I took my HP 553w out yesterday to upgrade it and and give it a monitor, I put in 3 sticks of 128 ram and a 36-bit graphics processor, I got all this for 40$ cause I know this kid who interns at a computer bussiness he gets them for free and I get cheap deals....
Anyway. (After an hour of fixing some shit) I booted up Windows XP and it all went good, I then placed in my 2nd favorite game of all time: Morrowind 3, installed fine but it didn't play, it kept crashing out on an error message before it even started, well things got shittier from there, I can't do anything with my CD Rom drive now, it says (in device mangager) that everything is ok but nothing happens when I put in a CD, Linux/audio/games all don't work.
Wtf /=
Remove the CD drive from the hardware, disconnect it, clean the connectors, plug it back in, and re-add it to the hardware. See if that helps.
Goooooogle time!
I had this problem. Although theres probably less sacraficing resolutions, I reformatted.
