A Dreaded Bluescreen

[Katvood]

Alright Lads And Lassies!

I don't really know where to start with this problem But Lately I've been getting a blue screen, Usually when I Try and Open A Programme, But Even Small Programmes that shouldn't cause any stress to my computer Like Mozzila.
I'm Not 100% sure of what's caused this (Hence Why I'm Here ) but I Updated My Grafx Card The Other day To try And Get Cities XL To work (Which Didn't Help) And Ever since I Have been getting this bluescreen.
I have tried to roll back the driver but Any Time I Do (Give it a few seconds) And I Get The Dreaded Bluescreen yet again.
Call Me Stupid for This But I Don't actually Use Any Antivirus Software, Because I Play alot Of Online games and The Software generally just creates problems By Blocking things All the time , So It could also Be A Virus And If It Is I Will Have Deffinetly HAve learnt my lesson And Get AntiVirus Software!
But As Soon As I Try and Install AVG I Get the Blue screen again -_-

Thx Guys Hope You can help

Go to START > CONTROL PANEL > ADMINISTRATIVE TOOLS > COMPUTER MANAGEMENT > EVENT VIEWER and look at the SYSTEM section for any errors with a red cross.

Report back what they say.

Sorry For the Late reply man. This Is All of them over the last few days

The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{BC866CF2-5486-41F7-B46B-9AA49CF3EBB1}
to the user NT AUTHORITY\NETWORK SERVICE SID (S-1-5-20) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

That's the first one ^

Unable to initialize the security package Kerberos for server side authentication. The data field contains the error number.

That's the second one ^

\SystemRoot\SysWow64\Drivers\ASPI32.SYS has been blocked from loading due to incompatibility with this system. Please contact your software vendor for a compatible version of the driver.

that's the 3rd one ^

\SystemRoot\SysWow64\DRIVERS\dvd43llh.sys has been blocked from loading due to incompatibility with this system. Please contact your software vendor for a compatible version of the driver.

That's the fourth one ^ I think these are the two that are causing the bluescreen

The previous system shutdown at 17:30:20 on 17/10/2009 was unexpected.

That's the Fifth one!

Thank's For your help hope you can help.
