I've scoured the forums and found the tutorial here: https://www.sysnative.com/forums/windows-7-|-windows-vista-tutorials/5721-how-to-diagnose-and-fix-high-dpc-latency-issues-with-wpa-windows-windows-vista-7-8-a.html I use a 32-bit vista system, so I downloaded Latencymon 6.0 Free in order to identify what's causing the DPC issues, but to my dismay, I get an "Access violation at address 005FA1E6 in module "latmon.exe. Read of address 0000039c". So far, based on my observations: - Moving my linksys wmp600n card from one PCI slot to another does not work - updating the drivers do not work - updating the chipset did not do anything to fix it. - REMOVING the card stops the all DPC latency issues, however, I the need internet. - Adding in a new wireless adapter card still causes issues. I've been stumped on this one, all thanks to that Latencymon access violation that prevents me from seeing the problem, and I really need this computer to work again. Please, help me solve this!
