laptop refuses to boo tup

[etegv]

hi, I recently got a laptop from a friend and Im having some trouble fixing it

I installed windows on it, but it refused to boot up properly once it had to reset. If i turn on the machine, I will see the dell logo for a second and then it just go black (this screen has a little blinking line)

I went into the bios and have the hard drive as the first boot priority. I dont know what else to do..

thanks for any help
