Computer Randomly Locks Up

[LateralShamu]

Have you tried booting to Safemode with or without networking? What is the result? You could also provide all protection softwares installed such as Firewall, Antivirus/Spyware/Malware, Scanner. Depending on how intensive you are using the computer, you could try using one or two RAM modules to isolate them from the issue or run memtest as an option. Another option also would be to perform a Clean Boot .

Yes.  It worked.  No lock ups that I could see.

ESET Smart Security 4

Clean boot has not helped.

ESET Smart Security 4, paid or trial version? Looking at your protection software details shows you have already an Antivirus, Firewall, Antispyware, Antispam. Do you have any other protection softwares installed/enabled that could be conflicting such as windows firewall?

Paid, of course.  Nope, disabled Windows Firewall.  No reason for anything besides ESET.

Well if its not on the software side, then you may need to isolate the hardware components installed by using one instead of 2 RAM, Video card. But if there is a real choice, I would even try removing certain programs or softwares since the issue started to occur. If you are keeping a backup installer, the better. Make sure the tower is not keeping any dust buildups and try reseatting certain components and clean the contacts. Applying a good thermal paste for the processor will also help. Random lockups could mean anything as in software or hardware.
