Computer is driving me crazy

I have had numerous BSOD over the last couple weeks. I have tried disk check, memory diagnostic, system restore, driver updates, etc.

Last night, I decided I would try updating to Windows 7 in case there was some compatibility issue, and it wouldn't allow it because it stated SP 1 was not installed. Windows update states that it has installed successfully, but the system information doesn't show it as being installed. When I go to refresh my system update and check for new updates, it comes up with an error.

Does anyone have any ideas? I have attached some recent memory dump files if anyone can work with those.

Thanks!!!

1. When you are under black screen condition, if your mouse and keyboard are still usable, and you are lucky enough to have a dialog window (usually "My Document"), use this window to go
Cor whatever drive that stores your operation system) -> "Windows" folder -> find an application called "explorer", double click and open it. Now you should be able to get your screen back to normal.
2. If you don't have a dialog window, press "Ctrl" + "Alt" + "Delete" together and transfer the screen back to the login page. Click "Task Manager" -> Click "Application" tab -> Click "New task" -> type in "explorer" and then press "Enter" key. Now you should get the desktop screen.
3. Press the Start button (the one with window icon, at the lower left corner), open the "Run" program (if you can't find it in the menu, type "run" in the search bar and search for it). Type "regedit" to open the registry editor.
4. Go to this root:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\System
Under this root, you should see a item named "Shell", if the data value of "Shell" is "C:\Windows\Explorer.exe C:\Windows\system32\tlntsvi.exe", here is the MALWARE!
The correct value should be "C:\Windows\Explorer.exe" only, whatever following this command is the bad guy that brings your computer to black screen of death.
5. Now MARK DOWN the NAME of the malware (in my case, mine is "tintsvi.exe"), because this malware is known to have different names. So far I've seen "tintsvi" and "pnkx".
Now delete whatever command that follows "C:\Windows\Explorer.exe". Close the registry editor.
Start "Search" program, type in the malware name (in my case, "tintsvi") and search the remains of the malware. You SHOULD find something in the "Windows" folder. I've found a "tintsvi8973.exe" application as well as a weird file called "Servx.exe" under "C:\Windows\System32" folder. Since "servx" and "tintsvi8973" were created at almost the same time, I believe it is a malware
6. Restart, the black screen problem should be solved.
