So, for some time my desktop has been having infrequent fits, after which it refuses to start. It hangs right before it tells me about its memory stuff (I don't really know any of the technical names). However, if I insert a specific USB thumb drive before booting, it hangs slightly after the aforementioned point, and prompts me to remove the drive. This may have something to do with the USB having been previously used as a bootable disk.
I realised, then, that if I leave the USB in for long enough for the computer to boot past the initial freeze point, then remove it before the second, the problem never occurs. Why does this happen, and/or how can I avoid it?
PS:
The memory stuff I mentioned earlier; It freezes just before it would normally print the message Memory Runs at Flex Memory Mode
, which is basically my way of checking that the computer will boot or not.
