HOW CAN I FIX THIE ERROE (0XF78d2524,0XC0000034,0X00000000,0X00000000)
That's not the entire message - does it have 0x00007b in front of it? If so, it's some form of booting problem, possibly caused by the wrong hard disk driver. Is your installation of Windows 7 a new one or has it worked properly before? What is the name and model number of your PC?
