My monitor shuts off during games, but the computer stays on

Specs: Windows 7, Intel Core 2.67GHz / 12 GB Ram
Hey!

I bought this computer 1 year ago, It's really expensive and has really good components!
This computer was working fine for some months, the my problem started.

When I'am playing games, my monitor randomly shuts off, the audio aswell.. however the computer stays on! Well, the monitor is losing signal, so all I will have to do is restarting the computer again, but it will shut itself off again when starting a game.

This can happen when I've played for like 1 hour, 30min or even just a couple of minutes, I haven't experienced this happening when watching movies or such.

I've tried to install new drivers, I have also tried to remove dust from inside of the computer. Another thing I have tried is to lower graphics settnings, but again this shouldn't be a problem, my computer should easily be able to handle max graphics. + It can't be an overheating problem, cause my temps are below 60*C even when gaming.

I have a few things that might be the problem, but still don't know how to solve it:
- Failing PSU
- Failing GPU
- Dust


PC SPECS:
- XFX Radeon HD 6970
- Intel Core i7 quad processor i7-920
- Corsair Powersupply ATX, CMPSU-1000HXEU

Im running Windows 7 Home Premium

I so desperate for help, so please!

Thank you for every answer!!

Download and install HWMonitor to view temperatures and voltages in real time. Get it from the link below.

Hi, I already have this program. Do you want me to post you the results?

Your temperatures appear to be OK. However, your 3.3v, 5v, +12v are all out of spec.

Boot into the BIOS and look at them in there. All values should be within +-5% of the stated values. For example, 3.3v x .95 = 3.135V. Your readings are much lower than that. Could be a glitch on the sensor settings.

How do you know the computer stays on but monitor goes off?

Do you have the screws tightened down on the connector to the GPU?

Thank you for your reply!

To be honest I'm not really professional at computers. But I can try to change the settings that should be changed.

The 3.3V is the voltages right? Where do I find this in the BIOS, and what values do you want me to type in?

My monitor shuts off, (blacks out) I do easily see that the LED is not on, and the green/blue button on the monitor turns orange (on, but no signal).
However the computer shuts off. I got red LED lights inside of my computer that stays on aswell as the fans also stays on.

How can I figure the tightned screws thingy?

With the errant voltage it probably is a power supply that is going.
That voltage is not something that can be changed, it is what your power supply is supplying to the system. You just need to check the reported voltages in the BIOS to verify that they are not acceptable.
Post your detailed hardware specs, especially your power supply Make, Model Number, Wattage, and (important) the Amperage ratings for each voltage (3.3V, 5V, & 12V (all12V, if more than one) from the sticker on the power supply). This will help us determine the probability that the power supply is underpowered, or going bad (happens often with cheaply made models, less often with better ones).

You have to be a little bit crazy to keep you from going insane.

Fingers

Hanseens has a 1000 watt Corsair PSU with 80A @12v. Not a cheapie. See the original post. Still could be going bad though.

Sorry, I apparently did not scroll down enough and missed that, though I thought I went back to see if the PS was listed.

Well, I might send it to a repairer, which might cost a bit.. I can't enter my BIOS with my new keyboard, with the NUMLOCK on at the boot up for some reason.

My PSU isn't actually a cheapie, but of course, yes it might have f* up aswell!
I have heard that before, that the reason for this problem might be a failing psu.

Do you think I will have to change my PSU?

The only way to be certain about those voltages (and hence the PSU) is to physically check them with a multi-meter. If that's not your scene then taking it for repair is the only option.

Numlock is usually a BIOS setting and the fact that you cannot get in there to check does make one suspect that the voltages really are as given and you need a new PSU. Fitting a PSU is not so difficult but again if you've not done it before you might prefer to get someone with experience to do so.

Always pop back and let us know the outcome - thanks

If you can't enter the BIOS with your present keyboard then try using a PS/2 type keyboard.
