I had an i5-2300, and I upgraded it to i5-2500. I already had a great working windows 7 with the i5-2300, but when I installed the i5-2500, my computer started to crowl like a snail, raising the upload time from few seconds, to 5 minutes, and more. it starts when it get's stuck at the windows 7 introduction black with colorful fireballs window, there it get's stuck for 5 minutes. another thing that I've noticed is that the red lamp indicating that 'the computer is thinking' is consistantly on, through out all the time the computer is working. so I've tried to format the hard drive, and nothing changed. can anyone help?
