Hi my pc keeps crashing and going to a black screen then the dram light come on the MB , then after a-few minutes it boots back up then happens all over again. at first i thought it as faulty ram so i tried running it with with just one stick then the other stick and i had the same problem. then i tried updating all the bios of the MB same problem. i have had the pc for 7 months running fine till the cpu broke about a week ago witch i have replaced and it ran fine for the first few days till this started happening any help or ideas would be much appreciated. thanks
