Hi. I am hoping to get some help troubleshooting a weird issue I am having. I have never seen any computer do this before. The computer was running like normal all day and it was just sitting in the office running but wasn't being used by anybody. I turned to look at it and the screen was blue and flickering. I force shut down the computer, rebooted and it displayed the Apple logo like it's going to boot but then it displays this weird corrupt looking screen. We dusted out the computer, we reseated the drives, we pulled out ram sticks and this problem keeps happening. Booting into safemode detects a problem but the computer seems to lock up while searching for a fix. I want to suspect that the video card is bad but would it still show the apple logo if that were the case? Anyway, I have attached an image file of the screen. What should I do to troubleshoot this problem?
