XP locks up upon launching video or IE

Yeah, pretty shitty here.

Video thumbnails were locking me so i did the thing where you /u the dll for that.  stopped THAT problem but now video being played locks up.  also, now IE locks when i attempt to use windows update and see if that might help.  locks MIGHT eventually come out of it but my machine sucks and i'm not waiting all day for it so i've been resetting.

I have installed fresh video drivers, installed codecs, etc, nothing seems to be working so far.  help is greatly appreciated.

yeah so repair install didn't help either.  so it's hardware. guiess i get to buy new processor/mobo/ram
