Hi, Im not really sure if im posting this is the right place or not, Im so sorry if im not. Here is a list of my computer specs: Operating System: Windows XP Professional Service Pack 3 BIOS: Phoenix - AwardBIOS v6.00PG Processor: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz (4 CPUs) Memory: 2046MB RAM Page File: 667MB used, 3271MB available DirectX Version: DirectX 9.0c (4.09.0000.0904) DxDiag Version: 5.03.2600.5512 32bit Unicode My problem is everytime i go to watch any type of video on youtube or other websites like that, the video will freeze i will still hear sound, then my computer will lock up eventually blue screening. i went to my system reports and found that i was having a nvatabus error, so i deleted everything to do with my nvidia card and reinstalled fresh, still having this same issue. I dont know what else to do. everything else on my computer thats graphic heavy runs just fine. i even play a game called second life, in that game we can watch movies streamed thru quicktime and i can watch those just fine. I hope theres somebody out there that can help me. thank you for reading.
