BSOD at startup

Hi. I started having blue screen problems yesterday. No hardware changes has been done.

Two days ago I was downloading some video clips and before I went to bed I put my computer in sleep mode and in middle of the night it put itself into hibernate as usual.
The next day when I turned the computer on I got the blue screen right after the Windows 7 loading screen and it at was there for several seconds but now when I start the computer its there for less than a second only.
Tried normal safe mode and with networking but after loading some files it freezes and after waiting nothing happens. I tried with command prompt but after the freeze I get double blue screens very fast before it restarts.
I tried to start the recovery things but after the vista looking loading screen the screen gets black for a minute and then the windows 7 backround appears and the arrow that I can move, but the recovery window itself doesn't appear at all. I havent done anything special that should or could cause this.

Another ****ing reason for me to get a mac...I miss XP so much -.-

Its 64bit and came preinstalled
I bought the computer in 2009 and last re-install is only 1-2 months ago.
My laptop isnt available atm so I dont remember much of the hardware other than its Intel Core i5.

Sometimes, these crashes happen due to the temporary memory being corrupted. Please follow these instructions:

1. Shut down and turn off the computer.
   
2. Unplug the computer from the wall or surge protector (then remove the battery if it is a laptop).
   
3. "Remove the computer from any port replicator or docking station, disconnect
   cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices." (Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English))
   
4. Hold down the power button for 30 seconds. This closes the circuit and ensures all
   power from components is drained to clear the software connections between the BIOS
   and hardware and clear any corruption in the temporary memory.
   
5. (If it is a laptop, plug the battery back into the laptop and then) Plug the computer back into the wall. Do not reconnect any unnecessary peripherals; monitor, keyboard,
   and mouse should suffice and be the only peripherals reconnected.
   
6. Turn it on to reinitialize the software connections between the BIOS and hardware
   

Im not home atm but thx alot for answer. Will try asap when I get home.

Did not help, tried it three times.
Forgot to mention that it's a Packard Bell Easynote TJ76 laptop.
Maybe something is different on it?

Registry Replacement:

A coworker had a similar problem. These are the steps I used to resolve it:

You will need a Windows 7 repair disc or you can use the Advanced Boot Options to get to the System Recovery Options.

Then try the steps in Startup Repair Infinite Loop Recovery. Note the warning:

   Warning

The instructions presented withing this tutorial must be followed correctly, or you can damage your Windows 7 installation even further. This tutorial is designed to help recover from a bad registry that is causing the startup repair loop. You should note that there may still be some issues remaining that cannot be fixed by manually restoring the registry.

Then do the same steps as in my previous post to clear any temporary memory corruption:

1. Shut down and turn off the computer.
   
2. Unplug the computer from the wall or surge protector (then remove the battery if it is a laptop).
   
3. "Remove the computer from any port replicator or docking station, disconnect
   cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices." (Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English))
   
4. Hold down the power button for 30 seconds. This closes the circuit and ensures all
   power from components is drained to clear the software connections between the BIOS
   and hardware and clear any corruption in the temporary memory.
   
5. (If it is a laptop, plug the battery back into the laptop and then) Plug the computer back into the wall. Do not reconnect any unnecessary peripherals; monitor, keyboard,
   and mouse should suffice and be the only peripherals reconnected.
   
6. Turn it on to reinitialize the software connections between the BIOS and hardware

Loose Hard Disk:

If you are unable to get into the Recovery Environment with a repair disc, there is more at work with the laptop than just a software issue. It would not be a Windows problem but a hardware problem. The first one I would suspect is a loose hard disk.

The first thing to check is whether the hard disk is physically connected to the motherboard properly. To do so:

• Shut down and turn off the computer
• Remove the AC Adapter
• Remove the battery
• Hold down the power button for 15-30 seconds to close the circuit and drain any residual power
• Remove the panel on the underside of the laptop where the hard disk is housed
• Remove and re-insert the hard disk by sliding it away from the connector and then gently but firmly pressing it back into the connector (no screws should need to be removed to do this step)
• Replace the panel on the underside of the laptop to cover the hard disk
• Replace the battery
• Replace the AC Adapter
• Turn on the computer and see how it responds

Post back once these steps have been implemented whether the system is stable. Sometimes these crashes can occur due to a loose connection.

Trying to repair the computer by pressing F8 and Repair Your Computer was the first thing I did, but the window itself never appears, only the background and the arrow.
I had a USB flash with W7 but I tried to look for it yesterday but I didn't find it.

Ill go buy a repair disc if it's not too expensive or Ill just borrow one from someone.

EDIT: never mind, I stood up from the chair and there, right under my bad, the USB flash was lying there
Just gonna fix BIOS settings and try :)

What a fking disappointment..
It boots from the USB stick. I clicked on repair your computer and then on startup repair but then the window disappears and im left with the background and the arrow.
I tried again but then I didn't even get further than Repair your computer.
I tried to install Windows instead but freezes at Setup is starting... or something like that.
Im so tired, Ill try the other options about flashing Windows Defender Offline tomorrow and then the loose harddrive guide.
But thanks alot for trying to help though.

Can you backup your system with Ubuntu? Desktop | Ubuntu -> Install Ubuntu Desktop | Ubuntu -> At step 2, choose Try Ubuntu instead of Install Ubuntu. See if you can access your files and back them up.

You can also run a disk check through Ubuntu: https://help.ubuntu.com/11.04/ubuntu...isk-check.html -> Disk Utility -> Check Filesystem (lower left corner of Disk Utility).

Tried Bitdefender and Avira rescue CD on USB stick, it just told me BOOTMGR is missing...

Gonna try Ubuntu then

BOOTMGR is missing when trying Ubuntu too. Only the USB stick with Windows 7 loads..
Any way to fix this?
And Im not so sure about if it actually did hard reset because after I tried that, I still got the message at startup about Windows starting problems etc..
Any other solutions?
Could any hardware be damaged?
Did I lose my guarantee when I opened the laptop from the underside?
I didn't do amything because there wasn't anything to slide there.
