and dont start to work untill i restart my computer.
anyone else got this problem, or know what to do?

Bump, i really need help guys

This may or may not help, but is the one client that is lockup up running questhelper? There are some known unresolved bugs where questhelper can crash clients. Once I hit 70 on my shamans and got rid of all my quests and started doing just dailies I could no longer run questhelper on my shaman team without crashing. Works just fine on my leveling teams.

If you are not running questhelper try disabling all your addons and playing for a bit. It could very well be because of some addon that is out of date and causing issues.

Tnx for actually reading and trying to help me, i dont run questhelper and it didnt work. im starting to think its my graphic card who dont seem to work out, my processor should be ok , heres some of my hardwares:

Pentium4 3.4 Ghz dualcore
1gb ram(maybe this is the problem?)
Radeon x1300 series 256mb

I would try running just the instance of wow that crashes for a while and see if you still get the issue. If you do this and have all addons disabled then you should be able to get help on the wow technical support forum. Isolating the issue should be your top priority at this point and doing both steps will help in that regard.

I recall having the same issue several months ago when I ran all my instances from the same folder of WoW. I solved the problem by making three folders of WoW.

okok, tho i already got 3 folders. ima try with 1500mb ram now, if it works i'll buy 500mb more,

Your RAM is a little low for running 3 instances of wow. What FPS do you have going on your main and clones? If you did not throttle it down you will have issues with your set up, I have 4Gigs of ram in my machine and sometime it runs slow.

I throttle my main to 45fps and my clones to 15fps and it runs well, I could probably go up to a lot more but it works perfectly well at 45 and 15 for clones. It slows down some when I start my 4th account.

Well marious, i have trottled it down, MUCH! :P ive been searching for the fault and now when i throttled the clones down to 5fps (lol yea i know) and main 25fps it takes 1gb of ram, so im off buy 1gb more, then i got 2gb, if i makes it go for about 15 fps on clones and 40 on main u think that should work?
btw all, Ty so much for trying, it hasnt crashed a single time since i put in 500mb more in ram

GOD i love multiboxing:) when i reach 70 with these shammys im off to run hunters, (Wotlk ftw) and since ive reqruited myself i can give 60 levels, and im gonna give em to a 24 warrior:P :)

LOVE YOU GUYS! <'3

Well, you made two changes: Added RAM and reduced FPS. So while you know one of those caused the problem, you don't know exactly which one. While adding RAM is always a good thing to help PC performance, my bet is the X1300 is not quite up to the task of running all your clients at a higher FPS. I would spend the next day or two playing with the RAM and your current reduced FPS to make sure your system is stable. After that, then start bringing your FPS up and see if it starts crashing again. If not, congrats! If it does crash then lower your FPS until it stops crashing or buy a new vid card.
