Hello. I have an Acer running Vista that refuses to boot. No beeps, no monitor, nothing. There is power to at least the fan and the DVD so I am supposing that the power supply is ok. It is only a year old. I have - removed and replaced the RAM and the battery. I have also tried the hard disc in another pc to realise that the operating system has been corrupted, although I can see the files on the disc. The hard disc did nto boot normally and i used a utility to view the files. Vista repair could nto repair itself so I am supposing at the very least it needs reinstallation. But back to the Acer. Since the graphics card and everthing else is on board, am I correct in assuming that the motherboard is dead? Thanks in anticipation.
