Hi there i have a toshiba satelite a30 which was working fine until recently and would shut down after 5 mins, so i ripped it appart, cleaned all the *!@: and stoor out it, changed the thermal paste, done a clean reformat and it was fine. Coming home today i turn it on to find an error message blue screen and i cannot boot. Now whilst its instal.ing windows xp again its beeping, every 30 seconds it beeps, the charger is plugged in and im pretty sure the battery is fully charged, taking the charger out and it still beeps. Will update when windows is installed again, if it gets that far, but any sugestions anyway.
