PSU issue ? (looks like dead PC)

post #1 of 5
Thread Starter 
Hey there,

following this thread
http://www.overclock.net/t/1451024/new-pc-freeze-while-playing-3d-games
i solved the problem by adding some voltage (0.1v) on CPU and PCI-E card from i remember) and no more problems until yesterday.


i have now a bigger issue.

yesterday, my PC froze 2 minutes after game loaded.

I tried to reboot (case reset button), i heard some fan, but nothing. No reboot and black screen, PC still frozen

Then i tried to power off (case button), nothing ; i couldn't power off the PC.

Then i switched ON/OFF on my PSU switch. Black screen; and PC shut down.

Then switch ON, i push power button -> nothing. No fan sound. Nothing. seems like nothing electrical come.

I don't know if my PSU died, my CPU died, or my MB died, or all 3.

My rig is the one on my signature.

For the record, my PSU fan stopped to work about 6 months ago, but i didn't had any issue about that.

Any help would be greatly appreciated. Thanks

It might have died but try this trick first

Unplug your power cord from your PSU then press the case power button lots of time this will remove any and all power that might be stuck in your system

If that does not work then PSU might very well be kaput

First thing I would do would be to test the PSU... make sure it is outputting the voltages it should. If you lost a fan on it... it may have overheated, once you started putting a load back on it (gaming).

Do you know how to use a multi-tester? If so, then carefully test the PSU per the voltages and diagrams here: http://en.wikipedia.org/wiki/ATX

Also check the fuse in the PSU.. but be VERY CAREFUL... there can be some serious juice in those caps in the PSU. It can hurt you.

If everything looks good there... then you need to test the PSU under load, which means putting it back in the PC. I suspect the PSU more than anything else, based on your comment about the fan.

Do you have the system on a UPS?

Shilka (who posted above) is very knowledgeable about PSU's, and can probably suggest more things than I can.

Again... unless you are very comfortable with it, don't open up the PSU case... and that will be needed to check the fuse. If you do, please be very careful!

I have tried your trick, but unfortunately it didn't work :-/

I din't have a multi tester, and i din't have enough electronic skills for the fuse...

I have a rescue PC which have an OEM 480w PSU, should i try to switch PSU in order to see if something work ?
Problem is that since i have a CPU Noctua cooler I dont have much room to work in the case and some cable seem hard to plug/unplug.

Could it be something else than PSU that could cause something like this ? (i mean complete shutdown, no pc reaction, i have never experienced a broken MB or cooked CPU)

I plan to buy another PSU, which ones could fit my situation please ?
Seasonic G 550w is enough for my rig ?

Thanks
