Hi, I have got a problem with my HP PC.
5 red flashing lights one second apart and beeping sound when I switch it on.
How can I get it fixed as I have my course work on it?

That just happened to me on my d530 CMT after I was cleaning around it. So, I could not get it to stop. I unplugged it from the wall, slid the top off and vacuumed really good. It came back on and I am typing this. It seems OK. It was a little funny when I first started it up and that may have been from my messing with it before I opened it.
