i'm having a big problem with my computer right now
it suddenly turns off and when i try to turn it on again
the computer turns off again after a second. and if i let
it rest for an hour or more i can use it again. and this week
my problem got bigger when my computer won't boot at all
anymore when i wake up. and i tried to trouble shoot.
if i remove the video card which is xfx hd 5770 my computer
are starting to boot. but the sudden turn off. of my computer
won't stop. now no matter what i do each time i insert my
hd 5770 the computer won't boot. it just displays blank screen
but sometimes it displays and starts to boot but when i look at
my device on my computer it i can't see the hd 5770. its like
computer can't detect the card. but the card's fan are spinning.

what kind of power supply do you have
it sounds like the psu can't handle the additional load of the gpu

I have the same exact problem but I'm using a gigabyte radeon HD7750.

This is my machine's spec:
Dell studio 540
Intel Q8200 Core2 Quad 2.3 GHz
6GB DDR2 RAM
350W generic PSU.

The same exact thing happened to me. I was playing world of warcraft and suddenly the screen turned black, keyboard and mouse not responding and when I tried to reboot the box, nothing happened. I took out the card (brand new just got it on monday) off the PCIe slot and the computer boots fine. I plugged in my old NVidia 7600GS and everything works fine. After that I tried the new card again and it worked for a few hours and the same thing happened. After the 3rd time happened I couldn't use the new radeon card at all. I just shipped it back to newegg to ask for a replacement card but seeing this now I'm thinking that maybe the card was fine?

Can anyone help us with this?

Hello alfie033,

As what alvine mentioned what power supply do you have? Stock 5770 requires a minnimum of a 450W PSU (good quality one).
