Amd 6300 unstable at stock settings?!

Hello i ran IBT AVX to see how hot my cpu gets under load and it is all stock with its defaults in the bios so nothing is changed i did try to oc it once but the voltages where below safe recommended speeds i found that my bord droops quite a bit so i couldn't get it stable in prime 95 so i put it back to stock.

My board im using is a 990FXA GD65 

But the error is:

WARNING Linpack Binary stopped unexpectedly. 

This could be a result of missing executables, unstable system, or a soft ware bug. If you have UAC enabled please try re-running the program with administrative privileges.

Seeing this worries me.

prime95 is bad. use something like aida 64

And if that fails what should i do.

Whats your power supply and is it new or recycled from an old build?

Its a ANTEC VP650P i brought it in 2014 mid October.

It is just a guess and it may be wrong considering that Antec is usually pretty good but that psu may not be capable of delivering sufficient clean and stable power to your cpu. It is not 80+ rated so I definitely feel it is possible that it is the cause although maybe not the most likely one. It could be that you got the 1 in a million faulty 6300 but I have many doubts with that. Did you touch or bend any pins when installing it? Anything go wrong with the installation?    

Well no not at all when i installed a pre filled liquid cooler. when i took out the stock cooler it did take the cpu with it as the pre applied thermal paste must of turned to glue. No pin where damaged and the leaver was opened and the cpu was fine and was put back in. The part is out of warranty so i cant return it but all appeared to work fine and all pins where not harmed. Windows was re installed as i changed to a ssd and all was fine.

My buddy installed a Corsiar h75 on his AMD FX 8320 and it pulled his cpu out of the socket, but it turned out fine...

so it was stuck to the heat sink when he pulled it off?

Well i found that my CPU is only unstable in IBT AVX

so i have worked out that it is stable because Aida 64 has been running for 3-2 hours and no problems at all 

Thanks for the help.
