Black Screen After CPU Upgrade.
Hi, I have a HP laptop dv9740us with a T5450 CPU. with a HP 461069-001 INTE CPU DV6700 DV9700 Series Motherboard
I bought a new CPU (Intel Core 2 Duo T9400 2.53GHz 6MB L2 Cache Socket P 35W) and installed it.
After I booted up my PC, it just stays on with a black screen.
I can hear the fan working and other lights on, but nothing on the screen...
