Hi to all!
I have a strange problem with my Dell Inspiron 15 3537 running on a Windows 7 Ultimate 64 bit os.
One day I shutted it down via the regular way:start>shut down and after that when I tried to start it and it wouldn't boot.It showed me black screen and only the power light was on,i tried to start it a few times again but it shutted down or showed black screen,only the power light on and fans working.

I somehow managed to boot it and made a format and reinstalled the win thinking that the problem is caused by a virus.It worked well for a few hours then I decided to shut it down,again via the start >shut down and when I tried to start it later the same problem again!Then I somehow managed to start it but this time I got bsod:error stop 0x0000001E and it shutted down for 2 or 3 times.Then I connected it to a LG LCD TV via HDMI and it booted without problem!

I ran dell hardware diagnostics tests from the dell support site which lasted for 8 hours.The laptop worked fine and it passed all the hardware tests.After that I ran dell hardware diagnostics tests from the bios and the results were ok!The hardware passed all of the tests.

Finally I did a startup repair with the Win 7 installation dvd and the repair showed me this : The following startup option will be repaired name: Windows boot manager and etc. and :The following startup options will be added:Windows recovery enviroment etc. After that repair I decided to shut down the laptop via the same way:start>shut down, and when I tried to start it the same problem!Black screen with only power light on and sound of working fans or shutting down for a several time.

What should I do know?Please help me!I want to repair it myself without giving it to a service!Any help would be appreciated! Thanks in advance!Best regards!
p.s I do apologize for my bad English

I discovered something new ! The laptop turns on and boots after I make a hard reset (pressing and holding the power button for 60 seconds,before I connect it to the laptop adapter or put the battery on) ! It doesn't need the LG tv!
What do you think this means to be?
