I recently installed an Intel Pentium Core 2 duo 2.8 GHz processor. (replaced IP 4)
My system is now taking twice as long to startup compared to previous Intel Pentium 4 2.2 Ghz. processor. (From start to explorer opening takes 4.3 min. now. Used to be 2.3 min)
I have cleaned registry ( Tuneup Util.), Defragged, virus scanned (AVG, ETrust), even tried to repair with Win install.isk. ( No go, PC version is newer than the installation disk).
I have a NVIDIA GE force 7100 vidoe card of which I updated the driver.
ROM = 200 GB, ram = 2 GB, Motherboard = ConRoe 1333-d667
