Hi, first time writing here. I've got a problem with my 470 which I bought a year ago - while playing DiRT3 I noticed the temps we're getting upto 110 (70% fanspeed), so I decided to take a look inside. It looked quite dusty so I took the cover off and did a quick round with a vacuum cleaner over it (I didn't touch anything), when the majority of the dust was gone I put the cover back on and connected it again to the mobo (P8P67). I started up the PC, and all was running fine, except the monitor was not displaying anything, so I reconnected everything a few times but it stayed the same. Some articles I found on Google suggested that the cables aren't connected properly or that there are some errors with the GPU, but I'm very sure everything is connected properly. Any suggestions?
