well if no post many things -- would ram or could be GPU chip -- have you tried cleaning it first?

If all those done - then you need to take it shop and check usually GPU problem they will reheat and resolder the GPU chip which will only last around 2-3 months depending on your usage and charge you like RM200 or RM250 depending.

SO i suggest if it an old laptop junk it and get a new 1 . If its fairly new like 2-3 year old then give it try a shop near you.
