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.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If they are random, then I suspect you're getting memory errors, or possibly disk errors.  Try doing a memory test from the BIOS - I think most BIOS code now provides this capability ...

Sorry it took so long.  Testing ran over 12 hours with no failures.  Used the memory test that windows provides.

I saved the system and application event logs if they will help, but it will not allow me to upload evtx files.

What sort of errors are being recorded in the system log?  Take a look for things that are happening repeatedly, rather than one off errors - that might give you a clue.

Also, try to determine when this started happening, and ask yourself "what changed?" around that time.  Did you update any software or install anything new?  Did the usage of the system change in any way?  Was the system moved?

Another idea: try a clean boot - basically booting Windows without any extra drivers, etc.  Then give the system a bit of a workout - just make it do some work, whatever you have available.  If there are no errors, then start adding back in drivers and other software to see when the problems restart.  (If you need instructions on the clean boot, then there's a Microsoft support article here: http://support.microsoft.com/kb/929135.)
