I have been having these problems with my computer for quite some time now and I have no idea what could have been the cause. Problem #1 When I have my music playing and I open another program, the sound like lags up real bad when its opening the program (like it is loading so much the audio cuts off at parts). This happens like with any program really, from firefox to dreamweaver. Some programs don't do it, like ventrilo. Problem #2 When my computer is running for a little while with some programs open (probably over an hour or two) it starts to freeze up momentarily. The freezes get longer and closer together until finally it either shows the blue screen of death or just stays frozen to where I have to turn it off manually. *** Sometimes when I start the computer it can't locate my CD drive, or my internal hard drive, or sometimes other components (like my external HDD). Please help me fix these, thanks very much!!!
