Problems with BIOS.... causing computer to go to sleep unexpectedly

Okay, so I am having a problem with my mobo getting random bouts of sleepiness.....I will lose my mouse and my keyboard will be useless. Here is what I am running:

1. Gigabyte GA-Z87M-D3H Z87 MOBO, with an I5, Quad Core processor
2. 2x8 GB Corsair Vengeance 1300 RAM
3. EVGA GEForce GTX660, DDR5, 2gb ram
4. 1tb Seagate SSD
5. Ultra Hybrid HS650 Modular PSU
6. Wireless Logitech keyboard and mouse, with unifying receiver.

In an effort to troubleshoot the problem, Ihave run burn-in tests and diagnosed all parts of my computer individually through testing... PSU, MOBO, RAM, HD, and processor all check out fine. I also have all power-saving features disabled, along with screensaver. However, I am still having this problem, which now seems more and more to be a problem with a setting in BIOS, which is causing the computer to "freeze up" randomly.

Actually, to be more specific, it seems that if I leave my computer idle for a few hours, my computer will lock up... the mouse cursor disappears and I have no keyboard functionality..... I can't wake my computer up with "CTRL + ALT + DEL". My USB and other functions seem to be operating normally, and my monitors do not go blank. Eventually, I can wake up my computer by agitating the mouse for 10-15 seconds. or resetting my computer.

I am thinking that something in my BIOS is causing my computer to sleep. Anyone else out there know what might be happening?

Thanks in advance for the advice and help.

  1. Did you check-in in your control panel,power options???
    If not get in there,change the settings or that doesn't help change it by going thru the advance setting...

    Check Your Mouse and Keyboard

    A wireless mouse and keyboard can cause your computer to wake up for no apparent reason, and to not wake up from sleep mode when you press a key or move the mouse. This may also cause your screen saver to not work to. If the computer is using an optical mouse, changes in light can cause the computer to wake.

    Oftentimes the cause of this sort of random hibernation/shutdownis overheating. Most computers are set to hibernate if the internal temperature reaches a certain level. A friend of mine has an Asus laptop, and it tends to run hot. Speedfan is a very popular piece of software which can be used to check the temperature being reported by your computer's internal sensors. You should be able to find a datasheet for your CPU, which will tell you the heat tolerances, and whether it is in fact the heat that is causing it to hibernate.
  3. 1. My Control Panel Settings are set so that my computer's power-saving/sleep settings are disabled.
    2. I cross-check temps with Speedfan, CPU-ID.

    I think I am leaning towards my wireless mouse/keyboard combo, although I never had this problem with my previous setup.

    Thanks for the advice.
