The only two things you can do for a Processor is to,
B.Clean the top of the Processor case, and the bottom of the heatsink that sits on it. Then apply new thermal paste.
I suggest you take this baby right back to this 'Tech', and tell them you need the problem fixed.
Slightly off topic, but I thought I would show you what I'm talking about.
The top of the Processor case is not perfectly smooth. It looks as though it is to the human eye, but it isn't.
There are microscopic hills, and valleys, and 'potholes'.
Same thing with a Heatsink. (The bottom of the Heatsink)
Thermal paste is used to fill these voids. Helps to transfer the heat from the Processor to the Heatsink.
A Heatsink is usually a copper, or aluminum plate with fins on it. Copper or Aluminum transfers heat very well.
Air is drawn over the fins, and draws the heat away.
(Works on the same principle as a radiator for a home, or a vehicle)
With a laptop the plate is connected to a tube, which in turn is connected to a finned piece.
This website shows the Toshiba Satellite A135, being disassembled right down to just the motherboard.
I thought I would include this so you can see what I'm taking about in reference to removing, and replacing the thermal paste, and what the top of your processor looks like, plus the Cooling Tube/Heatsink Assembly,
This is Page 1.
At the very bottom of the page you will see in white -
Page 1::Page 2::Page 3::Page 4::Find another model
Left-click on Page 4.
Scroll down, and left-click on the photo to the right of Step 23.
The Cooling Tube/Heatsink Assembly is the gold colored part. Where you see 061224 upside down on that curved tube, is the Cooling Tube.
The square object under the 061224, is the plate that is right above the Processor.
Left-click on the photo to the right of Step 24.
This shows you the top of the Processor, with the Cooling Tube/Heatsink removed.
The Processor is marked CPU.
CPU stands for Central Processing Unit, or Processor for short.
What is hard to see is the actual top of the processor case itself. It is a small square that is right under the red letters CPU.
After the top of the Processor case is properly cleaned, a tiny pea sized dot of thermal paste is applied here.
Then the cleaned plate for the heatsink, is set down on the top of the processor case.
Other then that, they turned the screw on the left of the processor socket, (Circled in Red), removed the Processor, and replaced it.
(A replaced processor does require new thermal paste applied. Cost of thermal paste? About $7 USD. Enough to do 6 processors)

You will have to put a Windows DVD in and boot on that and do a "Repair" install, if that will not work, you will have to do a complete format and reinstall Windows.
But try the below first if you can.
1. Restart the computer.
2. Repeatedly tap the F8 key until you see the Advanced Boot Option Screen.
3. Select Repair Your Computerand hit Enter.
4. Select your country >> OK.
5. On the System Recovery Options Screen select Restore Application.
6. Follow the on-screen instructions.
8. When prompted, select on "Full Factory Recovery"
9. Select Next >> Yes.
10. After a couple of minutes the recovery will be completed. Check to see if your PC will perform a Factory reinstall from a "Recovery partition" usually accessed via CTRL F10, or just F10 or F12 Check your manual, as if this is available it will restore your PC to a "From the factory state"
BTW, your hard drive may be ruined you may need to get a new one. Then reinstall Windows from DVD.
