2 Short Beeps Your computer has memory problems. First check video. If video is working, you'll see an error message. If not, you have a parity error in your first 64K of memory. First check your SIMM's. Reseat them and reboot. If this doesn't do it, the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You'll need to consult your manual to see which bank is first. If all your memory tests good, you probably need to buy another motherboard. 3 Short Beeps Basically the same thing as 2 beeps. Follow that diagnosis above. 4 Short Beeps Basically the same thing as 2 beeps. Follow that diagnosis above. It could also be a bad timer
Make sure you do not have any devices plugged in to the computer like a USB flash drive or a MMC. Usually what you have to do about that is to drain the power of the computer. Turn it off, remove the battery, unplug the AC adapter and then press the power button for 5 secs. Turn it on using the AC adapter alone. if you still get the same message, You will have to physically open the back of your laptop and reseat the Hard drive. If it still wont correct the problem, restart you computer and either press f2 or delete to enter the BIOS page. check if the HDD is properly detected and try to reload the BIOS defaults. now if any of these wont work, call ACER and most probably your Hard Drive is bad.
I had something close to this problem with XP. I was trying to install and it would get to the screen where it was detecting hardware and just stay there for ever. I took out the hard drive and put it into another machine repartitioned and reformated. I put the hard drive back in and all was good.
BSOD is caused by hardware error or driver error. Disconnect all hardware except the basic. Motherboard, monitor, memory, hard drive. Unplug the wireless, cd/dvd drive.
Start the computer and see if the the BSOD returns. If not, one by one add components until you see the BSOD.
If you continue to see this screen without any hardware attached, then you most likely have an onboard component failing. (audio/video/memory failure)
Download and run the MS DART cd and check hardware starting with memory then hard drive. http://www.microsoft.com/windows/enterprise/products/mdop/dart.aspx
This should determine what device is failing, except video or audio.
if the laptop has a floppy drive get a bootable win 98 disk. insert disk first then turn on comp. run w/o cr rom support. at command prompt type "fdisk MBR" hit enter remove disk and reboot. if still bad insert win XP disk and do the second repair not the first one let it run its course. if not well you will have to reimage the comp
