My brother was changing hard drives on one of my older comps that has all my imortant stuff on, any way, now there is no picture. I tried moving my good monitor to that comp and there is still no picture. I moved that monitor down to my new comp, the picture works there. The hard drive is fine, i put it in my new comp and it worked great. I can't try switching video cards becaue that mother bored is too old to take this one.What could be doing this? how can i fix it? I am in big trouble if i don't fix this! The comp is about 8 years old now.
