My fan was making noise so I opened it up to clean it. After closing it, the laptop boots for only few seconds( black screen, only touchpad light is on, fan is on) but eventually, everything goes off after seconds. Local technicians have recommended a new motherboard but I want to know if there is any help. If not what type of motherboard dyu recommend. Don't know the laptop's exact name. It has switchable graphics(intel hd 3000 and ati radeon 7400m) , beats audio, fingerprint reader, 8 i7 cpu's, two memory cards, 15.6 inches.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
