The PC has a Gigabyte GAMA-790X-DS4 mobo and an AMD 8650 Triple core processor with 4 GB of RAM. I am using a PC Power and Cooling 750 watt PSU , 2 Raptors running RAID 0 with 2 Seagate 1TB Harddrives. I have a Samsung SuperWriter DVD, LG Blu-ray Disc Rewriter GGW-H20L, ATI-Radeon Sapphire 3870 and a Zalman CPU cooler in a CoolerMaster Cosmos case.

I have been experiencing erratic mouse functioning where one moment it works perfectly and the next minute it is very reluctant to move. I also have lost BOTH of my optical drives thereby making re-booting from my Win7 Pro disk impossible. I have a backup image of my C drive but I need to reformat my drive. When I go to the Device Manager the optical drives had the exclamation points in yellow triangles that I attemted to uninstall the drivers many time but was unsuccessful in fixing the problem. I went to the Microsofts Solutions site with no success and finally, I attemted to use the Fix-it tool from Microsoft that also did not work after being tried a half a dozen times. CODE 43 is mentioned in the Device Status. What is CODE 43? How does a PC that was functioning PERFECTLY suddenly go south like this? I have Avast anti-virus, Emisoft Anti-Malware,Adaware and Malwarebytes that have up to date definitions and all show clear and OK. I'm stumped - What should I do?
Oh yeah, my printer has vanished too.

Code 43 in Device Manager means Windows has stopped a device because the driver stack reported a problem. It is a generic signal — sometimes a bad driver or registry filter, sometimes a failing controller or power issue. When several devices vanish at once (optical drives plus a printer), this usually points at a common layer: drivers/filters, the SATA/USB controller, or power/motherboard. This expands on ’s note that it can be either hardware or drivers and is targeted at ’s symptoms.

Quick diagnostic checklist (in roughly this order):

  • Check BIOS/UEFI to see whether SATA-connected optical drives are detected. If not seen in BIOS, suspect hardware or cabling.
  • Reseat and swap SATA/data and power cables; try a different SATA port and a different power connector. Test an optical drive on another PC if possible.
  • Boot a known-good Linux live USB (created on another machine) to confirm whether hardware is visible outside Windows.
  • In Windows Device Manager use View -> Show hidden devices; uninstall devices with errors and any non-Microsoft filter drivers, then reboot and let Windows rediscover hardware.
  • Inspect Event Viewer (System) for device/driver error entries — the failing driver name there points the fix.
  • For optical-drive-specific Windows fixes: after exporting the registry key, delete UpperFilters and LowerFilters under HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}, then restart.
  • For the printer: restart the Print Spooler service (services.msc) and reinstall its driver; try different USB ports/cables.

If devices are missing in BIOS or fail under a Linux live environment, suspect PSU or motherboard/controller failure — swap in a known-good PSU or try the drives on another board. If problems only appear inside Windows, focus on driver/registry repair and system-file checks (sfc /scannow). Always export/backup the registry and system images before making low-level changes.

It can be a hardware thing, either the power supply or the motherboard aren't doing their job providing power to the components.
Or it can be a drivers thing, download updated drivers, try this site driveragent.com to see what you are missing.
