I have a HP Media Center with the Windows Vista platform. I purchased it in August 2007. Last fall I had an issue where my computer would frequently make noises and randomally freeze. Eventually it would not start up properly and a system recovery would not work. I contacted HP and they replaced my motherboard, free of charge in a 4 day turnaround. Unfortunetly I am experiencing the issue once again. I can not get past the 'blue hp screen' that gives you the option to system recovery or enter the boot menu. Is there any way I can fix the issue on my own or is my best bet to contact HP once again and hope for them to fix it again free of charge?
