My comp is really weird. I have installed 1GB of ram, but whenever i restart my comp, when it loads into window XP, i slows down alot. it seems like its trying to load something but nothing comes out. We i click "my computer", it shows a flashlight searching for the files. finally after like 1 min, its back to its "expected speed" why is this happening? i tried to delete all those startup programs but its not working. And I found out that when my window is loading, in windows work manager it says that system Idle Process is taking up 99% of cpu? why is this? I don't think theres a problem with my ram but rather my window, cause i just installed a new motherboard so i have to reinstall my windows, but my old system didn't have this kind of problem. This is really weird. Thanks for helping me out here!

My comp spec:

Gigabyte Nforce 2 7N400-L
Athlon xp 1700
1 GB of DDR 400 ram (dual channel)
80 GB (40GB *2)
Geforce 3 ti200
