The NDIS is of course related to you network card
The unknown indicators are most likely kernel drivers
That all said, apart from a suggestion to check if a driver for the network card or a chipset driver has been updated by some auto update program you have running, I have to be honest and tel you I do not KNOW.
I will do my best to get someone more experienced at this aspect than me to have a look for you.
I keep on thinking ram issue, but I would expect other symptoms.
Please do this
AFTER trying the network card and chipset update.1.
CHKDSKOpen the
Computer option from the start menu, which will display all of the drives available to scan on your PC:

Then, right click on the drive you wish to scan for errors and select
Properties:

Now click the
Tools menu, then
Check Now under the error-checking section:

You have several options within the check disk tool. It is always recommended you leave the "automatically fix file
system errors" box checked, as this repairs and problems found. If you want to perform a deeper scan, tick "scan for and attempt recovery of bad sectors". This second option takes longer, but is worth doing if you suspect a drive problem. Once you are configured, click
Start:

If you try to check a disk that is currently in use, you will receive a message asking if you wish to schedule a scan. Accepting this will perform the scan next time you restart your PC:
