I need advice with the following: Is there a software that would let me know what Vista does at a specific time while loading or shortly after? The reason for asking: ever since I built my computer (about year and a half ago) and clean installed Vista Home Premium, shortly after I log in and my desktop shows, the OS slows down for about 15-20 seconds or so doing something. Not a big issue, I just want to know what is going on. A couple of wild guesses here: - antivirus loading and scanning memory; - Vista checks the network and what's present; and - some obscure old driver is loading and looking for some hardware that I removed. Just to give better idea about he system that I'm running: Gigabyte P35 motherboard; Intel Core2Duo E8400 processor; Two WD hard drives (500 GB and 1TB); nVidia 8800GTS 512 MB; OCZ Reaper DDR2-1066 4 GB of RAM; Vista Home Premium 32 bit. No overclocking. Attached peripherals: Epson photo printer, Epson photo scanner; network printer. Also on the network: two desktops and a Linux file server. Printers directly attached to the computer and the Linux file server should be of no consequence - issue started before those were introduced. Malware should not be an issue - I'm paranoid about security and the issue started pretty much immediately after an OS install.
