Laptop has trouble starting up.....

[Tito Jackson]

When I turn on my laptop (new HP VIsta Home Premium) it powers on then off like 4 times before it finally turns on and begins booting. It's like it is struggling to start up and takes forever. Checked to see if my ram was seated properly and they were. Any ideas what the problem might be. I'm hoping it's not a faulty hard drive or something. I already had to send in the DVDRom because it stopped working also.
