New Build, Comp Freezing :*(

[eromdiksnelladivad]

I completed my first build recently.
Everything was working fine. However halfway through installing NORTON ANTI-VIRUS I canceled the installation and tried to uninstall what was there. however it still was showing up on my programs list and I couldnt get rid of it. After this my computer started freezing, I started rebooting and it still kept freezing. So I reformatted with windows xp, that SEEMS to have fixed the prob. No freezes for 3 days..
I thought it might have been overheatting my system idles at 33 degrees Celcius, Is that hot for a computer. Can Norton Anti-Virus ruin Systems?
Im very worried, its my first build and I put 700$ into it so far.
Something Else im worried about; when I applied the grease to the CPU (which the heatsink goes over) A section of the cpu wasn't completely white with grease as shown in the picture, it had a layer of grease over it, just not enough for it to be completely solid white, I did my best to spread it evenly but It just seems as if I didn't get enough grease in the small tube that came with it. Could that cause my comp. to freeze when it did??
Any help appreciated, thank you!

Actually, too much grease is worse than not enough. Spread it out REAL thin and even. 33C at idle is VERY nice and cool.

Norton can do some REALLY nasty things - I'd recommend you forget about it and put AVG Free on it.

Phew, so you think it was probably Norton too?
Hopefully it was and it never ever freezes again, I wasn't aware that legit software would do that too a system; I guess im naive
Im really paranoid
Thank you
