Alan If you see these spikes and nothing is disrupted in PSDR, there really isn't a problem is there? Do you have any symptoms of a problem while running the radio?
If you are having problems, I would not invest any more in that motherboard/cpu/memory. AMD Athlon X2 250 - $65, ASUS M2A74 microATX motherboard - $60, 2GB of G. Skill DDR2-1066 memory - $53. For $178 you can have a retooled system that will really work well.
