One most common problem is Toshiba laptop suddenly shuts down by itself without any warning. Sometimes it works fine for hours, sometimes it shuts down in 10-15 minutes.” This complaint hear over and over again. now the major problem OVERHEATING!
This is one of the most common problems with Toshiba laptops we deal with.
Indications of laptop overheating problem:

2. The CPU fans become more noisy and working all the time at maximum rotation speed.
3. laptop shuts down automatically without warning. Initially shut down after 1-2 hours andthen every 5-10 minutes of operation.
4. The laptop working fine in idle condition but it shut down when you use high memary application like DVD player, image editing software.

Solution:
Note:-If your laptop is under warranty then I advice to contect your local service center.
1)First you need to clean laptop with canned air, air compressor or vaccum to suck dust out. In majority of laptop you can access through the opening on the bottom or on the sides. But in some laptop like Toshiba satellite A70/A75 you have to open laptop case to access heat sink.
2) check the CPU heatsink is properly attached with processor. I also recommend to apply new thermal grease (between processor and heatsink) for better heat conductivity
1. If your cpu fan make unsual sound while it spins(grinding sound) It is adviceble to replace your fan.
2. Clean the fan and the heatsink with compressed air.
3. Also check the RAM and if require then upgrade it. Your RAM size always more then optimum recommended by operating system.
