WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty

if its a 40 pin flat ribbon type it will be the first to fail

make sure all leads that are attached to your drives dvd\cd and floppy have secure connections and are not faulty

even something as small as a faulty electrical fan and its lead can cause you problems
computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error

Check your RAM.
The RAM is located in the middle of the motherboard.

There are tabs that you can push to release the RAM.
Remove it and put it back in place until the tabs pop out.

Loose RAM can cause your computer not to start properly where you want to see a video signal.
Remove the memory modules from their slots.
Take the opportunity to clean the slots on the motherboards and the memory module connectors.


Use compressed air to blow dust away and clean contacts with a soft cloth.
Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components.


Do not use solvent that may attract dust and never poke things like cotton buds in to slots, lightly rub alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r


Allow the pins to dry.
They will air dry in a matter of minutes.


If reseating the memory did not resolve the issue try swapping the location of the memory. Make sure your graphics card is securely seated with no dust built up or in the socket
if you remove your graphics check the socket to make sure its dust free

Restart your computer then reinstall it this should activate found new hardware wizard

Check the vga lead for secure dust free connection or try another vga lead.

EMachines eMD620 suddenly shutdown and not boot anymore


When this happened was the laptop overly hot? If the laptop's head got too high it could have shutdown to protect itself. It wouldn't boot until the heat had disparate. Sit you laptop aside for about 30 minutes and see if it will boot then. If it does you might want to check out a cool mat.

Jumpy splash screen


There are a few reasons why? One the video card is going on the mother board. A loose connection that requires professional attention to check or make sure that the cabling is correct, which requires taking the laptop apart where the power button is located near there as well. BIOS could be going bad or need an update. I would start with inspecting the cable going to the monitor first to make sure it is solid. The laptop I assume works great once it is booted up and running. If this is not the case and you still getting periodic splash screen jumping then it would be the video card. This is why it is a great idea to purchase a laptop cooling fan while in use. John

My Toshiba Tecra M5 won't boot. The power light flashes on and off, the fan starts but nothing is on the screen. How can I get it to boot?


Well, it sounds like you have a hardware problem. Start by removing the Ram and hard Drive from the machine and insert a boot disk. If your not getting the Tecra Splash screen when you press the power button, the screen that appears before the windows boot screen, you may have a bad Monitor or Burned background lamp or faulty BIOS install or upgrade. Any of which will give you this problem.

C500 Laptop won't come on power button just flashes


Have you tried attaching an external monitor when the LCD screen is disconnected from the motherboard? this connector is located under the keyboard strip – a piece of plastic just above the keyboard.
If it works, this way, then the video cable isn’t seated properly in the connector on the back of the screen. Plugging the video cable back in should fix the problem.
I don’t know how comfortable you are with taking apart laptops but I think that this information could be useful for you.

After RRoD fix, hangs at splash screen and no front lights


ya appliyng thermal past does little if
nothing for the problem your discribing.
did you heat up the G.P.U. and keep
the C.P.U.cool wth the fan till you got
two reds? if that the case there may
be more diconects under the G.P.U
It is fixable but you need specail equipent
that will compress both sides of
the chip as you heat it to around
320c that will fix problem boards like
yours 90% of the time

Dell inspiron 1501 push power button no screen or sounds


Have you hooked it up to an external monitor? If you can see windows booting up on the external monitor then u may have a bad lcd screen or inverter or video card? Still lots of questions to ask.

Sony Vaio laptop vgn-fs640-w problems


The motherboard controls the fan speed - and laptops often turn it off entirely when it is not needed. This sounds like a motherboard issue where an internal trace is broken and sometimes it makes contact, other times not. There's probably nothing you can do except replace the motherboard.
