Okay I will try to explain in more detail,..  The processor gets totally  blocked up (clogged up) for the entire duration of any render, no other software will work.  If it does it is Very slow..
For example it took about 15 seconds for the screenshot to be taken..  Internet browsing is almost impossible with certain sites ( including Rendo ) giving me timeout messages..
Can anyone understand the frustration  this causes..  And please don't tell Me I have a problem with My attitude.
