If you merely loaded sotware on it you didn't reprogram it. ..... What country did you buy this notebook in? Your model is probably identical to an eMD525. Take a look at the pictures and specs, etc. here: http://support.gateway.com/emachine... If your computer is in that series, the software downloads are here: http://support.gateway.com/support/... "The Acer Group is a family of four brands -- Acer, Gateway, Packard Bell and eMachines." Did this computer have Vista on it and you installed XP from a regular CD? Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them. In your case, you might need to go the Intel web site to get the main chipset drivers - for a laptop or notebook, NOT a desktop system.
