Firstly check the monitor, if you get 8 beeps as it is starting up, this points to graphics problems. Trying another monitor. If the problem remains, swap the graphics card or use the onboard graphics card.
If this fails and, more importantly, you are not getting any beeps (single beep would indicate your CPU is ok), the problem is likely to lie with the motherboard.
To help you further, please repost with the number of beeps if any, you get as it tries to boot up

    Right. The fact that you are getting no beeps indicates that there is a fault on the board or with the CPU. You can test this by carefully feeling the side of the heatsink , if it feels warm, then the cpu is probably working, although substituting it with another one and fresh heatsink paste is the way to tell.

    If it is cold to the touch after several minutes of running, then the CPU is probably dead

    If the heatsink is warm, the motherboard is probably faulty, visually inspect the board, looking closely at the capacitors and if any are bulging / exuding a brownish crust from the top, then this is most likely the cause and a new motherboard will be reqyuired

    Thank you very much for the advice, I am an absolute novice but at least I now know where to start etc. A new motherboard and fitting sounds like it may be costlly but I can at least now look in that direction.

Acer won't start

Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

Acer Aspire 5732Z won't turn on - the light comes on for a few seconds and then turns off - whilst the light is on the disk drive will open - the screen doesn't show anything

Could be bad ram,hard drive or possibly a bad display panel or video card.Try using different ram and removing the hard drive then try it.Also,connect it to an external display and see if it shows video or not.If after trying these things it still isn't showing let me know and i'll try to help more.
