My dad has a Dell Inspiron 1100 laptop and I'm having overall problems with anything that has to be displayed on screen. By that I mean anything that moves there is problems, say when you close a window in XP how in the taskbar the others slide over to fit where the closed one was - well they slide about 1/3 of the way then pause and then jerk over. When I benchmark the computer (the rest of it; disk,processor, ram, ect) it benchmarks like I'd expect... fits right up with what it should according to SiSoft. My main issue is that I cna't play videos on it, I'd like to ultimately send that video to a TV and watch it on a bigger screen, but the video plays jerky... Now this is important I have fixed this problem before, but tonight doing what I remebered doing didn't fix it. So the problem is fixable without a reinstall/repair of windows. Here is what I have done in the past that fixed it, now I'm not sure which one of these did it, or in what order since it was quite some time ago, but here goes: I reinstalled the divx codec (I think...). I tried the video in WMP, Winamp 5 Alpha, and WinDVD I tried multiple videos, multiple formats (mpg, avi (divx type), and XviD) I tried reinstalling Video drivers I did Norton WinDoctor I did a Norton Disk Doctor scan, but canceled when it told me it required reboot if it needed to repair anything. I did the Windows chkdsk thing and did full surface scan and automatically repair things (ntfs drive so it takes 5 phases) Now somewhere in that it repaired somethign wrong with a couple *.sys files I believe and out of doing all that it worked fine, video played great and everything worked smoothly like it should. an interesting note before I go on in the task manager the SYSTEM process when the video was screwed up was using over 70%, when the video was fine after it was fixed the SYSTEM process used no more than 2% Tonight I had same problem as discribed above, and I did Norton WinDoctor, the full 5 phase disk scan, the reinstall of the vid drivers. None of that worked. Now I know fingers are being pointed to that I didn't reinstall the divx (it was actually an xvid codec but it includes divx - at least the one I installed did), but I really don't think thats the issue because any video type does it, and the system itself when it has to do any animation. So based on that does anyone have any suggestions for me? Please refrain from the repair/reinstall of Windows because I do not believe that is necessary in this case, and I don't like to use that as an option in fixing problems.
