I got a laptop, it a solo 2150 version 1.5. It has a 600mhz mpga2 on it. When I upgrade it to a 800mhz, everything power up except the screen and it does not boot. I put the 600mhz back in and it boot. Then try with a 700mhz and it does the same thing as the 800mhz. I checked gateway and it same it support the 700mhz. Any suggestion will be helpful. Help!!
