PCH A-100 Shutting down after 10 minutes / Freezes on loading

[emillaursen]

Hi!
I have a PCH A-100 that started to act weird about a year ago and if i dont remember incorrectly the problem back then was that the loading screen kept freezing.
As i didnt have the patience back then i just put it in a box and forgot about it up until today.

The first two attempts at starting it worked fine - only that it would stop sending signals to the tv after about 10 minutes of working smoothly.
I pulled the power and let it rest.
Now on the third try it is stuck at the loading screen. And nothing seems to be happening.

My question is simply if there is any solution to this problem.

Some specifics:
Connected to a Lg LCD TV via HDMI.
No harddrive
Connected to the internetz
Probably from the winter of 2009 (bought it second hand) and worked fine for the first year or something.
No idea what firmware installed.

Got it to work for a brief period of time - but now its back to the stage where it works for 10 minutes and then suddenly stops working.

But now i know some more specifics:
- Updated to the last firmware last night.
- Runs it through a HDMI-cable, and the settings are HDMI 720P 60 Hz - the same as my TV.

Any suggestions of what to do?
