I am using a Acer ASPIRE ONE netbook w/ Windows XP Home Edition SP3 installed.

I did something stupid, I downloaded DirectX 10 for XP, and I thought "This will make the graphics on my computer look awesome" because originally, I had DirectX 9.0c.
So I installed it and I tried to play Republic Commando on it, and it said:
"you must have DirectX 9.0c to play this game" (not exact quote, but that's what it meant)

So I took action (maybe a bit to soon) and I tried to install 9.0c, it said that there was already a newer version installed (thus, DirectX 10). So, I COMPLETELY uninstalled DirectX, so now in the DirectX Diagnostic Tools, it says for DirectX version "Not Found", and now I can't install ANY version of DirectX (It says: "An internal system error has occurred. Please refer to DXError.log and DirectX.log in your Windows folder to determine the problem", in which, I have no idea where those files are)

I need help with this problem, any help at all will be gladly appreciated.

Use System Restore to go back to the most recent working restore point.

Thanks, already tried that before, it didn't work.

But it's alright for now, I think I by accident killed my computers bios. So I'm probably getting a new computer anyway (hoping an Alienware M11x).

Thanks for the help anyways!
