Will not boot

[busdoc]

My dv9640us crashed last week while I was on vacation. I got an error message stating a kernal was corrupted and to insert recovery disc. I had to wait until I got home. It took two or three trys to get it to boot up with the recovery disc. After it loaded, it proceded to reformat and install Vista. I waited for it to go through all the stages, but in the end, I got a message that Windows did not install correctly and the computer shut down. I have not been able to get it to boot up since, with or without the recovery disc. Any suggestions?

Sounds like your hard drive may be bad. Try running the hard drive test available in the BIOS.

Thanks for the info, but I will not be able to check the hard drive via BIOS since the computer will not boot up at all. Your answer does confirm my suspicion that I have a hardware issue.

So your computer does not turn on or turns on but nothing displays on the screen?

Adamtech,

 Thanks for your help. The computer turns on, but I only get an 1" line at the top of the display. I called support and I am sending it in under the extended warranty I purchased.
