CPU 100%

i would like to know why my explorer.exe is using 79% of my CPU
i went to the the resource monitor. and its the explorer that is eating my
cpu.
and also when i turn my computer on and login in. i just get a black screen
and a white cursor it takes about 4mins for my desktop to load. this has
only been happening recently.
is it anything to do with the performance updates????

its Vista Home premium
2.8Ghz
1024MB Ram
