XPS L502X COLD FREEZES
I own a xps l502x laptop for over a near now. Whenever I try to run a application on NVidia GeForce graphics(gt 540m), the system after a minute or two, cold freezes with a annoying buzzing sound. I did several tests like memtest86, prime95 cpu and mem test, furmark test for GPU and all the tests passed.
Then I read on another forum about running tests with PC Doctor but the test couldn't complete as the system again cold freezed. All I could do was use the power on/off button.
I googled about it. I noticed that there are a lot of people with the same specs which are facing this problem and have no solution except for a custom bios which reduces voltages for the GPU or underclock the gpu itself. But I don't want to do this as this will reduce gpu performance
Now I am getting really frustrated with this problem. I paid 70k for this laptop and I expect more out of it.
PLEASE HELP ME ASAP.
my system specs:
Windows 7 64 bit.
intel 2670qm processor
NVidia GeForce gt540m with optimus
intel hd 3000
8 gb ram
