I am having some strange artifact issues on the screen of my 27" Late 09 iMac
Specs....
i7 2.8HGz
8gb ram
ATI Radeon HD 4850 512 MB
OSX Mavericks OS X 10.9.4
I have never once had an issue with my iMac in all the years of owning it until today.
I am running the newest OSX Mavericks that i updated to the week it was released ( did a few clean installs )
I get artifacts appearing all over my screen, anywhere from colored lines, to black boxes, to the mouse pointer disappearing ( though i can still use it, just can't see it )
When i go to open a program like mail, safari, finer, etc. The window appears as a black box, you cannot see anything but a black box but you can still click on stuff and the iMac works fine, So does the selected app your using, Its just visually you cannot see or make out anything because its either all artifacts or a black box.
Some parts of my screen will be fine while others are just all messed up. Its not always the entire screen,
I tried to do a fresh install of Mavericks ( which i have on my thumb drive ) and it did its thing and when it was finished and it came time for me to input my country, wireless password, etc. the boxes that displayed the info were all crazy looking or just totally missing to where i could not even see the continue button to finish.
This has been happening all day, The ONLY way i can use my iMac without any visual issues is if i am working in SAFE MODE ( which i am in now )
I am out of warranty and have no clue what the problem is? I never once had an issue with my iMac, I don't game, I don't abuse it, I don't install any crazy programs.. It just all of a sudden started doing this and the only way to use my iMac is in safe mode. I don't a clean install, reset PRAM, unplugged my iMac from the wall for 15 mins, i disconnected every single piece of hardware connected to USB ports and still.
Would anyone have a clue what the issue may be? My only thinking is that the video/graphics card it going or about dead (My iMac has the ATI Radeon HD 4850 512 MB graphics ) I don't game so never had a need for high end cards.
I am guessing (though could be wrong) that it isn't a software issue and more a hardware issue.
Any advice from anyone? My iMac is out of warranty and i really don't have the funds to fork over to have Apple store look at it.
Thanks
