Solved! Dell Inspiron 1545 white screen

[Desire1503]

Hello everyone.
I had a Dell Inspiron 1545 where the motherboard was faulty, so I ordered one from eBay. Today it arrived, but when I put it in the laptop, the laptop starts, shows the Dell logo and then I get a white screen and it shuts off.. when I try to start it, the fan is spinning, I can hear the hdd working, but it keeps turning off after maximum 5 seconds.. I tried to unplug the LED cable from display but it does the same thing, I unplugged everything, what is strange is when I unplugged the ram, I get two beeps and then it shuts down. What can I do? What can be the problem?

could be a ram problem could be cpu over heating

I sorted it out, seems like it was because of the overheating, so I cleaned the fan and put new thermal paste and it's ok now.

if you need to clean it more use alcohol or a quick drying non conductive non corrosive cleaning agent with a static friendly cloth or cleaning wipe
