Laptop Shutting Down Without Warning

[FrozenPhoenix]

Hi, my name is Sean and my laptop has been having some troubling issues the last few weeks. Before I explain the problem, I'll give you the specs of my laptop. It is a Compaq Presario CQ61, with 3GB of RAM, 250GB HDD, 2.10GHz Processor, and runs Windows 7 Home Premium.

I'm going to give a lot of details so that it's easier for you guys to understand the issue
Ok so here's the problem. It all started a few months ago when I noticed while using my laptop one day that when I plugged it into the charger, the charging symbol that would normally show up on the battery symbol did not show up. It still charged normally, but I thought it was odd. Later that week, my laptop stopped charging as fast as it used to. I would plug it in and it would take twice as long to charge to full power than it normally would. Sometimes it wouldn't even charge at all, it would just stay at it's current power level. That didn't make much of a difference to me, so skip forward a few months.
About a week ago, I was using my laptop to listen to some music and suddenly without warning, it shut down. It shut down in a manner as if I had pulled the battery out. When i tried to turn it back on, the battery symbol flashed 3 times and turned on and worked like normal for the next couple of days.
3 days ago, the same thing happened again, but when I tried to turn it back on, I got a BSOD. Once the BSOD disappeared off the screen, it continued to start up and worked like normal again.
Last night, it shut down randomly again, and I got another BSOD. The difference this time is that after the BSOD disappeared off the screen, my laptop shut down while starting up. This happened 3 times (BSOD followed by a shutdown) until it FINALLY turned on. I got this message on the windows error reporting message box that showed up.

If someone could make sense of the problem and the BSOD information, it would help. If there is anything else I can add to the problem to help feel free to tell me

What happens when you run it with the battery removed and the AC adapter plugged in?

When was the last time you blew the dust out with a can of compressed air?

[FrozenPhoenix]

I have tried running the laptop without the battery and only the AC adapter, and got no power at all.

To be honest, I don't think I've ever blown the dust out of the inside of the laptop. I've had it for a little over a year, and about 6 months ago I had to have it fixed for an unrelated issue and they said they blew out the dust for me. Is there a specific way to do this without harming it?
