On start it shows blue blank screen and nothing is displayed

A factory reset might not fix this, but here you go.

1. Make sure you are plugged into A/C.. Your battery could be running low.
2. Make sure there is nothing blocking the heat vents. This symptom is typical for overheating processors.

You best bet is to pull the hard drive and attach it to another computer. This will allow you to copy the infomation you are worried about to another sorce. Most computer retailers that offer services will have a back up service and can do this for you. The average cost in my area for a back is $100.

Once you have the computer repaired, make sure you back things up. If you are worried about loosing something back it up twice. External hard drives are reasonably priced, and most computer have some kind of optical burner.

Hope this helps

Turn off computer. Now turn it on, and as it is starting hold down the F8 key. you will hear a beep and ket it go. A set of options will come up and choose Safe Mode with Networking. if it manages to get to windows you are fine.
If not, hit fn key + a key with a smzll monitor (usually one of the F keys at the top, like F5 or F6). It might have been put on display mode and woukd onky show if connected to a projector, tv, or external monitor.

Hit FN at boot then let me know what it does

srin is damaged.

This doesn't sound like a hibernation problem, it sounds to be much deep, motherboard deeper, but let's rule out the hibernation. Unplug the laptop, take out the battery, this will completely shut the machine down. Then put every thing back and restart. If it starts, then disable the hibernation mode in the display properties, screen saver tab, under the button that reads power. If it doesn't start, then the problem is with the motherboard or one of it's components. Take it in for a professional diagnostic, they will be able to tell you exactly where the problem is and if it's a replaceable component.

From what you've described, it sounds like you are clicking the Standby button, instead of the actual shutdown option. On the Start button, you will see (from left to right); Left: Start Search Middle: Standby Middle: Lock Right: Arrow Clicking the arrow will show you the Shutdown menu option; http://blogs.chron.com/techblog/archives/shutdown.jpg
