When I reset the cmos some how it displayed Pentium 4 log window and stacks there before I reseted it the monitor goes from green to orange while the pc is on. I changed the RAM but no change and when I remove the RAM totally, it beeps I have two RAM installed. cdrw and DVD players led blinks when I start the pc. This problem started after windows installation failed so many times by displaying ntfs.sys missing. then someone told me this may be due to RAM so I removed the RAMs and installed it again as he told me and thing worst.
