In my bios it says that my hard drive is running in PIO mode 4 but the option uderneath that says UDMA 2 (I know the computer I am working on is old) how do I turn off PIO mode. Will the hard drive automatically run in UDMA mode or what? The mobo is an A7V333.

Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

Theoretically, the A7V333 supports UDMA Mode 6 (ATA/133). However, most versions of Windows don't. And yes, all BIOSes will set both the highest PIO mode and the highest UDMA mode that the drive supports. And Windows will usually run the drive in the highest supported UDMA mode, but may step down to a lower UDMA mode or even PIO-only mode to protect the drive from data corruption.
And the reason why your drive says UDMA 2 is that the particular drive that you have connected to that mobo is only an Ultra ATA/33 drive.
If the OS is reporting it in PIO mode, it's probably due to head south at any time...
PIO mode is indicative of errors all across the board, IIRC.
That or you just need to change the setting in on the controller in Device Manager. Try that first before jumping to conclusions.
