It might be a server. Servers stay on 24/777 days! That's a crazy amount of time. Electricity bill and risk of fire aside, why do you keep it on like that?
its not a server its my main PC lol.
my servers been up for 68 days atm, running 2003 server and its still very fast for the spec ? running dns and active directory.
i worry a lot about it catching on fire, epsecially when im away from home which I am most of the time.
Now why on earth would your main PC be up for 77 days!?
Have you not rebooted from monthly updates at all?
I find XP SP2 runs flawlessly with no updates applied but there are probably lots of vulnerabilities.
Just a quick note, there are plenty of vulnerabilities that will not be stopped by a firewall as they are piggy backing in on legitimate ports/web traffic. Just thought I'd let you know.
