Hello, and thank you for deciding to check out this thread. _______________________________________________________ -PC Specifications- Processor: AMD Sempron(tm) Processor 3400+ 2000 MHz Memory: 512 MB Motherboard: ASUSTeK Computer INC. K8V-VM Video Card: Radeon X300/X550/X1050 Series Windows: Windows XP Professional _______________________________________________________ The title explains some of the story, but I'll give you a detailed explanation. Like two or three weeks ago, my PC started to act weird. The monitor shut down and became unresponsive, and I had to reboot. A few days after, it happened again. Then shortly after, the screen's icons started to become overrun by colored dots and then the screen shut down again. I tried to restart a few times, then set automatic restart on system failure OFF. Once I tried to boot the PC, the dots appeared again but then received a BSoD (Blue Screen of Death), saying ATKDISP is causing system failures. I don't remember the shut down codes and such - I tried to fix the problem at the times when the PC's monitor didn't shut down by using RegClean Pro and such. At some point, I couldn't boot the system at all - the dots kept appearing and then the BSoD... Oh and few days before this incident started to occur, I updated my system to Service Pack 3 and didn't have many problems, so I don't think that's the issue. After several attempts to fix the problem, I ran the PC into Safe Mode and used a backed up registry, which was pretty old. After that, the PC couldn't boot at all anymore, it kept restarting. Well, I was pretty desperate at that time and didn't even remember that registry was at the time when I had Service Pack 2. Well, the incidents above aren't so important right now to me, because... I re-installed Windows, and then the problem SEEMED to be fixed, but when I installed Catalyst Control Center, ASUS Enhanced stuff and such, then restarted and then the problem occurred again... I ran into Safe Mode and disabled Display Adapters from Device Manager. After that I could boot Windows but I can't run any games, since I have the video card disabled. After that, I used Driver Genius Professional to update the Display Adapters. But then when I enabled them, problem was still there. Today I even opened up my PC and removed any dust, but still the same results. Like a few weeks before these issues began, I downloaded ATi Tray Tools and installed them but then none of my games could work, so I uninstalled it, if this info is helpful in any way. I am starting to think the monitor itself is the problem, because I can still hear sounds when the dots appear then screen turns black then milions of colored lines appear, but I do not receive any BSoD anymore. If you need any additional info, please ask. As you can imagine, I am most displeased about the current situation, so any help would be much appreciated - sorry for the long post, and I apologize if I posted in the wrong place. I will be able to get a new PC in 2 or more months, and until then I'd have to find a way to fix this one although it's pretty old. Thank you for reading.
