So lately I got a new CPU (Phenom x4 955) and an Asus 6850 video card and for a while I thought that one of those was failing because I would get a blue screen a couple of minutes into a gaming session. But then I read a small artlicle on PSU failure and I think that it might be the PSU
Now according to this article signs for PSU failing include:
*Nothing happens when the computer power button is pressed. Sometimes a light may flash or flash continuously in the front of the computer or on the back of the power supply.
* Computer turns on for a while, but when games or other applications are using the computer steadily, it will turn off or I get a blue screen.
This are 2 things that happen to my computer a lot lately specially the blue screen thing while gaming. Also they mention how lightning can be causing this and I am on rainy season here in Florida and every time there is lightning the computer shuts down and then "Nothing happens when the computer power button is pressed". So I'm 90% convince that is the PSU but to enforce my thinking I would like you guys to give your opinion. I know some of you know more about computers than I do.
First off what is the PSU type / brand that you are having.
The problem you are describing can be alot more then just your PSU...
-Wrong bios settings
Apart from PSU type / brand also state the rest of your system (if possible) in detail.
ok, last three things...
Can you tell us the following:
-what is the error returned by the BSOD?
-what are the temp idle / load of the CPU /GPU?
Did you do a stress test on the system to see how the system reacts under full load (non-gaming).
The error returned by the BSOD is the error message in the blue screen itselfe.
It can be that this is only showed for one second due to settings you can change that in the system properties under startup and recovery setting, here set automatically restart to off.
Furthermore with your last problem description i found something on the amd forums: http://forums.amd.com/forum/messageview.cfm?catid=22&th...
This should direct to a voltage problem, can you double check the set voltages in your bios and see if they are not set too low / high ?
