A few days ago, I installed the Abacus F-14D for FS2004 (for God only knows what reason - the IRIS F-14A/B is amazing)

Before I started flight sim to test it out, I was instant messaging someone on Facebook (using the browser Google Chrome), and AVG Free did a restart (I accidentally hit "restart now" instead of "Postpone")

And the next time I started flight sim, not only was the game slow, but the entire program was running slow even in the create a flight, settings, and all those other tabs and options.

I uninstalled the F-14, but I'm still having no luck.  I've restarted my computer multiple times, and its doing the same thing.

Does anyone have any ideas?  I cannot fly at 14-15 FPS

I'm running an Intel Pentium D processor, an Nvidia GeForce 8600 graphics card, I have 4gb of DDR2 667 RAM, a 600 (or more - I forgot) Watt PSU, and a hard drive with ample space.

I am not having problems with ANY other programs on this computer.

Thanks
