Recently my PC has had a persistent issue with hanging under load, and frequent restarting while idle. The logs show this happening several times a day while idle up to once per hour. When I put a load on it, frequently it will run fine for a period then just hang for no apparent reason. When it hangs it the lights on my keyboard and mouse shut off, leading me to a mobo issue but I am not sure. Any help is appreciated.
