Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error

hope this helps

Laptopscreen not coming on lights and fan ok


When it is running if you hold a light up to the screen, can you see anything on the screen? What about if you connect another monitor to the computer does that work?
If you see something on the screen using a light, you have a bad inverter or back light.
If you see nothing on the screen and nothing on an external monitor, you have a bad motherboard.
If you see something on an external monitor but nothing on the laptop then you have a bad cable or display on the laptop.

Solution 1) Set the system cooling policy to "active"
Windows has two approaches to fan control - "active" or "passive". The default option is passive, but if you switch it to active instead then the fan will turn on more frequently. You can do this by following these steps:
  1. Left click the battery icon in the bottom-right corner of the screen (See image)
  2. Left click More power options (See image)
  3. Click Change plan settings next to the Balanced power settings (See image)
  4. Click Change advanced power settings (See image)
  5. Click the + next to Processor Power Management (See image)
  6. Click the + next to System Cooling Policy (See image)
  7. Change Passive to Active for both Plugged in and On battery (See image)
  8. Do the same for any other modes you use, such as power saving mode
  9. Restart the computer

Solution 2) Keep Toshiba PC Health Monitor open
Some of the comments below sing the praises of PC Health Monitor. Apparently, the laptop fan will work harder when PC Health Monitor is open.
PC Health Monitor is already preinstalled on Toshiba computers. To open the program, just press the Windows key to open the Start menu, start typing "PC Health Monitor", and the program should appear in the search results. Click on it to open it.

Fan continues running after turning off ignition


HI. This will, generally, be the result of the cooling fan switch.

The cooling fan switch on most electric fans monitors coolant temperature signals from the engine control computer. When the engine is cool, the switch opens to keep the fan from spinning. When the engine is warm, the switch closes, thus, turning the fan on for cooling.

I would advise to Inspect the cooling fans(thermal switch),wires and connections. Cooling fan switch problems are often caused by faulty wiring or loose or corroded connections rather than the failure of the switch itself. If the wires or connections are bad, replace them. If you think the switch is defective, it should be tested.

The electric fan cooling switch, or thermal switch, can be tested by placing the element in a bucket of water. Heat the water to approximately 207°-216°F (97°-102°C) and connect the switch leads to an ohmmeter(make sure to keep the switch leads out of the water). The switch should have no continuity until the temperature reaches this level. Let the water cool off below 207°F (97°C) and the switch should lose continuity. If the switch has no continuity at any temperature, replace it.

NOTE_The thermal switch is located on the top of the radiator, usually on the passenger side.

Computor cutting out.....Remedy ??


As per your description, I understand that the issue is with overheating of the Notebook because of which it is turning off after running for some time.
First of all, Notebooks are not meant for heavy computing where they are designed for computing on the move and they cannot handle all the tasks we generally use in Desktop computers.
Coming to the issue, there will be some settings in the BIOS where the Notebook will be turned off when it reaches or exceeds certain temperature.
If the computer is allowed to run even at this temperatures, the Processor and Motherboard will burn causing serious damage to the computer.
First of all, check that the Cooling fan of the Notebook is free from dust so that it can spin at required speed and blow the enough air to maintain the temperature of the processor.
Additionally, see that the cooling fan vent of the Notebook from where hot air is blown away is dust free since if is blocked hot air will not go away and it will be circulating inside the Notebook making the notebook hotter and situaions will turn worst.
Blow the Cooling fan at the bottom of the Notebook and the cooling fan vent at the rear of the Noteook using Air Blower so that the dust which might be blocking them will be removed and there will be better cooling available.
Additionally, see that there is enouth room available at the bottom of the Notebook for enough ventilation.
You can also try using notebook cooling solutions like Cooling Fans which will be placed at the bottom of the Notebook and having two fans. These devices will be connected to the USB Port of the Notebook for power and blowing air to cool Notebooks.
Hope this helps...

Black screen not booting


check both your power and video connections to the monitor, sounds more like a monitor power issue.
if the connections appear ok, but screen still blank, try connecting a known good working monitor from somewhere else and see if it works with your pc, if it does, your original monitor is faulty, if it doesn't, you have a pc video issue.
