New graphic card -> Stuck at start up

[ALPH4]

I just finished upgrading my g-card from a nVidia 9800 GT to a Radeon HD 5770, now when i turn on my comp, it gets stuck at the windows start up screen.

I tried putting back in my old g-card and it starts up fine, I also used driver sweeper and uninstalled my nvidia drivers but still no luck. I also cleared my CMOS, still no luck. I'm out of ideas!!

HELP!!

Well, after about 20 mins of sitting at the boot screen my computer finally boots up

Why is it taking so long to boot? I should also include that when I had my nvidia 9800 GT it took about 7 mins to boot up which i still havn't gotten around to fixing.

Hi ALPH4....


enter ''safe mode'', run ''driver sweeper'' (for old Nvidia drivers) & reboot.

ive just made the jump from Nvidia to ATI & this happened to me, i found out VERY fast that ATI H/W is VERY finicky.

are you plugged into the correct DVI port..??, all PCIE connections are present..??

what PSU do you have..??

i wouldn't worry too much, your able to reach the BIOS....thats 80% of the battle won.

EDIT: i see your at windows now, its getting there....lol
