While my last computer fried.
It was more likely to the lightning strike.
KT800(some similar chipset) board with my athlon 64 3200(chip lived)
mobo video HDD's and 1 stick of ram(others still worked? *shrug*)
Next time I'll definetely get a nice UPS with guarantee.
However I have had restarting issues before from poor power supplies.
Also a lot of places have poorly regulated power.
If you were to buy a pc from dell you'd probably buy a warranty. ( I know none of us would but one from dell I hope )
They run like $400.
$10 for a better psu is in your interest.
