woops... watch out...

you found the problem, so work on it.
this could kill alot more than just your PC.....

If the electricity killed something you can get a refund of the damaged goods if you can proof it's the the suppliers fault.
No joke : different electrical appliances had a problem in my parents home. I measured the voltage and it fluctuated between 185 and 230 (where you pay and should get a constant 220). After the problem was "investigated" (boeha) by the electric(al ?) company, they got refunded a solar lamp (solarium bench - tan instrument ?).
You said KT7A ? I had an enormous amount of troubles with that mobo ... changed/swapped ALL HW-components ... NO GO. Then sold the board to Blackrabbit for a measly 25 EUR. It worked fine for him. Afterwards i read there could be a problem with the middle ATX screw ... if it was tightened too much the mobo would just stop working.

If failure rate is at your level the team members will back you up at M².

good idea Bosw8er.
Ive got a MSI KT7Turbo limited edition you can use (same chipset as the KT7A from abit).
just ask.
It works still great.

And one Duron 600 that does 1.1 Ghz without any problem.
And one Taisol HS (without 60mm fan)
And one 250W PSU.
And 128MB PC133 SDRAM.
And one Phoenix maxi gamer 16MB :o PCI VGA
And one 10MB 3com NIC

... no case tough

... just ask

a case or a PSU is no problem.
with some luck I got a Ti 500 back you can use also :)

Problem solved: The wallplug I was using had no grounding at all. I'm using another one now, and my hair doesn't smoke anymore when I touch the case.
btw, Abit's rma service for the max-series is great, within one to three days there should arrive a new mobo here!
thx for your offers but hopefully I can use my own rig; cpu, ram, graka etc are tested and still working
