Until this morning, when the laptop died. Totally refused to turn on, with the caps-lock light flashing 5 times in succession, a signal that the internet informs me means "motherboard fucked".
I phoned HP, who do out of warranty repairs, to be quoted £260. As it only cost me £400 this seems a tad silly. A part of me wishes I'd got the three year warranty with it. I'd never bothed with a desktop, but laptops don't have replaceable parts in the same way.
So it looks like I'll be buying a new PC in the near future. Not that we can really afford it. It's going to have to be a cheap one.
A quick google tells me that an Athlon 630x4 and an ATI 5670 are both at the right point on the price/performance graph for me. Anyone want to tell me different?
