There seems to be a problem with my computer in that whenever I leave it alone for too long and it goes into power saving sleep mode, computer is "off" but simply pushing my mouse forward activates it, instead of turning off like it is supposed to, the computer will stay on and ALL of the fans will spin at their maximum RPM. This includes my video card and processor fans. This only happens about half the time it goes to sleep mode. The only way for me to fix it is to turn off the power switch at the back of the PSU and allowing the residual energy bleed off. Turning the switch back on too quickly causes the problem to happen agian. Holding down the power button doesn't work.
Hardware is an Asus sabertooth 990fx with an AMD Phenom 1190t. Two Radeon 6890 video cards, 16gbs of Gskill Ripjaws memory, 2 Seagate 1TB Drives, 2 WDC 5000aaks 500gb Hard drives, two hitachi 250gb, and a 250gb OCZ Vertex 3 SSD. All HDDs were supposed to be Western Digital, but Newegg didn't have them or whatever and sent me equivalent HDDs. My PSU is a corsair 1kw.
I am running Windows 7 ult 64bit if thats helps any.
I have tried updating my bios, as well as disabling my raid. I have also noticed that when I turn off my computer, the fans will spin at max RPM for a split second before turning off.
