My computer says "No Operating System" can anybody help me with this

Make sure its booting from the hard drive, but it indicates the hard drive isn't being read and may havew completely crashed.

I called hp and they said that it was fried are they right should I buy a new computer or a new hard drive

That depends on how old the PC is

My computer at least 2 year old laptop

Then I would just replace the hard drive

I am certainly no computer expert but I just went through a similar problem, only mine said Int. Exp. Is not working. I have been on the phone with dell for 3 days. It didn't solve the problem but one of the first things they had me do was to reload the operating system from the disk that came with the computer which took about two hours. They also suggested system restore but I had already done that. My problem turned out to be interference from start up programs. I am a novice. I can only say what happened to me.

This is a very big difference. With your system Windows was loading. With the OP its not reading the hard drive at all.

I understand what you are saying. Thanks.
