I seem to have had a few strange issues recently that were apparently caused by an out-of-date BIOS. Just the simple though risky operation of re-flashing the BIOS to the latest version, has fixed the problem.Problems like updating memory in old systems, where the latest purchased sticks of memory aren't accepted by the motherboard, installing a new CPU (Processor uCode missing), unreliable booting with integrated graphics, etc. have all been fixed by newer BIOS versions. I've always been a bit hesitant to perform BIOS updates as if it goes wrong can be the quickest way to trash a motherboard. So carefully checking the exact make, model and revision of each motherboard is essential. Always get your BIOS update from the motherboard manufacturer's website as the are many 'tweaked' BIOSes out there which could cause problems. Read and follow the instructions carefully. Some like DELL can actually be done from within Windows, some directly using a DOS program from a floppy and others direct from a USB memory stick.
