I have a Dell Latitude CPX with 128mb of RAM.When I turn it on,the screen is complety blank,and the laptop turns on for 5 seconds,then off again.Is this a motherboard,RAM,or power supply problem,or is it something else?

General rule of thumb (though there are exceptions to this rule):

If it beeps at you AND stays on, it's either memory or graphics.
If it doesn't beep at you AND stays on, it's either motherboard or processor.
If it doesn't beep at you AND doesn't stay on, it's usually processor or PSU.
If it beeps at you AND then switches off, it's usually processor.

First thing to do is try another power supply. IF you can find one that works with that laptop as those usually have their own non standard units.

When this first happened,All I had to do was wait 15 seconds,and it would turn on again and work fine.After a while,it took longer and longer until I had to remove and reinsert the RAM.Now,nothing I do helps.Is that an exception?

john000...

Do you hear a beep during the boot sequence? Have you tried new RAM?

No beep,and i have a confession to make:I am only 13,and I got this for a birthday present,so I can't tell my mom.Which means I am so hosed.I learned a lesson though:Get a PDA.They are far more diffucult to fix than desktops,but they are also far more stable (at least thats true for Palm OS.)

aznjockboiX...you really should start you own topic

As long as you're here, please download Speed Fan, install it, and run it to monitor voltages and temperatures. Watch the Temp 1 temps at startup and after the machine has run a while then post them here for me.
