I am sorry for not realizing my multi posts, it won't happen again.
As for the type of beeping it is a continous 1-2 pattern beep / bong , beep bong etc....
This will not stop until I physically turn off the power from the power strip I use.
It happens at random times regardless of what I am doing on my pc...but seems to happen more when i defrag or run a virus scan or play a pc game like total war
I will try the canned air and cleaning solution ASAP
As for the power supply being bad I hope not, the only way to check that is to hook another one up to the machine I suppose....
And bad RAM I would have to take one piece of 256 out at a time, do u think my MB may not be able to handle 3 sticks ?
I did not read any limits via my MB manual....
