Start > All Programs > Accessories
Right-click "Command Prompt" and then click "Run As Administrator".

Under the admin command prompt, type:

SFC /scannow

(this will scan your Windows critical files for corruptions/modifications and attempt to repair them)

If that didn't help - Roll back your graphic card drivers...
If using Nvidia - manually download an earlier stable version from: http://www.geforce.com/drivers

Right-click and "Run As Administrator" as well to install.

Consider other rogue 3rd party driver or drivers emulators which might of been installed recently. Do you use xBox controller emulator, a virtual drive, etc?

---

On the off chance - Scan for malware...
Use Spybot or MalwareBytes, update and perform a full scan.

If that still fails, consider disabling your Sleep/Hibernate (depending if you use it or not).

NT Plug and Play PCI Enumerator (Pci.sys) rarely causes problems, it however is the driver which allows your computer to communicate with hardware and connected devices.

Therefore check...
- Driver issue, compatiblility or corruption.
- Failing to wake up hardware after sleep/hibernate (might be due to BIOS + Windows both sleep).
- Driver emulation failed (like an xbox controller being connected as unknown).
- Faulty external devices connected.
- Virus faking as 'Pci.sys' or attempting to inject it (keylogger, etc).
- Hardware power failure (check loose cables or faulty power supply).
