Lenovo G505 HDD & CPU fan problem

[vagdal]

Hi guys!
a friend of mine gave me to fix her lenovo g505 laptop that stucks at lenovo start screen.
I heard a noise from hdd so I remove it and I checked that is dead. Also the gpu fan starts when I turn on the laptop for about 30sec and then stops.
My question is if we replace the fan and hdd is going to work or it could also be problem on cpu?

If the HDD was dead, its probably safe to assume that that is the problem.

I don't think that the GPU fan turning on is a problem, just replace the hdd (an SSD would be a fabulous upgrade if she wanted to spend the money)
