Windows wont start up and give me BLUE screen

It is a HP Pavilion dv6000.
My friend's computer wont load into the windows. It keeps going to the selection where I have to select safe mode or start windows normally. I tried all the sections and they wont boot into the windows. I got the windows loading screen but then after it finished loading it gives me blank screen and then a few seconds later it gives me this blue screen.

I even went to the Bios to diagnostics self test my hard drive and it fails the test. (it says #1 - 07 Fail). The thing is she has a program calls QuickPlay. it loads before the windows to watch dvd, pictures or music. I use this program to browse my directories and it worked. I can look throught my directories and files but limited to images and music files. THEREFORE, I dont think the harddrive is corrupted. MAYBE some parts are corrupted, possibly the system files in windows directory got messed up.

I also tried to use Windows CD to repair the windows, i booted from CD at startup and it loaded everything and when i pressed R to repair, it shows "Setup did not find any hard disk drives installed in your computer," and told me to quit setup.

so weird.

i think the last thing she did was downloading limewire stuff. Theres possibility that she caught a virus that messed up the windows.

Anyone has an idea? plz help >_<

thx

I agree with Parkergrove. Hopefully you can re-install XP instead and choose the repair option so you won't loose all your previous programs.

Test with a different ram stick, if it boots fine then its your memory most likely, if it does it with a different stick then its then its your motherboard, that is if your sure theres nothing wrong with your hardrive.
