Windows 7 is crashed

I have a pc, I was streaming online when suddenly windows 7 tell me there is a problem with windows, save all your document, in a minute windows will shut down....
it did shut down and when I booted my pc...it would only show me my motherboard logo and then a black screen with only a ''_'' blinking on the top left....I cannot do anything more

later I looked up for solution and since I could not access bios, I removed the battery and did a hard reset for 30 sec, replaced the battery....it just became worst....when I start the pc, the screen is completely black ( the light of my monitor turn orange as if the pc was in sleep)

help me plz

my motherboard is MSI H61M-P35
 
"it would only show me my motherboard logo and then a black screen with only a ''_'' blinking on the top left....I cannot do anything more... The hard drive is probably bad
