Event Viewer Errors and more

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!

Server Question

It's been awhile since I have had to do something like this so my mind is a bit fuzzy on what all needs to be considered to get this to work right. What I want to be able to do is just push apps down without having to go to the persons computer and do it myself. It would run and install itself without any real user interaction. And if needed do more than one but a list of programs if need be.

Virus/Malware

i had a friend bring over his PC after opening a attachment in a e-mail that installed something called antivir XP 2008 i thought it was just malware he got on his computer but when i went to go wipe his harddrive it will show "loading windows configuration" the black screen before the blue when installing windows again and then the thing reboots itself, i was thinking maybe it was a boot sector virus but im not sure. Could it just be time for him to get a new hard drive and that would fix it or is there another way? (on a side note i did find a way online to manually remove the program but that still didnt really fix the damage it already did to his machine)

EDIT- correction i just tried a fresh hard drive and it still wont load up a windows XP disc that i know 100% is a good disc it will still just get to the inspecting configurations part and reboot with error "NTDETECT failed"

windows wont install

i have a HP compaq computer, had OpenBSD on it and i got rid of it, fdisked and removed all partitions, tried to install windows and it says a file on the disk is corrupt...but its never the same problem twice...you reboot it and it might go alittle bit farther and say another file is corrupt...the disk is good i installed windows using it on another computer same day, the hard drive is not bad as far as i can tell as i have switched harddrives out with a known working one and tried to install windows and get the same type error messages when installing windows. so any advice would be great.
