possible motherboard failure

I have an hp desktop the model is a6720y. It stopped booting and said my hard drive was failing. I took out the hard drive and hooked it up as a slave to another computer. I scanned it with avast and malware bytes which both found a few items i removed and then i chkdsk it and everything checked out. Now the computer will boot fine and let me get into the bios without anything hooked up to it drive related. And for some reason if i leave it off for a bit without a hard drive connected then connect it and boot it the first time it will let me onto my desktop then freeze and next time i boot it freezes at detecting storage devices. I tested the sata cables, psu, ram and cpu and they all checked out so i figure either the motherboard is bad or my bios is corrupted. I can boot from a flash drive without the hard drive connected but wasnt sure what i needed on it it flash the bios. The only things ive found is bios updates that need a os running to install. Any tips would be appreciated

 

Go get the trial of the Pro version at http://www.hdtune.com and run it to check that drive. Most especially, check the health tab for reallocated sectors (05) and pending (C5). If the value in the data column is not zero, your hard disk drive is failing (PERIOD)
You can also run the error scan (not quick) and, if even one red box appears, you found what is crashing Windows.

 

Both those came up as zero but c7 ultra DMA CRC error count has 1488 in the data column and says the status is "warning" gonna run the error scan now

 

In my case i was affected with a kernel bug affecting the pcie_aspm (pci express active state power management), and that affected the sata controller specifically. Each drive will randomly get i/o errors (in the worst case, and other disk error types


found that on another website where someone had very similar issues and only had those errors i did with hd tune. Guess the next question would be how to check for that bug and get rid of it.
