I got a gpu from a friend, uninstalled the previous integrated graphics card's drivers, and then shut off, installed the gpu, an ati radeon 3450. started up and got bsod.

after a few trial and errors I got it running, and it auto installs the driver, and then I get vertical lines on screen, no image, just solid color with lines.

system restored, which most likely reinstalled the nvidia drivers, and still had the new card in, it still started up and will run for a few seconds, but then i get vertical lines again.

I thought that it might be over heating, so I opened the case up and turned my fan to it. which didnt help.

now I stupidly tried to do a factory restore on the computer, so that none of the drivers would be installed, but now the screen is back to vertical lines, so im waiting for the process to finish and hope for the best. need help please
or have I just royally screwed myself.

 

The card's physically damaged/dying. You will not be able to use it properly.

thanks for the help you guys. I probably messed up in the first place, as I have no exp in installing gpu's. cus I didnt uninstall the intigrated's drivers first, and all.
but going into safe mode with the gpu out, I uninstalled the nvidia graphics drivers and then shut down. installed the gpu again, safe mode, then uninstalled the ati drivers that windows had installed. restarted, it started like normal, and then windows attempted to install the drivers for the ati again. then it prompted a restart, I said later, and went to download and install the drivers from ati's site, it was the top driver for the radeon 3k,4k,5k series's and before I could even start that installer, it vertical lined me. so i restarted in safe mode, and attempted to install, but the installers said that it couldn't detect the card type.

edit-
ok so I did a restore, have everything back to before the gpu was installed. then I installed the gpu, it was low 8bit colors, and auto installed its drivers. i attempted to install the catylist drivers, screen goes black. restart, bsod. so i go to bios, set the gpu to onboard, with the ati card still in. pc starts up fine. device manager shows the ati radeon card in it, so I instal the catylist ati drivers. it installs fine, no errors. now attempting to see if the card will work or not. any reason why it would do this besides it being faulty> my psu is only 300 watts, so i thought that it might not be getting enough power..

edit 2-
this gpu works fine in safe mode. so something must be wrong. should I upload my bsod dump?

edit-3 ok, 15 min in and it does this

re-install windows, assume the screen displays fine on boot

 

there's defiantly an issue with the graphics card then

i would get a new card, its probably the reason your friend gave it to you

 

trade back then, clearly he gave you a bum card
any card is better than a broken one

 

Again I have to ask, what iGPU were you previously using? Is there really a need to move on to 3450 or 5450 low end/non-gaming GPU?

 

anything is better than this. its a GeForce 9100. in a hp pavilion a4316f. I know its not meant for gaming, but its better than nothing.

well its not my money lol, so if it is defective, all I can do is just send it back and hope for a better replacement.

 

The first one.

 

ok, thanks. dont want to screw up lol.
