Boot to safe mode by hitting the F8 key on boot. When in safe mode, go to a dos prompt and type MSCONFIG and hit the enter key.

In there, select DISABLE ALL near the bottom right and click on OK. You will receive a message that the system must be restarted. Restart it. If the system comes up, you will have a prompt that the system is using a modified boot. Just check off the check mark area and continue. You can then enter MSCONFIG and start enabling things until it locks up again and then you will know that, that is the program causing all the problems.

If that doesn't solve the problem, you may need to reload the OS.

Aside from hardware many things can slow up your PC:

• If the C: drive is too full Windows is unable to allocate a proper virtual memory cache on the drive.
• Your chosen anti-virus solution can even slow certain machines down (post what your running)
  
• A high % of the time it is spyware/malware related

Probably a memory problem even though it doesn't show up on a memory test. Enter the bios and select the option for default setup, "not the optimized setup". Also if you have more then one memory module, remove one and try the install, if you have two try using the one you removed first as the only memory module during the install process. If you have any cards plugged into the computer, remove them all before starting the install. Also all usb cables. Make the system as simple as you can for the new install.

I put my money on that you have a CPU over temperature problem, and/or intermittent RAM problem.

Be sure you are ESD safe when working on the electronics as follow !

I suggest, using a eye piece magnifier and a wooden tooth pick and carefully touch each pin of your RAM sockets and see if the soldering is bad, allowing the pin to move slightly. If that happens, well it needs re-soldering there, make sure you use leaded solder, not the ROHS crapp.

If that turns out to be ok, then check your processor. It might over heat.
You may want to observe if the CPU fans runs at all and if it runs at full speed most the time, even if you don't run any 'heavy' programs. This usually would indicate poor heat dissipation. Most Sony Laptops have a piece of thermal foam pad is used for heat transfer from the CPU chip into the heat sink. Over time this pad shrinks, effectively impeding the heat transfer causing the CPU to over heat and intermittent shutdowns ect. I suggest, find a new piece of thermal pad or replace that with a piece of copper sheet material and use Thermalloy transfer paste.
