The problem I am having is that when Windows is loaded, and I do a couple of benchmarks, it shows that my PC is running slower than what it is supposed to perform at. Example: My Setup: AMD Athlon XP 3000+ FSB333, Kingston 1gig PC2700 RAM Benchmark Results: Performs as AMD Athlon XP 2000+, PC2100 RAM. Also, When the PC is on, theres a faint screeching noise coming from the CPU. Now, i know the CPU and RAM are fine because they worked like a charm on a previous setup. Also, I know that the jumpers are set correctly for 166. What could be making my PC run so slowely??
