Laptop : compaq presario CQ45
when i turn on the laptop, it starts like usual and shows the compaq logo and then shows a black screen with a ' _ ' blinking at the corner then it goes blank for a second . then repeats the above process for ever.
i tired to diagnose using the sratup options and all tests were passed.
tried to remove battery and power to fully shut down and then restart again but the problem still persist.
please advice me on this issue.
thank you,
james.
