I have been working on a friends computer, a HP Pavilion DV6000 for a couple weeks now and have no idea what is wrong with it. The story I was informed of is that for about a year or so it was working more or less fine but recently (the past couple months) there had been some weird things the computer would do for a while then it increased over time so she gave up on it and gave it to me. When I got it it booted perfectly fine, I was even able to install some updates, the computer is running Vista Home Premium. When I shut it down for the night and booted it up the next day it did what she had described to me. When you hit the power button all the lights on the keyboard will light up but the main screen is totally blank and after about 30 seconds the power/lights shut off and about 5 seconds later it turns itself back on. And it did that every time after that. I thought the hard drive might be messed up but I had a spare around so that wasn't the problem. So I took it apart since I had heard from friends they had similar issues in which either the heat sync was messed up or the CPU was knocked loose for some reason. So I checked the CPU and it was locked in fine and there wasn't any thermal paste on the CPU so I put some on thinking that might do it but it didn't do anything. When I put it all back together I booted it up and it actually started but the BiOS had reset itself and there were some errors with the time and something else so I went in and fixed them and then when it tried to boot it went back to doing the typical thing of turning on for about 10 seconds then shutting off then turning back on. I gave it a rest for a few hours and tried again and still nothing. And I just booted it up now, about a day later and it turned on and said the typical Windows was unable to start what would you like to do. It might be a power issue but I'm not sure what it could be. If anyone else has had or is having an issue like this any advice would be great! I will try to see if I get any errors this time around and I'll post more information if I can get access without it turning off.

So after consulting with some people it seems as though it is an issue with the BiOS. I was told either I had to replace the BiOS chip (unlikely to do) or replace the entire motherboard (most likely). And while I know the chances or fixing this without replacing anything is minimal, if anyone knows of a way around replacing things then that would be great news.
