laptop wont restart

December 16, 2011 at 12:16:32
Specs: Windows vista
the laptop will sometimes start up then works ok,but if it as to restart it just closes down ok but when it restarts it just gets to the bar moving from side to side and doesn't move on from there.
I striped it down and found a lot of fluff around the cpu fan. I have cleaned it but makes no difference

How did you clean it? Try blowing it out with canned air from a office supply.

Sounds like the laptop is running hot. Ironically laptops should NOT be used while setting in a lap. They need to be placed on a hard surface to allow proper air circulation. If you perform alot of stressful operations then you may benefit from a laptop cooler like shown in the link below.

Im wondering if the fan (even though it's working) isn't working hard enough, so not cooling the cpu so thats why it wont restart?

Laptop fans only run when needed. However, if it is gummed up and can't run the unit can overheat. What happens then is the processor automatically throttles (slows) down to prevent making more heat.

Do you notice the unit running really slow?

Try the above suggestions. You can also boot into the BIOS (setup) by using the keystroke indicated on the screen when first starting up. Then look for a screen in the BIOS that shows the system and CPU temperatures. Post back the numbers.

when i start the computer from cold and it starts up and the os completes, then it works fine, it doesn't slow down, but the fan does get a bit louder
I have checked the bios but there are no cpu temperature listing

Then download and install HWMonitor to monitor temperature in real time. The fact the fan speeds up in proof the CPU is getting hotter. Get HWMonitor from the link below.

Did you re-apply thermal compound? I have a Dell laptop with a phase change radiator. I apparently cracked the thermal epoxy between the cpu and the heat pipe while cleaning the fan. I had similar symptoms. Had to remove heat pipe and chip off epoxy and apply coat of arctic silver. Works fine now.

yes i did put the thermal compound on, thanks for the replys everyone i have also deleted the os because i thought it could be crupted files, but when i installed the the os when it needed to restart it wouldn't. So that was a bad choice!
When it trys to restart it just goes past the post then stops then trys to restart over and over again?

If you blow it out it should work fine then. You didn't state how you cleaned out the fuzz but IMO blowing is the only effective method.

the fluff was not on the fan but in the air vent, it was the fluff you get from a tumble dryer, that must of built up over time
whats IMO?

In My Opinion. Still get canned air and blow out everything you can reach.
