Various random BSODs w/ different causes, booting difficulties, etc

Hello there guys, from the thread title you can already guess my issue is not simple. My computer is about four years old, and I use it intensively, so obviously sooner or later this would lead to issues.

For the past two weeks, I have been getting BSODs randomly, at first the cause was ndis.sys, which was caused by DAEMON TOOLS LITE. I uninstalled that and that specific BSOD was gone, but later, at random moments during gameplay I was getting strange "static-like" screens followed by BSODs, apparently caused by graphics driver. I have uninstalled the graphics driver and reinstalled it multiple times, apparently the BSODs stopped, but they came back and occasionally happen.

Yesterday it happened again, but then worse stuff started to happen. BlueScreenView points ntoskrnl.exe (BAD_POOL_HEADER) as cause for the most recent Blue Screens, and Windows started having boot difficulties, entering reboot loops (disabling auto-reboot results in an error). I have tried multiple things while in Safe Mode, HOWEVER sometimes I got a different BSOD even while in safe mode (the error was SYSTEM_SERVICE_EXCEPTION, as you can see in the minidump file). The recovery console doesn't work, triggering some kind of hard drive error. Today it has been VERY difficult to start Windows after a BSOD, I wasn't even being given the option to boot into safe mode, did various full shutdowns plugging the power cable off, and after multiple tries Windows just started normally.

I have a lot of stuff on my hard drive that I don't want to lose, and the amount of data is too big, which means formatting is not the best option here. I would really like to do a repair install, however my Windows 7 Ultimate x64 has SP1 installed, and my installation disk does not have SP1. I have tried to uninstall SP1 through Programs and Resources, but that caused my OS to "freeze". I need to get it uninstalled in order to do a repair install, right?

I have used the SF Diagnostic Tool and collected what I could. I'm currently in Safe Mode and after sometime I'm getting more and more BSODs and exception errors were happening. I'm attaching that data to this post. I also took two photos with my smartphone I was not able to transfer because Zune is not working in Safe Mode. I can try upload them later.

If I had to bet, I'd say my hard drive is screwed. But if it's salvageable, I would do anything to extend its life a little bit more :P

Thanks!

--------------------------------------
EDIT: List of repair tasks performed:

- Uninstalled graphics card driver clearing all registry keys and files associated with it, reinstalled it, repeated this process multiple times (currently the driver is NOT INSTALLED);
- Uninstalled the Catalyst Control Center (currently NOT INSTALLED);
- Performed complete power-draining shutdowns multiple times;
- Ran chkdsk (not through command prompt, will attempt chkdsk /f later)
- Tried to uninstall SP1 in order to perform repair install (unsuccessful, crashed while uninstalled through Control Panel, and resulted in an error while trying through elevated command prompt).
- Attempted using Recovery Console (unsuccessful, causes a BSOD or disk read error);


- Currently unable to boot outside of Safe Mode, BSODs ocurring randomly while in Safe Mode.
- Noticed motherboard drivers are out of date, I haven't messed with this yet because i'm not sure the issue is related to this.

Hi.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

If it does not show any error, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.

Edit: Plan to update the BIOS to Version 3029, too.

Recovery options give a disk read error (BSOD with just 2 lines of text).

Test the HDD using Seatools for DOS.
