When doing install do you also install Anti Virus software ? if yes - which ?... another thing is that my HD:s are doing something all the time win 7 is running...

When scanning HDD light stays on until it finishes upto an hour and PC is pretty much unusable. (this is with Endpoint and on XP Pro)
try install without any AV
