My computer that's running Windows 7 detects all flash drive file systems as RAW, and thus shows an error message to format them as soon as they're plugged in.
I tested all the flash drives in other computers and have no problem and their file system is FAT32.
How can I fix this issue?

Hope you've tested all USB front and back ports? Suggestion: Disconnect all non-input USB devices, then in Device Manager try deleting all USB root hubs and controllers (best to do it with a PS/2 keyboard or via Remote Desktop, because your USB mouse and KB will stop working). Reboot and Windows will reinstall them. See if that helps. Also run
sfc /scannowfrom an admin command prompt. If this is a hardware issue though you'll need to get a new motherboard or perhaps an add-on PCI-E card that supplies USB ports. – Karan – 2015-05-12T04:20:42.077
