BSOD While Using Switchable GPU

post #1 of 2
Thread Starter 
I recently purchased a Lenovo Ideapad y560 i5 with switchable graphics.

Recently, I started getting BSODs and graphic errors when I used my ATI card (non-dedicated).

However, if I switch to my intel graphics, I don't receive BSODs and everything works fine.

Here's the file from the dump if anyone can analyze and tell me what's wrong. I'm pretty sure it's my GPU but I just want to be sure.

Thanks in advance

my Lenovo Y560 'Core i5 460m' have GPU problem
ii believe my GPU (HD5730) is dead now confused.gif
when ii start in dedicated graphics mode in the bios
all bios & everything is blank nothing on the screen
its like windows is running 'without a display'

after restarting in switchable mode
the display come backs to life

u cant see the bios, THE SCREEN DOES NOT SHOW EVEN BIOS IN DEDICATED MODE mad.gif
so ii did it by counting arrow keys TO REACH SWITCHABLE MODE in bios, one time 'right arrow key', 4 times 'down', then 'enter', 1time 'down key', 'enter' & 3 times 'right' again then entering it 2 times to save bios settings hypocritesmiley.png

ati hybrid drivers didn't worked, ii usually use LESHCAT DRIVERS thumb.gif
device manager shows only 1 standard VGA graphics adapter instead of 2.
after installing non-hybrid driver formerly known as the official intel hd display driver
device manager shows intel hd only

switch is not working still the switchable lights glows all the time
the heat is doubled than ever & battery last long to 1hr & drains in power saver mad.gif
the dead GPU still produces the heat as its inbuilt on moterboard

Solution:
ii tried bios update more than 3 times

used different display drivers (unofficial)


Lenovo support told me to change motherboard
the display chip has been malfunctioned
