I did a ram test but found no problem.i am not overclocking and also cooling is definitely not a porblem. All my drivers is updated and BIOS is updated.
If it is still under warranty I would rma it but if you prefer not to...

As indicated 124 is a general hardware complaint. More difficult to diagnose.

If, as you say, overclocking, and heat, are not problems its time to start running stress tests to figure which piece of hardware if problematic.
Then, if the above tests pass, I'd try these free stress tests:
FurMark download site: FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net
FurMark Setup:
- If you have more than one GPU, select Multi-GPU during setup
- In the Run mode box, select "Stability Test" and "Log GPU Temperature"
Click "Go" to start the test
- Run the test until the GPU temperature maxes out - or until you start having problems (whichever comes first).
NOTE: Set the alarm to go off at 90șC. Then watch the system from that point on. If the system doesn't display a temperature, watch it constantly and turn it off at the first sign of video problems. DO NOT leave it it unmonitored, it can DAMAGE your video card!!!
If the temperature gets above 105șC, quit the test - the video card is overheating.
- Click "Quit" to exit
