I'm having a constant problem when playing TES Arena
every 2 or more hours the game locks up completely,
It simply freezes there, without crash exiting or anything
The only way to get out from game is alt+enter and close dosbox

Already tried messing with the cycles/cpu/output on dosbox, but the problem persists
could anyone help
thank you =]

Intel I5 processor
6 GB RAM
Intel HD 4000 Graphics

My suggestion is to not leave the game running for that long. You should be taking a 15 minute break every hour or so anyway, and that break would be a good opportunity to turn the game off.

If you *really* want to play for long periods of time, remember to save frequently and quit the game every hour or so; this way you shouldn't run into the problem you're describing.

thanks for your reply
I think it happens randomly, just played a couple of minutes and the game froze like before
idk what it could be, is this game that bugged?

Just a guess: Some sort of incompatibility with your Intel graphics card?

I have played Arena from the beginning, on a native DOS PC and sometimes for several hours per session, and still play it today occasionally under DOSBox (although rarely more than one hour per session). But I can't remember any freezes.
You could try playing with the graphics parameters of DOSBox.

To save regularly is good advice.

To save regularly *and in different slots* is good advice for every Bethesda game; you never know when you will hit a bug whose effects weren't immediately apparent.

One bug I encountered: If you delete the last spell in your spellbook, the game remains open to that spell, as if nothing happened (but the spell has been deleted); if you delete it again, you lose 2 spell slots *permanently*.

Anyway, one other thing to try would be to increase the amount of RAM allocated to DOSBox; that should at least delay the crash happening, hopefully at least long enough to make the game playable. (Arena's memory management code isn't exactly the best.)
