I had ignored it for the first few days here on Win7, but now it is being real annoying. First off hardware list. Win7-64-enterprise PhenomII 940 4Gb 1066 Muskin MSI K9A2 Platinum His 4890 1g Audigy 1 pci No raid in use No Overclocking Windows is installed on a 120 ide WD on a separate 14gb partition (4gb free currently) with the systemp on the other 100gb part of the same hd. No paging file used on that hd Using AVG 9 free, Various windows tweaks. More if needed The issue is as follows. During first loads of programs I expect to see my hard-drive light go solid for as second and then the program load. But my issue is when doing things like. -expanding a menu -opening a dialogue (in almost any random program) -opening the addons list in FF. -navigating between folders in explorer -Clicking an Auto Download link (no Dialogue) -Saving this edited POST!!!!! -pasting text! Sometimes.. NOT ALL THE TIME but sometimes when I try to do these things (and others) my HD light will go solid for 3-5 seconds and the program will hang(Not the Whole PC) and then when the HD stops the action is completed. The "pasting text" one that just happened is what brings me here. Can anyone explain what would cause this sort of thing? Nothing in my Process explorer has very high I/O reads/writes and I have tried to monitor it several ways while it happens. My CPU doesn't spike either.
