Hardware changes might not have been detected

[Barnum]

I have had a myriad of startup problems now for about two weeks. Sometimes my pc starts up fine, and other times I have to go through the startup repair routine, and do a system restore. When I check my hardware after a problem the error indication is always on my PC. I can then fix the problem (drivers missing) by running the fix program but then a couple of days later it happens all over again.

The message is always "hardware changes might not have been detected" Can some one please tell me how to fix this for good. I am so tired of having to wonder if I will have a computer to use each day.

What's about Inside your "Device Manager". Have you some yellow exclamation marks pointed on some devices?

You might want to check if pci or pci-e card are well inserted in their slots, if USB devices are well plugged too....

No exclamation marks...have not checked cards. All USB plugs are secure...thought of that too.

If it comes to it maybe a memtest might be the go it does mean you have to make a bootable disk and set the BIOS to boot from the optical or a USB and it does take a long time - at least 8 passes unless the errors come straight away to do but if the other stuff fails then worth a try.
