random object errors

I am getting indication of bad objects has I start the machine.  They appear to be random and the next time I boot they are different objects.  Also, the signon to the network sometimes but not always is very slow but eventually works.  This is happening on Windows 7 pro sp1 32 bit.  Cpu xeon 3570.  18.0 gb memory.   All updates applied.  No problems found with the system disk using speed fan or chkdsk.  Malwarebytes and security essential find no problems.
