Hi Patatrak,

If 1 & 3 are flashing (along with the power button flashing amber) it means the PSU has an issue.

If 1 & 3 are solid (and the power button solid green) it points to a memory error. If it's a memory issue, try disconnecting then reconnecting the memory sticks. If that doesn't help, try each memory stick, one at a time in each slot to see if you can narrow it down to one stick or one slot.

Let us know how you get on.
