Computer wont go to sleep!

Hey Tom's Hardware.

I just recently started having a problem with my computer going into sleep mode. The monitor goes to sleep and then my computer tries to sleep but immediately turns back on. Not only can I not put my computer to sleep but I also feel that this turning off and immediately back on cannot be good for my computer. I disabled the mouse from waking from sleep as well as the network interface and it still does the same exact thing. I was wondering if it could be my fans and whether or not I have to turn on or off the Q-fan control? Also, I did reload the default to my bios but I did change the DRAM voltage from AUTO to 1.6V. In addition, I have reloaded my video card drivers recently as well. Could either of these be the problem as well? Any help would be appreciated. My specs are listed below:

i7 930
asus p6t
msi cyclone/oc gtx 460 1gb
3 x 2gb corsair xms3 1600 C9 ram
Antec Earthwatts 750W


Thanks for your help everyone.

  1. Open up the command prompt and from there type in this: powercfg energy

    Don't do anything on your computer while it does the tracing and a .html report will be generated under C:\Users\%username%\energy-report.html

    When that report generates, open it and take a look at what it mentions. If you're not sure, you can always post the information here.

    Hope that helps.

    If you could post the script, that would be helpful.

    Also, try removing all your USB devices from your computer and leaving your computer to see if that sleeps properly as well and see what happens....

    If anyone can spot what the potential problem is, that would be great because I'm lost.

    Thanks
  5. I build my own PC and had the same issue, my other PC I build worked fine. The only changes I had were the mother board, the SSD PCIx4 drive and the liquid cooler. Since the problem seem to be with a USB port the only thing I could think of was the liquid cooler (H80i). Recently corsair came out with an update to there firmware, so I updated the cooler firmware, (corsair link and cooler firmware kind of go hand in hand), I haven't had any problem with my PC going to sleep. I guess corsair must have been aware of this issue to correct it.
