| 709461 | 2008-10-03 03:28:00 | Hmm. Often you get those kind of lines on a screen when a graphics card is overheating or the graphics memory is faulty. Does the lappy have build in graphics (Intel or whatever) or is it running a branded card? If you're unsure have a look in the device manager. I'd run a RAM test, although that isn't likely to find any faults, it can't hurt to be sure. NVidia Quadro NVS 110M |

| 709462 | 2008-10-03 06:03:00 | There was a thread on here recently about Dell laptops, with Nvidia integrated graphics overheating/burning out pressf1.co.nz perhaps a similar problem? Check this out direct2dell.com |

| 709463 | 2008-10-03 06:50:00 | Thanks for the info, could well be the case of a failed or failing nvidia GPU. | dyewitness (9398) | ||
| 709464 | 2008-10-03 07:52:00 | See the screenshot: www.imagef1.net.nz I have an LCD monitor connected to my laptop, and the last few days it's started having these red dot/lines, sometimes different colour, like cyan. On a dark background, they show up as red, on a light background they show up as cyan. Happens most often when clicking the Start Menu in Windows, where part of the menu are left behind as these dots/lines. Other info: - Samsung syncmaster 226bw monitor (maybe 6+ months old) - Toshiba Tecra M5 laptop, Windows XP Pro (2+ years old) - external LCD connected to laptop via VGA port So, is monitor on the way out? or display card in the laptop? or something else? Thanks. If you can take a screenshot of the problem, then it is unlikely to be an monitor problem, as you are taking a screenshot of what the graphics card is outputting, rather than what is being displayed on the monitor. |

| 709465 | 2008-10-03 08:13:00 | As above, since you took a screen shot it can't be your monitor. 2 years old Laptop, time to clean out the dust (as previously mentioned its probably over heating). Get the latest driver video driver (your's may be corrupt). I fix a lot of PCs and the odd laptop - it's surprising how much dust there is and how much things improve. |

| 709466 | 2008-10-04 11:51:00 | If it's bad enough to show up on a screenshot, then it's faulty/overheating GPU core or memory (or both) / stuffed drivers etc | Agent_24 (57) | ||
| 709467 | 2008-10-05 04:07:00 | Thanks for the input, hehe yeah should be picked up sooner that it was laptop issue not monitor... I did try the newest listed display drivers, no difference. The laptop has been off for a day or so and things seemed to behaving normally, does appear to be heat related. Problem is this laptop gets a heavy workout and heats up fairly quickly. I've never opened up a laptop before, how hard is it to do (also given that I'm not really a hardware guy)? |
