hp Pavillion dv9000 cd laufwerk und überhitzungsproblem

Hi,

since the warranty is expired, I am only experiencing problems with my 
Laptop! First thing that happened, it is overheating extremly that is 
shuts down itself and I have to wait for about 20 minutes until I can 
restart it again. The van is clean, there are no worries about that. 
However, since my laptop is overheating extremly, I think it burned the 
connection between the Laptop and the disc drive. My disc drive is only 
opening, while I am starting my Laptop new and when it is all uploaded 
and I want to open the disc player, it is not responding. My Laptop is 
not even showing that I have a disc drive! It is really frustrating.

Another problem I am experiencing is that my Laptop is not able to load 
up without problems, it keeps getting stuck while loading it up, it does 
not work. I have to keep restarting it until it eventually works again. 
I have no clue in what I can do about that. I ran the AVG and Norton 
virus programs and they do not find any viruses.

Help is needed really bad!!!

Thanks
