Windows 7: Occasional computer shutdown with computer still running, no signal

Occasional computer shutdown with computer still running, no signal

Good evening,

I have a custom build, amd 8 core 16 gig ram..... Do not know what the problem is. Computer has been running fine for 6+ months. Now the computer occasionally shuts down, but the tower doesn't shut off. It stays on but my monitor says "no signal detected." I have to shut off the tower either via the power supply reset switch or pull the plug. Then when trying to restart both the power light and the hdd light are solid. I mess with the power again, and then it will start again. I have not found a consistent method for getting it to shut down. Sometimes its in the middle of an MMO. Sometimes when I log off the MMO. Sometimes while its just sitting and nothing is happening.

Please help with suggestions.

Thank you

Check the data plug on the hard drive. Will do that if not 100% connected.

Try disconnecting all the secondary & optical drives. One may be malfunctioning or it sounds like there may be an intermittent short somewhere. Perhaps an issue with the psu. Limited sys spec details, this custom build have built in video on the board or pci card? If it's a card make sure it's slotted firm & properly, if it's a card check it's pin power if it has a plug for it. If both try the built in video for a test then boot up without the card to help troubleshoot.

Hello Mydknyght,

Do you have a powerful enough PSU to handle the load of your system?

You might also check to see if the graphics card may be over heating and shutting down, the graphics card is seated fully and securely to the motherboard's PCI-E slot, and that any separate 6-pin or 8-pin power connections to the graphics cards are fully and securely connected at both ends.
