Thanks what is process of elimination? The PC restarts more often when i put the ram in slot one but the same also happens when i put it in second one but less often
I would put the memory in the slots recommended by your motherboard to rule out any error. It is likelier its the Mobo that's the issue as constant power shorts can blow circuits easily, and it your reboots may be a result of a blown or faulty circuit caused by your faulty PSU that may have shorted it. If you are to replace something I would start with the motherboard as the Ram is less likely to cause system error out of nowhere. Ram sticks are usually good or bad and do not normally change unless they are shorted.
