I need a little help to figure out the panics my system is experiencing.

My system -
Gigabyte G41M-ES2L motherboard,
Intel Pentium Dual Core E6500,
2GB DDR2 800MHz/PC2-6400 RAM,
Western Digital WD3200AAKS 320GB SATAII,
Sony AD-7240S 24x DVD±RW DL & RAM Internal SATA,
MSI 8400GS 512MB DDR2 DVI VGA Out PCI-E Graphics Card

I successfully installed 10.6 retail using a combination of Boot132 cd and USB stick with a copy of the snow leopard DVD and myHack installer.

I upgraded to 10.6.2, and installed the 10.6.2 compatible sleepenabler.kext.

Everything was working perfectly for a day or so, then attempting to wake from sleep I was presented with the light blue screen (which I took to be a crash). I then rebooted the system via the reset button. The boot process got as far as presenting the Apple and loading animation, then the "you must restart" screen appeared.

Reboot was attempted a number of times, each resulting in the same panic.

Ok, I thought, maybe there's something wrong with the HD. Something that disk utility could fix.

So I tried to boot using the USB stick SL installer. The pre boot worked as usual, then selected the USB installer to boot. After the apple and loading anim screen came the panic screen again.

I thought this was a little odd, as previously never had any problems booting the USB installer.

I tried booting from the USB using -v and got the following screen:


Then tried booting from the HD with -v:


Basically, I'd like to know if anyone could shed some light on my problem. I do wonder if it might be a hardware issue rather than software, given that it panics on both the HD install and the USB stick.

I did some further tests - Removed the gfx card; same result. Removed the HD and booting via Boot132 and then USB installer; same result. Re-seated the ram in slot 2; same result.

Could the problem lie in a bad RAM DIMM?

Cheers,

Matt
