Sapphire radeon hd 5450 crashing

[rajeshravindranc]

for the past one week i have been trying to resolve this issue...but dont know what went wrong..
my monitor just shows a red screen and then goes black and just blinks the signal light....even if we restart the system,the blinking LED with
black screen continues...then i have to remove pc from power ,wait for 5 minutes then everything goes fine..
whats interesting is that even if the computer is at idle this happens .I checked the gpu aswell as cpu temperatures and they are at 52 and 45..
if i switch to integrated graphics everthing goes fine..
i updated my CC to latest and no change..
I am pretty sure that my psu can handle the card.
Pls help

PS?.......... ( power supply ) make and model.

check for dust build up on heatsinks and fans.

have another card to try?

have another cable to try?

if you are using the vga socket............. do you have a dvi to vga adapter so you can try a different (dvi ) connection?
