Ok guys, I'm at the end of my rope. I have built a system and have had it running fine for a year now. I have a msi 570-g54 motherboard with a gigabyte hd 6850 gpu and a amd quadcore black edition cpu. For some reason around a hour after the pc has been on the monitor goes black says I lost connection and the sound cuts out. The tower and all the fans run fine. I replaced the power supply,check all the wires, and re-seated the gpu. I have no idea whats going on. All the temps seem normal leading up to the shut off..
Do you have your rig set to sleep or hybernate after not touching the keyboard or mouse? Every computer I have ever owned always does something I have never ask it to do. Has anybody else been on it?
Why we think it is a heat problem is The system has been on for an hour and a half then the monitor goes black and shows disconnected. That is a normal sign or over heating. Does this happen everytime you turn on your rig?
