I am working on upgrading Compaq pro EM series desktop for a co-worker. I was adding a second HDD and 1g RAM. After plugging in the HDD, the computer stopped working. Every time I boot up it takes me to the Compaq splash screen with an option to hit f10 to enter setup, but it doesn't work and the hour glass in the corner is frozen.
I tried removing the new HDD from the computer and booting just using the old one, but now it does the same thing. The computer was working before I added components, but I need the new HDD to work. Any ideas?
