I3 330 processor

previous 250 GB HDD
Windows 7 Home Premium 64 bit
Previous WEI of 3.7
I just installed a Samsung 830 128 GB SSD and did a fresh install of Windows 7 64bit. I used Double Driver as recommended to transfer drivers, loaded Windows 7 on USB flash drive using Microsoft USb software.
The upgrade went smooth. Just as it was described online in the forums here. I plugged in the Samsung SSD, plugged in the bootable USB for Windows 7, installed fine, set up, reloaded the double driver files.
Computer started running hot and the fan was running nonstop almost. I downloaded the samsung magician management software, it corrected a number of things in BIOS, this helped with the fan and heat.
But the computer overall is not much different than before the upgrade, even slower waking up from sleep mode than the HDD.
