Crashing or BSODing randomly when playing games

[CatastrophE]

Ok everyone, I have a nasty problem, after recently changing my Mobo and Processor I did a repair of windows XP and had pretty poor performance and slow running speeds, I installed drivers and such which appeared to fix my problems however when running games I would find (specifically with HL2 and Vampire The Masquerade Bloodlines) they would randomly crash to desktop at any given time, sometimes with BSOD or Restart of PC or sometimes with an Error Log explaining what went wrong (albeit not very specifically) to counter this I put it down to my lack of a clean install of XP, so I bought a new HD and did a fresh XP install and kept my files on my old HD to avoid problems, All drivers appear to be latest, and the slowness seem's to have gone, all problems are fixed...except my games still crash to desktop with the same Minidumps and BSOD's and all that crap, ive tried basically everything to no avail (chkdsk, reinstalling drivers, looking for conflicts etc etc) I decided to check over my Error logs and Minidumps, it appears that as i've gone along the line installing new drivers and such, i've been getting less error's until only one remains, a DRIVER_CONFLICT with atikvmag.dll...
now I have no idea what to do since i'm at a total loss as to what's causing all this crap, and have been trying for a whole week to fix it to no avail, ive got a feeling it's something obscure rather than serious, so i'm hoping that by giving you some Error logs and Minidumps to look at you guys can help me out, this is driving me mad and I just dont feel like my PC can be used for leisure anymore as long as this carries on

KERNEL_MODE_EXCEPTION_NOT_HANDLED_M (1000008e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: bfa620ea, The address that the exception occurred at
Arg3: b81789b8, Trap Frame
Arg4: 00000000

Strange, ive fixed it.
It seem's a week of crap finally paid off.
I (pointlessly now that this breakthrough occured) uninstalled, clean sweeped in safe mode, and re installed from Omega to latest Catalyst (this didnt fix the problem sadly) then I went into Bios and noticed my memory was forced to DDR400, which is fine...or so I thought, I decided to set it to Auto and set AC97 to FORCE audio for me, i'm not sure which one fixed the problem, but I did notice it scaled my memory down to DDR333, although I must confess I dont notice any difference in loading or anything, in fact everything seem's perfect, only without crashes to ruin my fun
Re did my 3D mark 2003 and got more Marks than I did originally with my Omega Drivers, so i'll just stop messing about incase it all goes wrong again lol, was tempted to re install Omega's but nah, i'll just forget that one, yeah.

3D Mark 2003 = 11805 Marks or something to that degree
