Hallo Lenovo G560 Startup Loud Noise

[syneresis]

Hi everyone,

I have Lenovo G560 with WIN 7 installed on it. It makes a very loud screeching noise when it is starting and if I let it start that way, it boots with this continuous loud sound and then it works normal once it is started.

I would appreciate any help.

Thanks in advance..

It sounds like a bearing going on a fan. Is there any tapping noice or just screeching then silence once it warms up? Have you noticed it getting any warmer underneath or is it slowing down at all as you use it more? Like bringing up a web browser or a program?
