So i randomly started have a huge lag problem in my Computer so i clean everything and updated all my drivers. This didnt help, and now when i boot up any program the PC randomly crashes. So i go to best buy tell them whats happening and they told me to try a new power supply, i did and it did the same thing when i started a program. I RMA my motherboard (because thats the only issue i can think of since the computer is only a year old) and get it back and the restarting problem is gone but im still getting extremely bad performance in all aspects of using the computer. I tried using a different graphics card and that didnt help either. Any suggestions or help would be appreciated!
