I don't know for sure if this is the right place to ask this, but it's the best I could do.
I've been having some strange issues lately with my computer. On cold start-up after sitting overnight, the computer will not turn on. It will boot to the BIOS, but it never recognizes the USB because the keyboard and mouse lights will not turn on and it hangs. It does not matter if I unplug all USB peripherals, it will still hang. After multiple attempts to boot, the lights on the keyboard and mouse will flash and it will boot. About 1/4 of the time, I have to reset BIOS options because it loads an older BIOS. This does not happen with a reboot or shutdown and restart if the computer has been used and is warm.
Also, while in Windows 7, my GTX 260s idle temp is normally around 40-45 C. But after being logged in for a period of a couple hours or more, idle temps hit and stay above 70 C. If I reboot or log out and back in, idle temps go back down to the normal temps. Case ventilation is good, and I've used compressed air to clean out the card's heatsink.
My guess is either issues with the motherboard or the power supply. Does anyone have other ideas? Any help is appreciated.
