I recently installed Windows 7 Ultimate on my machine and its been nothing but a painful experience. My system is shooting up 100% usage with in half hour of usage. Laptop is heating up like anything (is this the cause?). As soon as I open FF or Chrome, the usage is shooting up for 100%. Today I tried to copy some 5 gig of data from External HDD to my laptop and as I guessed, with in 15 mins, usage was 100%. Note: This system has no other s/w installed yet, other than Office 2010 and Kapersky Anti Virus 2011. System Config:
Intel Core2 Duo CPU T8100 @ 2.10Ghz RAM: 4Gb System Type: 64 Bit.
Attached are the snapshots of performance:
