This was a good one and I'm unable to fix or find out why but my main guess is that power got dirty to wreck 2 PC's in less than 6 months, it may have been my 16-yr-old UPS but can't be sure.
When did you last change the batteries, do you regularly test it?
If it has SLA batteries, change them every 3 years maximum.
Laptop is best solution, but I just had HD die on my Home Laptop, Win7, I just bought a new battery and keyboard for it, bugger.
