Games Won't Work After Reformatting PC
Hello! I'm a newcomer here, I'm really glad to find this forum, I hope I can learn something from my problem.
First of all, I'm sorry if my problems are stupid, I really have not much idea about PC. 
Well, the problems began after I reformatted my PC. I used Windows 7 64-bit Professional before, but the internet problem kept bugging me off, so I decided to install Windows XP SP3 32-bit Professional on my PC.
Games worked well when I used Windows 7. But then, they don't work after I reformatted it with Windows XP SP3. Steam even won't open. I downloaded Origin, and bought Battlefield 2 Complete Edition, but when I tried to launch it, it won't launch. Well, the desktop went black for a few moments, then it returned to normal desktop. I tried to install L.A. Noire, it won't work as well.
Sometime it also stuck in the black desktop, and when I opened the Task Manager, the BF2 didn't responding. Some other time, an error message popped out, "The instruction at 0x7c91240b referenced memory at 0x11cfc9f3. The memory could not be written.".
This is my computer specs, in case needed.
Intel® Core™ i7-3960X CPU @ 3.30GHz
3.30GHz, 2.94GB of RAM
NVIDIA GeForce GTX 690
I also have Microsoft .NET Framework 2.0 SP2, 3.0 SP2, and 3.5 SP1, installed.
I really appreciate any helps and suggestion! Thank you!
