My guesss is probably the video card or monitor.Moving to the hardware subforum... Link to comment Share on other sites More sharing options...
John305 Posted April 21, 2010 Share Posted April 21, 2010 Hi well the first thing to check is what temp is the card running at you can download EVGA Precision and it will give you the temp. Link to comment Share on other sites More sharing options...
Semangka Posted April 21, 2010 Share Posted April 21, 2010 I think it is a hardware failure, basically it came from overheated GPU on a long time run. Can you post your GPU temp? Link to comment Share on other sites More sharing options...
newbino Posted April 21, 2010 Author Share Posted April 21, 2010 If you're getting the problem at boot its not a windows issue, rather hardware. My guesss is probably the video card or monitor.Moving to the hardware subforum...Turns out that DigeratiPrime's guess was right, the problem lies with the monitor.I had totally forgotten (duh!!) to test my secondary monitor (I run a dual monitor system) and sure enough on it I had no problem playing various video files or at reboot.Dell has arranged to substitute the faulty monitor (still in warranty) within 48 hours - fast procedure, hassle-free, so it appears that everything is solved.Thanks to everybody for the help!
