Thanks for the reply :
- no. i think im not making any changes before my laptop is having the issue
- no. i dont see any error messages like bluescreen or something
i try to do the advanced startup options that you suggest. but it doesnt show the menu. is pressing the F8 button is before the "bios screen" or after it?
btw, thanks again for the reply. i really appreciate it. and sorry if my english is bad and a kind of rude. im from indonesia
waiting for the next reply..
