Event Viewer Errors and more Options

[Neton]

I have a computer on my network that is giving me problems. Every morning when the user first logs in these same errors pop into the event view Event error 1053, Event Viewer error 15, event viewer error could not execute GP script

Steps I've taken so far is, I've scanned for spyware/Viruses and it came back clean(using Malwarebytes, Hijackthis, and Symantec anti-virus corp ed.)
The problems these are causing is group policy isn't being applied, and network drives aren't being mapped. I know the last resort if this isn't a easy fix will be just pulling it from the network and re-imaging it, but I figured if there was a easy fix to this that I don't know about I would try that route first.

So any suggestions will be appreciated and thanks in advanced!
