so i have had this problem for a while now that either after logging in my computer will freeze the mouse and keyboard will disconnect and then it will restart,the other thing that happens if this doesn't is that it will keep loading up the desktop then when you think its fine after say 2 mins the same will happen i have replaced all most everything in my pc since i needed to upgrade anyway but nothing seems to have fixed it and not only that sometimes after the crash the ethernet port will go into sleep mode and i will have to reset the motherboard by removing the ram for a little while seeing as i changed most of my hardware i was hoping that would fix it i also checked that my ram had the correct timings and everything, i even backdated my bios to the original version and that made no difference either so im guessing it must be software related..any ideas ? if you want specs just look on my profile and so you know i cloned a dying hard drive onto this new one so that i could keep all my settings and stuff not sure if that could have been the issue or what
