As simple as; i turned off my laptop 2 nights ago as normal then when i turned it on again yesterday it was wiped, no history and started up like it was new. not even the wallpaper was there it asked to re register everything and loses memory each time its turned off. everything i had seems to be gone,
ive not a clue what happened.
Sounds like your CMOS, which is the well-hidden thing on your motherboard that keeps a small bit of power going to retain date and time information when the computer is shut off. If it loses its charge (due to defect or age) it will work fine as long as the computer is on, but after a few hours will lose all ability to maintain the most essential information. This will cause the computer to boot as if for the first time.
Check your time and date; also knowing your OS would help. But I suspect it's your CMOS, which can be replaced at any computer repair shop.

Boot your system to Safe Mode (press F8 repeatedly). Go to System Restore and choose a date when your system worked OK. Note: with System Restore, everything, including your documents and other files you saved on the hard drive, will roll back to that date.
I suggest going into the control panel/device manager and removing all the usb devices. Restart the computer and let it find the devices again. That might help. Also--have you tried the stick in another computer just to make sure it works?
There are two slots for memory on that laptop and it will take a maximum of 2GB of RAM. The memory type is
1.8-V SODIMM DDR-2. The cover ont he bottom if the laptop is easy to access and add more memory.
How old is the battery? The battery is considered a consumable product. It really has to be replaced usually after a year or so. You may try updating your computer's bios software though to see if it will correct it. Updating this software is a bit risky and if not done correctly may further damage your system's motherboard.

Click this to start the update. It can only be run though if the battery still has 30% charge. If you get an error during the update, you must replace the battery.
