Mysterious occasional BSOD, seemingly random.

My first post. Please be gentle...

I just refurbed a used machine off of Ebay, Cloned my W7U64 install from a similar unit that had physical damage into a bigger HDD.

Same CPU and mobo so I am lost why I'm getting BSOD. Before the physical damage, that install ran great for months without any BSOD. If you gents could point me towards a direction, I should be able to fix it *crosses fingers*.

Muchas grassy ass...

Welcome
You have given us 3 dump reports all different. This is usually an indication of hardware problems, although more confirming dumps would be required to make a definitive analysis. One of your dumps mentions memory, however, so lets start with that
Take memtest86

Well, I originally skipped MEMTEST86 on this rig since it lacks an optical drive. I guess that figures.

Since I can't run it until I get a drive for it (I don't think the BIOS allows boot from USB... The BIOS is really limited), I just took out the smaller SODIMM and used it for a day. No BSOD so far, so that might have been the culprit!

Thanks for your help.

Cheers!
