Shut Down = power? ***!

post #1 of 4
Thread Starter 
Not sure if this is the correct forum to be placed...so here goes.

My sig rig is experiencing some odd behavior on occasion (does not happen too often) during shut down. The system will shut down windows normally and go to a black screen on the monitor but my computer will still be running, as in power is still being supplied and my fans are still spinning. I have two optical drives, one SATA, one IDE. The IDE one will open and close when this shut down hang occurs. However, the SATA drive will not open and close when this problem occurs.

I started to notice this problem after attempting to reach my max OC, which was about 3.4ghz. After reaching that max I went back down to stock speeds because it just wasn't stable enough.

Any ideas as to what could be causing the shut down power hangs? I'm thinking it could be.....PSU, motherboard, or maybe processor.......any help would be greatly appreciated.

My musings:

Sounds like a motherboard issue... My mobo issues are normally refusing to post though...

Power Supply: Can cause instability- And possibly damage things... 0.0 In any case try a new PSU, from a better company (PC Power and cooling anyone? Or corsair- I like some of their stuff... *Shurg*) If its a bad PSU that removes any possibility of that being the issue, and I have NEVER heard of bad hardware damaging a PSU... just the other way around.

Then I would try a motherboard... After that? No idea personally

That's just my opinion.... Or 1/10'th cent. Good luck figuring out the issue!

I had the exact same problem on my old comp, after a few months of trying to figure it out it was the PSU, you need to replace it asap, my temporary solution was to shut down the comp, wait 10secs, then pull the plug, no harm came to it so i guess it was ok, but im nearly certain its the PSU

Your PSU is going bad and probably just sending out a bad signal. It would be wise to hurry and replace it because you don't want it to send out that one signal that will fry everything.
