Slow Startup

see if my words helps...skip the steps that u already tried.
1. check the start-up items. Run the command of "msconfig" , check the "start up" page(i am not sure of the precise name of this page,coz.i am using chinese version of windows). diable ALL the items listed. save the setting and restart.
2. check the free space of each partition of harddisk. make sure that each partition has a free space of more than 1 gb( higher ,better).
3. check the list of installed programs, through the control panel. uninstall those seldom used
4. it might be unkown comflict of softwares. keep your system as clean as possible. for example, you can disable your antivirus, then restart to see if it is faster
5. it might be fragments. defrag all partitions.
6. manage the services of your system. right click "my computer",click "manage(G)", in the window below, the third level-1 menu is "service and applications". disable unecessary auto startup services.
7. up to repend~~

 

Slow Startup

Does anybody know why I am having really slow system startups? I don't have extra startup programs than I use to have. The only thing that I think it could be is my antivirus program. I use AVG now since I reformated 2 days ago..and every since then, I have a really slow startup..I don't know if that is the reason..Does anybody have any suggestions, on how to speed my startup? I use to be able to be on my desktop screen in like 35-40 seconds at most. And now it is way over a minute. Any help would be gr8.
