Major Acer Laptop Problem

Hello,
last night I was browsing the internet like usual when suddenly my screen started to flicker. Then it went off. The power of the laptop was still on but windows itself had closed and was not still running (no sound, nothing)

So I restarted the laptop and now it won't boot at all. However It appears to start up, or at least try to. The hard drive read button will flash once then the caps lock/scroll locks buttons once together and then nothing else happens. Nothing else is shown on the laptop screen, not even the usual Acer boot menu and there are no beeps or anything like this.
After about 5 minutes of the laptop being on it restarts itself and tries to boot up again, but with the exact same problem.

Please help? Thanks
