HP Pavillion a1520n/XP Media Center Edition 2005
PC seemed to work fine yesterday. Son said it "froze" last night so he shut it down by holding in the power button. Today when I tried to boot it, it takes me to a black screen that says "we apologize for the inconvenience, but Windows did not start successfully....." When I try to start it normally, it just goes through some processes and then comes back to the same window. When I choose "safe mode" it runs through some processes and comes back to the same window.
Please help!
Thanks, Karol
