Hi Ali. Are there any messages displayed on screen? If the memory has not been installed correctly, there will be an error from the BIOS and Windows will not boot. All the best, Ibrahim.

However, the netbook does not turn on. I changed the ram back to the original 1gb module still the same. The hard drive starts spinning but nothing happens. Does anyone have any idea what went wrong? Is there a reset button or something I can reset the unit? Thank you Ali
