My problem is: I was on MSN when my computer began to LAG badly and seemed to be "locking-up." I shut-down my computer, I thought a restart would fix the problem. When I turned the computer back on, it went to the black screen that I have seen several times which gives the options, Start Windows In Safe Mode, Start in Network thinggy, Start In Last Known Working Configuration, Start Windows Normally and some other option I can't remember. I have tried starting in Safe Mode, Starting in last known working configuration AND starting windows normally. With each option I tried, it got so far as the Windows "loading screen." Then it would sort of restart again and return to the black screen. I don't know what to do. I need help Please! Thanks
