| | I have run the virus/malware checks and they've come up with a few things detected, however, they wre just a few programs and were perfectly safe. Then I proceeded to do the ram check, it came back with 13 errors, I've attatched a picture of it. I have not yet run the GPU and CPU checks, should I or should I just change the ram stick? Thankyou very much. |
