Keep in mind that BIOS version numbers are irrelevant between different PC models. So BIOS A06 on the XPS 8300 is totally unrelated to BIOS A06 on the Inspiron 570. BIOS A06 for Inspiron 570 is here. Read/follow instructions carefully.  It's safer to install this update using a bootable USB stick, rather than inside Windows. You can create a bootable USB using Rufus (free). Then copy the BIOS .exe file onto that USB. You have to completely power the PC off even if the USB is already plugged into it.  Then power on, tap F12 and when the boot menu opens, look for option to boot from USB. When it gets to the "DOS prompt", type in the exact name of the BIOS file on the stick and press Enter. Leave the PC alone until the DOS prompt reappears. Then reboot and -hopefully- it boots with BIOS updated. NOTE: There is always a risk that a BIOS update fails and bricks the motherboard, so you do this at your own risk...
Greetings all. I just did a fresh install of Windows 7, 64 bit, and SP1 on my Inspiron AMD Athlon II 570 desktop. When I checked my setup via "msinfo32" I saw that the BIOS version is a "03", where my XPS 8300 uses version "06". Should I update the BIOS to the "06" version? If so, what's the best way to go about it? Many thanks. Cheers.
Reinstalled Windows 7 OS with SP1. BIOS shows version A03. Should I update BIOS?
