Dell inspiron N5010 erratic shut down issue

[kamel]

Dell inspiron N5010 has erratic shut down issue, most times at P.O.ST screen, others long time after windows login.

Steps already taken :
-Fan cleaned, new paste added for CPU and GPU
-Ram and Hard drive tested ok-
-Tried Dell diag tool, lap always rebooted at different steps with no error message.

Did anyone experience this situation with N5010 or have any clue as where to dig further ?

A prompt reply should be largely appreciated.

Thank you

do a visual check on connection of daughter board, make sure no loose connection or oxidation

does the bios give you the cpu temp?

i'v seen a couple of laptops where the heatsink didnt sit flat on the cpu.
it wasnt an issue with the original blue squishy pad, but it WAS a problem when using paste.

check ATI gpu temperature. if it so hot , should be replaced . i did it many times.

Done and also sprayed a contact cleaner, unfortunately it didn't help

No temperature mentioned in bios setup.

cpu temp seems normal.

GPU temperature may be a little high, I'll check it with an infrared thermometer tomorrow and feed back.

Is the fan spins in high speed?

Sorry for the late feed-back.
Measured temperature with an infra-red thermometer, Lap shut down sometimes at 55°, others at 70°.

After making some experiments, I'm likely to think of a GPU heat issue, due probably to the heat-sink not sticking closely to GPU. Heat-sink is screwed only from one side (bad design).

Will try to find out another heat-sink and see if solved.
