For a week or so ive been running my old amd processor cos i thought id burnt my other one out. But now im not so sure because there are no burn marks on the chip. I thought it had burnt because there are small black lines on the top of the cpu, where it says L1, L2, L3 etc. Ive just looked at some amd cpu images on google and these marks are on the cpu's so im guessing they come like that. If i decide to test the cpu what will happen if it is damaged? could it damage the rest of the hardware or just not boot? Thanks.
