I just built a new computer with an Sr7-8X motherboard and a P4 2.8 Ghz processor. Come to find out, noting appears on the monitor when put on. Everything was checked and the problem is the motherboard becuse one of the pins for the cpu fan doesn't work. the motherboard is totally messed up and i need to return it to the company. All i want to know is if i can somehow check if the cpu still works. I did hear that when a motherboard goes bad the cpu can go bad along with it. The moherboard came with the cpu as a combo that i ordered and i was hoping to know if there is some way to find out if the cpu still works and hasn't gotten mesed up with the motheboard. i wanted to just order a whole new motheboard instad of sending it back and going through al of that trouble.is there some way can test the cpu to see if it wasn't messed up with the motherboard? thank you.
