My dell inspiron 15 3521 won't start and continously beeps after starting giving 2 beeps. After a 100 tries it starts by luck but then works fine even the dell diagnostics after startup shows everything is normal. But y won't it start? This happened once before aswell 3 months after i bought my laptop for around 2 weeks after which it resolved spontaneously. Now this problem is back. I tried removing and reinstalling the ram aswell but it was of no use either. Plz help.
