Good day everyone, 

I had acer aspire V3-571g and it was working perfectly good like for 9 months till now... When I power up computer, fans are turning on, black screen appers, hdd light is blinking and it stays black screen like for 10 minutes and nothing happens.I try it several times to power on and wait. After a few unsucsesfull tries, I repeat procedure and waiting again. And again I power on now, waited for a 2-3 mins and it boot ups normally. What could it be, someone had the same thing? Do I need to install new bios, format my system, or I should bring it to warranty service?

Also I tried to change ram memory slots , and remove battery and ac adapter unplugged press power button for minute, nothing change. As I mention sometimes I can boot up and it works perfectly, but usually after power on again black screen appears. Anyone has the same? I read that it could be bad caps, but still hope someone has same problem and fixed by themselves.
