I'm not sure what caused it. I just reformatted today and when I finished installing everything I needed I noticed this problem. I don't know exactly when it happened. Here's my computer specs:
Windows XP Pro SP2
AMD Athlon XP 2600+
MSI K7N2 Delta L+
ATI Radeon 9800+
I'm sorry if there is already another thread about this. I wasn't sure exactly what to search for. I also apologize if more information is needed. Any ideas?
