First thing I would do is get a can of compressed air, ground yourself and remove the memory modules. Give the slots a good blow with the air and then firmly reseat the modules. Repeat this process for any PCIe and M 2 slots you may have. Then boot up again. If problem continues check for BIOS updates, otherwise might just be bad motherboard, poor power etc...

My PC has this strange failure in which it completely freezes and stops responding to input. This happens seemingly randomly, often multiple times a day, and I have to force-reset the computer each time it occurs. The dedicated GPU continues to output video, albeit only a frozen picture. It's been becoming steadily more frequent over the course of a year or two. I've ruled out storage failure, as it's happened with the operating system on two different drives on different motherboard SATA ports. Maybe it could be a motherboard or CPU issue? I can't rule out the possibility that it's a software problem either, but that seems unlikely, as it has frozen with different Linux distributions. Debian 12 is what I currently use. What is particularly puzzling is how it doesn't freeze instantly, but over the course of a second or two. The first sign is the user interface of applications such as Firefox not responding to clicks - even when the content that it is showing continues to respond. The system time stops updating (I have it set to show seconds, so this is easy to spot). The keyboard input stops working, which I can tell because the caps-lock key doesn't toggle the associated LED. The GPU fan spins up to full speed. To add to all of that, not all of these symptoms occur each time! The only constant is that the system is completely frozen by the end. There's also an issue where one or both of my audio interfaces (one PCI+FireWire, the other built into the motherboard) fails to initialise, and usually requires a reboot to start. Occasionally restarting pulseaudio by itself does the trick. I can't tell if this is related to the freezes or not. This one really has me stumped. Any suggestions for diagnosing this would be much appreciated! Many thanks, Sebastian -- The Mailing List for the Devon & Cornwall LUG FAQ: https://www.dcglug.org.uk/faq/ |
