Question about ATI RADEON HD 4850,, PCI Express Video Card
I installed a diamond ati radeon hd 4850. downloaded all the drivers, computer see's it. i have a 19' monitor so my res is set to that and my colors are at 32 bit. i can load in safe mode but the screen has lines in it, and if i load in normal i can barely see anything, my colors are all jacked and there's lines all over. horizontal not vertical. i adjusted my DPI in bios to 1024 but that did nothing. please help. i'm a mechanic not a computer guy.
I have the same card, do you have the proper PSU installed?
I'm thinking you may not have improper wattage for that card.
You'll need a 450W or higher for the card to work properly.
Unplug your computer and hit the power button to get rid of the juice.
Open the left panel and look at the power supply. It will show the wattage.
If it's 450W or above, post a comment and I will help you further.
It could be the directx isn't up to date, but still there shouldn't be lines in it.
Try cleaning the connections and make sure they're tightened first.
Turn off the on-board VGA via the BIOS setup. Restart the computer hit DEL upon startup and look through your settings, turn that feature off. As I don't know your motherboard, I can't tell you where to look in your BIOS.
Here are the specs for your card as well, make sure they match your computer.
