If PC overheats then is more possible to hangup. I think you drive some electronic on the edge. Ie if you use printer port that is possible to work just in margin and when heat's up then doesn't work more. But another thing is that you say that after that error you can continue work that is wery strange.
And as few people already say. Dry wood dust doesn't harm computer. But they accumulate on all fans and heatsinks and cause problems. Presurized case with fan with filter seems good idea. For monitor's there is no fan so no trouble of that kind should be expected. But if you use old type with CRT (not LCD) then this monitor isn't for dust environment. They have high anode voltage (10 to 25kV depends on size) and that attract dust to accumulate on HV wires. Not good... ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
