(I will have to do this fast, since I think my mac will crash again.)

My Mac keeps crashing. It started happening since I installed Adobe Acrobat Pro (since then I have removed it), but it might be unrelated to that. Even after I removed it, it still keeps crashing every few minutes.

Here is the latest panic log from Console:

What's the battery status? Is it overheating? This sounds like a heat issue to me. – Burhan Khalid Jun 16 '14 at 6:57

A machine-check exception is typically a hardware failure. If you're lucky, it's "just" a RAM failure and if you're super lucky, you can fix it by re-seating your RAM, or (lucky, but not super lucky) replacing a failing RAM card. If you're unlucky, it could be a motherboard problem.

On another Mac, create a bootable external drive (USB, FireWire, or Thunderbolt) with a clean install of a version of Mac OS X that you know your failing Mac supports, then plug that drive into the failing Mac and boot from that. If you still get the machine-check exception, you're probably seeing a hardware failure.
