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:
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.
Here's some more info on my computer if it helps:
General Spec Brand
Gamer EXTREME 923i Processor
Intel Core i5-2320 3.0GHz 64 bit Quad-Core Processor Cache Per Processor
6MB L3 Cache Memory
8GB Hard Drive 1TB Optical Drive 1 24X DL DVD+/-RW Drive Graphics AMD Radeon HD 6770 1GB Audio 8 Channels Power Supply 600W Operating System Windows 7 Home Premium 64-Bit
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?
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?
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.
