lrbarrios Posted January 15, 2008 Report Share Posted January 15, 2008 I'm having a very strange and annoying problem with my Dell Precision M50. For the longest time, everything ran just fine. The other day, I started getting video corruption (flashing or 'static-like' vertical lines, discoloration, blocky appearance, etc.) while in Windows. I would reboot and everything looked fine, until I pressed Ctrl+Alt+Del. The moment I applied pressure to the keyboard, the screen would freak out, sometimes locking the computer up. I then went into the F2 Setup BIOS and noticed that every 4th character was missing from the text screens. Sometimes characters would be there, but they were mis-shaped (e.g. an 'M' may have a couple of pixels missing from the right side). In the case of the mis-shaped characters, if one letter was mis-shaped, ALL occurences of that letter would be identically mis-shaped. I could also see the vertical line issue on this screen. I know it's NOT a Windows driver issue. If I connect an external monitor, it will also show the same problems. I opened the case and found the video adapter. It was quite hot and even had a 'hot smell' to it. I reseated it and powered up. Same problem. With the case open, and the computer showing the problem, I started applying pressure to various areas of the laptop. When I did this, the problem would start and stop. Almost everytime I pressed on the video adapter, the vertical static lines would start to appear. When I stopped poking around, the lines would stop. Sometimes, however, the lines will just start on their own. Everytime I launched World of Warcraft, there was major video corruption at the title menu (sometimes crashing the computer). All of this led me to think that the problem was the video adapter. I purchased and received a used adapter from eBay. I've installed the 'new' adapter. After the computer booted up, everything looked fine. Launch WOW and it crashed. When I could finally get Windows to boot again, it said that it had just recovered from a serious system error and it mentioned the nVidia driver as being the problem. Sometimes I would get a Blue Screen of Death saying the same thing. In these cases, I think it has something to do with the 'new' adapter. I've put the old 'suspect' adapter back in the laptop. I booted it up and have been watching the temperatures. The CPU and GPU, both, never exceed 150 degrees at 2GHz and 75%+ CPU load (virusscan and WOW simultaneously). It ran flawlessly for at least 3 hours. I thought maybe this was just a case of a loose connection and reseating the old card (again) had fixed it. As soon as I moved the laptop, the video corruption appeared. Everything has started all over again. Am I dealing with bad video memory (where is the video memory and can it even be replaced). Or is there possibly something else going on here (perhaps a fracture on the motherboard). Any help or suggestions please!! lrbarrios :) Quote Link to comment Share on other sites More sharing options...
