Add my ECS board (from the Outpost deal ECS k7s5a I believe) to the list of failed boards. Mine suddenly wouldn't post after about 3 months of use and no overclocking. It seemed to be a CMOS error with one checksum error message but most times it wouldn't post and now won't post at all. I reset the CMOS by every method know, (removed CMOS battery and unpludgged power, jumper switch disconnect etc) without success. I think some of many of the ECS boards may be defective. Maybe the ECS outpost combo price was low for a reason.. I finally decided to rebuild the entire 'puter with the best quality components and hope for better days.
I spent the better part of a day on the attempted repair involving at least the following:
CMOS fixes to excess described above,
Tried to flash BIOS but can't as floppy drive isn't even "seen"
Verified power supply has correct voltages,
Verified hard drive will boot on another computer,
Replaced Video card,
Reseated most everything but processor (ram, jumpers,c cards etc),
So I'm off to spend some money on new parts as waranty is over.. Just be careful if you have this ECS board as it may have a tendency to serious acute failure.
Aside from this problem, Happy days to everyone!
