HIS Ati Radeon 7850 random restarts even in BIOS

My System keeps shutting down after a few seconds. Yesterday, it was at least working for 2 to 3 hours but now it keeps restart even when I’m in Bios. It is just like as if I pulled the plug.
Sometimes , I get the following error message:

The "OC failed" message , comes up as a part of the BIOS while startup.

"American Megatrends "
Overclocking failed…
f1 to setup
f2 to default values…

I have never overclocked. I didn’t updated the BIOS. I have also tried clearing CMOS but no luck. The temperatures are normal and voltages were Something like 3 = 3.2, 5 = 5.1, 12 = 11.5. I already checked the temperatures and they were fine.

I bought the card 27 days before and I was having same issues at that time. Then I thought it might be the motherboard so I took my system to Asus service center but everything worked there. So I brought back my system but then I faced the same old issues like idle freezes, random restarts after 30 minutes, sometimes it worked for 3 hours or more. Finally it worked for a week by underclocking the card.

Now again I’m facing the same random restart issue even at the bios screen. I took out every component one by one and found that it was Ati 7850 that was causing random shutdowns. Now I’m clueless….

My system specifications are:

1)ASUS Sabertooth X58 LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
2)Intel Core i7-950 Bloomfield 3.06GHz 4 x 256KB L2 Cache 8MB L3 Cache LGA 1366 130W Quad-Core Processor BX80601950
3)CORSAIR Vengeance 16GB (4 x 4GB) DDR3 1600 Desktop Memory Model CMZ8GX3M2A1600C9
4)CORSAIR Enthusiast Series CMPSU-850TX 850W ATX12V v2.2 / EPS12V v2.91 SLI Certified CrossFire Ready 80 PLUS
5)Cooler Master V8 (CPU COOLER)
6)HIS ATI HD 7850 2048MB - 256BIT - GDDR 5

Please Help!!!

  1. You need to repair or rma that card.
  2. I didn't get it, If that's the card then how it worked for a week without having issues like freezing and restarts. Isn't there a better solution rather than RMA?
  3. Sometime card fail at first day or sometimes after usage for sometime.
