Greetings.
For a month, I'm trying to solve a problem on my pc, but I don't know what is causing this, never encountered anything like this.
I will tell my specs, explain the problem, show the steps I have taken trying to solve the problem. Hopefully someone can solve this problem without reinstalling windows.
Specs:
Windows Vista Home Premium 32bit.
Nvidia Geforce 9600 GT
DirectX 9.0c, though I had DirectX 10.2 installed but it disappeared.
Latest windows update installed.
Issues:
The following problems occur:
1# When booting, I get a run.dll error about 'nvcpl.dll'. Forgot the text, but it was something with unable to reinitialize. Nvcpl.dll is related with the Nvidia driver.
I can play most of my games though.
2# Nvidia control panel doesn't start when I want to use it. It's still in the User Control Panel, but it doesn't work.
3# Missing DirectX files. When I want to play a game, I get many errors like: 'Cannot find d3dx9_24.dll...' Those files are in the %Windows%/System/ directory. I don't mess around with the Windows folder.
4# Software stopped working. Most of the software I use(Windows Media Player Classic, Nvidia control panel as I mentioned, other scanners etc.) stops working without me having done anything.
Sometime, the program is removed from the list with programs and software, but the program is still on my pc and functions. And the other time, the program is in the list with programs and software, but it doesn't work.
5# My pc thinks the internal hard drive is external. The icon 'Remove Hardware Safely' is showing that my hard drive 'C:\' is external. That doesn't make any sense. I don't even want to know what will happen if I 'remove this hardware safely'.
6# Random booting problem. When I reboot, sometimes, Windows ask me if I want to run in safemode etc. Like it didn't shutdown correctly. That is not supposed to happen.
Steps I have taken trying to solve this:
*Full scan with AVG Free, Lavasoft Ad-Aware, Malware Bytes Anti-Malware, Registry Mechanic, Combofix(followed by their instructions, bleepingcomputer.com). And some other scanners.
All of the above did not help.
*Reinstalled Nvidia driver software and DirectX 9.0c.
My pc is fine for...12 hours, then the problems appear again.
*Installed all the windows updates.
Did not help.
*Manually downloaded some of the .dll files.
Problems will appear again in about 12 hours.
*I did not removed/uninstall any software that could be causing this.
Conclusion:
I have no idea what is causing this and I'm hoping someone can help me.
Reinstalling windows is the last thing I want to do, I have to make huge backups. If you have a flat tire, will you buy a new car? This could be solved I believe. Thanks in advance.
