So I posted here when I had a cooling issue on my HP Pavilion DV5z 1000 and it starting working perfectly after I fixed it. Then I kept experiencing a problem when I boot up and it would randomly not start due to a black screen. To fix it, I would pull out the charger, take out the battery and hold down the power button for about 30-60 seconds or so.
After that, I had another problem where I booted up and I would only get 2 blinks on the num lock/caps lock LED. I found out that the blink code was CPU not functional. I replaced the CPU and a blue screen came up after I installed it which had an error that said something about memory. So I took out 1GB of RAM from one of the slots and it started working. I used the notebook with only 1GB of ram while waiting for the other 1GB to come in since I ordered another one.
I received the other 1GB of RAM today. But before I could put it in, I encountered a problem when I booted the notebook. After powering it on, I get a blank screen but all the LED's on the keyboard are lighting up regularly. The caps lock/num lock LED's are blinking nonstop. I wondered if it was a code but it can't be because it's blinking constantly. Then, I powered it down and installed the other 1GB of RAM just to see if it work magically work, but it did not.
It's one problem after another with this notebook and I think it's time to purchase another notebook that isn't HP. Any help is greatly appreciated. Here is a video of what I am experiencing:
