HP freezes on startup and screen blinks

By chershaz ·
I have a HP Pavillion 720a, which is just 12 months old, I have had a new hard drive replaced, the ram has been changed over and new drivers added, yet I still have the same problem, of the computor freezing up and a black screen blinks at you when it starts up. As I am a novice, I would appreciate any help.

Could be a bad power source, or a faulty main board. I assume that it is still under warranty, take it back to where you bought it, and demand it be fixed or replaced.

If you are going to take it back, you might have to replace all the original components back in it. This might be smart for you to do anyway if the original HDD & RAM were faulty. (Keep the new stuff you bought for your replacement system or resell it if it is not compatiable).

Failure to replace the original hardware in the system may keep you from being able to return it or some sort of additonal fee.

GOOD LUCK!
