hi there everyone i have a computer that i have built all infomation is below.

The problem i am having is that my comp is now running very slow when it turn on it take about 15 min to boot up. prior 15s so as you can see it is a very big change in load time. i also cannot get into my bios because for some reason the usb does not work (making me think that it might be a motherboard problem). i also tryed to put a system disk in there to just start new but the cd/dvd drives i had also did not work (they work when the comp is all booted up). when the comp does get running i cannot get online and my fire wall will not turn on

(the window reads "Windows Firewall cannot run because the Windows Firewall/Internet Connection Sharing (ICS) server is not running. To use Windows Firewall, you must start the Windows Firewall/ISC service. If you configure excaptions for applications or services that were running before you started Windows Firewall, you might have to restart your computer so that these applications and services run properly. Do you want to start thw Windows Firewall/ICS server")

and when i click ok it read

("Windows cannot start the Windows Firewall/Internet Connection Sharing (ICS) service.")

I have checked to see if all of this has to do with a virus but from what i found there was nothing (i used clamwin)
so if any of you have anything that could help me please do.

Thankyou
