My Mum’s Dell laptop is 3 months old.
When Windows update tried to install service pack 1, it died horribly. Every time we booted there was a “blue screen of death” (I have photos). Safe mode, repair mode, nothing worked. Ruined a day off.
Dell support were hopeless, the only concrete suggestion was to restore the PC to it’s original state. And they kept insulting my Mum for installing such haxor 3rd party software (such as Firefox) and peripherals (such as a USB mouse) that caused running Windows updates to kill it.
I downloaded the latest Ubuntu Linux (9.04). Booted from the live CD. Backed up the documents. Installed Ubuntu. Restored the documents.
The machine now runs much faster than Vista did.
