Computer starts up after shutting down

Check for WAKE ON features in the BIOS it may be set to WAKE ON mouse or keyboard..

also, refer to your motherboard manual to make sure you have the power switch in the correct place on the Motherboard..

mouse and keyboard wake is Disabled
i checked the power switch and it is correctly place
whenever i try to shutdown, it still does it, i can never shutdown without turning off the AC on power supply...
can ANYONE help?? THANKSSS  

Run Folding@Home on it. Then you have a good reason to leave it on, you will be contributing to finding cures for diseases like alshaimers and cancer. Read about it from the links in my sig.

Congratulations, you totally solved the problem. We should throw you a parade. >>

OP, what OS are you running? Also, when it shuts down, do all the fans stop and lights turn off, then it turns back on, or is everything still running when it boots back up?

Maybe a defective power switch. Try using the tip of a screwdriver or a jumper momentarily.

yeah when it shuts down, everything completely turns off, and then the computer turns on again after like 1 or 2 seconds



its not the powerswitch, because i took it off when shutting down and after the system competely shuts down, it still boot up after 2-3 seconds again without the power switch connected


THIS IS SO PROBLEMATIC, ANYONE HELP PLEASE  

nvm, i solved it, the mobo is gay

i have the same problem with my computer. it shuts down the fans are all off the led lights are off. 2 seconds later it turns on by itself. i've checked all the bios settings and power management settings nothing is set to cause my computer to turn on or wake up. i've scanned for viruses. all clean.

PLEASE, tell me how you solved it! It won't help anyone just stating the fact that you solved it... what was wrong? what did you do to fix it?

noone?   please help

well ima kid the age of 16 and i have this problem too and i am sure what is cuasing it

here is the detail i had a 6200 nvidia card in i uninstalled it and replaced it with a nvidia 8400 gs wich in turn is the same series as the afore mentioned 8800gt it has to do with a fualty new hardware installation that f's it up cuase all i replaced was the vid card and it started to do it and hazzel not sure what your problem is if you instaled a new hardware device than it coudl be your fualty hardware install

Yeah, I had a lot of new hardware installed, that narrows it down a bit I guess. My problem is not consistent though, sometimes it happen, sometimes not. So what do I do to solve it? Reinstall the gfx crad? In my case that means plugging it out & in again... I've done that several times, but might as well give it another try.

(DrugD3@l3r - do you think your age has anything to do with the problem?   )

I was having this same problem after I flashed the bios to F6. I had all Wake On options disabled except for Wake On Ring. Once I disabled that, it shut off and stayed off. Hope this works for you.
