No Onboard speaker beep during boot :(

My computer is about 8 months old now and it recently started developing problems. For the last month it would blue screen and I already fixed that. It was due to corrupted files on the OS that windows 8 wouldn't work properly and kept blue screening. Fast forward about a week or two. Now when I booted it earlier it was perfectly fine. I went to the bios and changed it from "High Performance" mode to "Power Saving" mode. When it was restarting the onboard speaker started making weird beeps. There were two short beeps and one long one. This pattern would repeat over and over again. I also noticed that the DRAM LED was red. So I unplugged everything and checked for loose hardware and nothing. I decided to try booting. My computer booted but this time without the normal "beep." There was nothing at all.
I decided to run Prime 95 and 2 out of the 8 cores failed the test.

Specs:
CPU- AMD 8350
GPU- Sapphire r9 270
PSU- 80plus bronze 750w
RAM- Gskill 8gb 2400
MOBO- Asus m5 a97 r2.0
Hard drive- Seagate 2tb SSHD

I just checked on CPU-z and my Cpu is constantly running on 4.3ghz. When it was new it was running 4.0ghz. Perhaps I mightve changed something on BIOS that caused this change. Hmmm. Would you happen to know a way to reset everything back to the factory settings in BIOS? Thank you :)

Quick Update: I went into Bios and changed the ai tweaker into auto and restarted and now the Cpu is running 4.0ghz. Just did a prime 95 test and every core passed except core #8 :( After two minutes of testing, core #8 had an error and the worker stopped :(

Here is what it says: "FATAL ERROR: Rounding was 0.5, expected less than 0.4. Hardware failure detected, consult stress.txt file."

Any ideas? Thank you again :)

When you go to Save & Exit in the BIOS, there should literally be a "Restore defaults" option in there and that'll reset your BIOS :)

Make sure your Boot Drives are set up properly after you do that, if you have multiple hard drives.

I'm not familiar with that specific error. Some brief searching implies it's still an unstable overclock. Try resetting your BIOS first to defaults and let me know how that works for you.
 
Suggest you check and record your voltage values before you follow the excellent advice of reverting the BIOS settings to DEFAULT. Most bios require you to do an explicit SAVE after you reset to defaults. If whatever tweaked you to 4.3 ghz also shot up your CPU voltage you want to know it.

Overclocking with high voltage can cause the CPU to fail internally. That said, the ability of PC software to isolate an error to CPU, MB or memory or PCIe device is really weak. I would not trust that a core is broken because prime told me it was. I would believe that there was a problem somewhere and debug it. For example, remove 1 dimm and run prime again -- same fail? Now use other dimm only and run prime again -- same fail? If so I'd tend to believe a bit more that the CPU was at fault.

Hey, thanks for your input. I don't do a whole lot of overclocking, so I wasn't sure what to tell him to look for. This is helpful next time I see someone asking about this. :)
