Had my pc for over a year now but this last week i have been having a problem getting it to turn on. when i hit the power button it comes on for 1-2 seconds and immediately turns back off again, after a few tries it does boot up and says "Please reset CPU or memory frequency in CMOS setup" and the choice F1 to continue of DEL to enter BIOS. pressing F1 it boots up and when its running everything seems to be running like ususual but i have noticed a crackling noise that sounds like it is comming from the PSU im not 100%. I Dont want to use it when i have to keep forcing it to turn on incase i damage the hardware. Any ideas whats causing this problem?
