Windows 7: BSOD playing any game or just using PC

My computer has been getting a lot of bluescreens. I used to have windows 7 home premiumbut started getting blue screens at one point. I updated to windows 8 a couple of days ago and even more bluescreens. there are many different bluescreens like driver power failure and DPC violation smth and one that seemned to be in connection with the nvidia driver because it said nvldmk.dll i think not 100% sure. it would be pretty nice ifthere was any possibility to get rid of the BSODs.

I noticed some drivers missing, Can you go to device manager and confirm that all drivers are installed!!

Problem Devices:
Base System Device PCI\VEN_14E4&DEV_16BE&SUBSYS_05041025&REV_10\4&BC62EF4&0&02E0 The drivers for this device are not installed.
Base System Device PCI\VEN_14E4&DEV_16BF&SUBSYS_05041025&REV_10\4&BC62EF4&0&03E0 The drivers for this device are not installed.

Try the "Fix IT" on this page.
"Display driver stopped responding and has recovered" error in Windows 7 or Windows Vista

The device manager says that there are 2 base system devices without drivers. But it doesnt say what devices these are so i dont know how to search for drivers for those since the windows auto driver update doesn't find any drivers.
