black screen after welcome

[winnie]

Hello everybody
please help
well, I am getting a black screen after the welcome screen appears with just a cursor on it which I can move.
this problem started after my laptop's battery got fully drained. I am using Lenovo ThinkPad, and I have windows 7 os. Please provide a solution as soon as possible as I have some serious work pending which always is the case when my laptop gets into never-ending trouble.

Winnie hello ansd welcome mate first some system specs please http://www.sevenforums.com/tutorials/180324-system-info-see-your-system-specs.html post if you cannot send pics

Plus please run this

Using HW Info

PART A:

You can test the volts onthe PSU with HW Info HWiNFO,HWiNFO32/64 - Download <download the right bit version and close the right hand window select Sensorsand scroll down to the power section where you will see what the volts aredoing see my pic. In my pic the section (Nuvoton)with VBATT is a dead give away you are in the section for the rail voltages.There are other section titles and one that pops up often is ITE

Now the voltage on thedifferent rails have to be within 5% =+/- of what is required or the machinewill not work properly if at all.

See this for the railvoltage info

http://www.tomshardware.com/reviews/power-supply-specifications-atx-reference,3061.html (Section 2.)

The original right handwindow shows the machine running and is handy for that but for looking at thecomponents in some detail close it and use the main left hand side panel

FOR OTHER COMPONENTS

PART B:

Open each small squarewith + in it on the section the components are in and then click on theindividual component/s (it willhighlight in blue) - in the right hand side will appear all sorts of detailsincluding brands speeds and other essential info that particular device. Seepic for example.
Again if you cannot send pics I would like to know the battery cell volts and capacities see pic of my machine
