I am having problem with poster. Poster ask question, i answer then poster ask question again later. Computer not wake up from sleep because power supply is having near death cancer. computer sometimes not load into windows for same reason. Poster has to turn switch off on back of pc often to start again. Power supply is finished. If poster not like answers nobody will reply.

The power supply is running fine . That why I am asking if it is a software problem .
