First off, these problems have not always been around. Most of these problems have worked fine since i got it and have just recently started to act up. I don't believe i have a single problem on this computer that has existed for the entire duration of my ownership of this computer (school loan, got it brand-new last september).
My windows experience index fluctuates wildly from day to day, some days being 3, some days being 1, some days it will "update" without me even ordering one. Not the worst problem, because i know exactly what my computer is capable of, i don't need a space-wasting program to tell me what it can and can't do, but it still doesn't sit right with me.
A while ago Aero stopped working for no reason. It wouldn't show up on the Windows Color and Appearance list or anything. A system restore has resolved this problem.
*Biggest Problem, as of this writing*-Windows Movie Maker will not let me import Mpeg-4 files into it. It says i lack the proper codec, which isn't true, i have the most recent codecs, but just to humor WMM, i downloaded the codecs again, installed them again, and got the same error AGAIN.
Windows Media Player will not let me play DVD's on it, for no random reason. It says i need a codec for that, and as i stated above, i have all the most recent codecs (i update often).
I can download files at a speed of 30-some kbps, yet it still takes about 2 hours to download a 1 gigabyte file. Something's not right there.
This is all i can think of now
I know i am not the most knowledgeable person on computers, but i do consider myself better-than-average.
I use Windows Update regularly, have a good virus protection program, and windows firewall as my firewall.
Programs I have installed that i feel may (or may not) be affecting/causing the above problems-
Dexpot (Doesn't cause explorer to crash, but if explorer does crash, it prevents explorer from starting again, until i shut it down. Not a big deal, but may be a symptom of a bigger problem. Or not, idk)
Mozilla Firefox 3 beta (Just got it, so i doubt it, but it could.)
That's all i can think of.
Sorry this is long, but i've dealt with all of the problems i could, and this is the remainder.
