I'm having some really strange screen issues

Gentlemen (and ladies),

I bought an iBuyPower 923i just a few months ago and I'm already starting to have display issues. If I'm merely browsing the internet or working, everything is fine. However the moment I play a video or game this happens:

Please excuse the background noise in the video; I was printing labels.

If I play a game for longer than 20 minutes the screen will go completely blank (or display vertical lines) and become unresponsive.

Here's my graphics card information:

Someone on another forum had a similar issue and it was recommended that they flash their vbios or update their motherboard chipset drivers. But I have no experience with either so I'm not sure if that's a good idea.

Edit:

Here's some more info on my computer if it helps:

Heat and/or power issues typically cause these problems. What make and model of power supply is installed in your rig? Also, are you measuring your system temperatures (CPU and GPU)? If so, what are your idle and loaded temperatures?

Seems like overheating or something failing perhaps.

Thanks for the response! I don't believe it's an overheating issue. When idle, my fan never really goes over 40% and my GPU temperature is around 40 degrees Celsius (which I think is normal).

When I playing games it hits around 65% for the fan and 55 degrees for the GPU. Is that normal?

What make and model of power supply are you using? iBuypower has been known to install what would be considered "junk" in some systems.

check that you have full power to the card, and that it's seated properly, is your motherboard 24pin or 20 pin power connector?

Sorry for the delayed response. Here's my power supply:

Coonix COPS-600
50-60Hz 600W

I contacted iBuypower and they issued an RMA for my card. However, after reading your responses I'm starting to think the Power Supply may indeed be insufficient.

Is this good enough for a Radeon HD 6770?

I would replace that PSU with a Seasonic or Corsair. I wouldn't trust my rig with that device.....period.

Even a cheap PSU could push a 6770 which under load consumes +/- 110watts.

As it was mentioned above, I would get a higher quality PSU "Coonix just sings cheap to me" rule of thumb is that a PSU is the single most important part of a computer and this should be taken very seriously if you value your machine.

...the Corsair is $39.99 after rebate so it's a win win. Also you did the right thing by having iBUYPOWER RMA. That's what I would've done...

thats fine... 70% on a core is a tops, and GPU is way higher than that.

My guess would be PSU out of experience. PSU - the most overlooked component. BTW be sure you have a good program monitoring temps. Depending where sensors are can affect what they read.

Do it... That's an insanely good deal and they wont last long. I was surprised myself while I was looking for a nice cheap psu for a youngin... I was going to recommend the CX430 but found this 500.
