The XC0369 weather station when used in the Southern hemisphere has the solar cell used to charge the batteries facing away from the sun when aligned north.

if you can --put the solar panel horizontal so that it doesn't matter where the sun is
the solar panel works from ultraviolet rays and not direction so if you are doing what you are there is another problem with assembly

The BIOS is not reading the HDD

A bad/faulty lead can lead to a computer not recognizing a hard drive and any other connected devices
One bad lead can cause a computer lots of problems
replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA the ones that attach from your motherboard to your hard drive
hope this helps

Oc a nvidia geforce 5700 ultra need info


Do you want to overclock the 5700 ultra? Its a old card and the performance wont get much better, instead I would suggest upgrading the video card to a newer one or the whole computer.

The nvidia 7xxx series fits into a AGP slot I would recommend that, its alot better but upgrading the computer would be even better.

Let me know if you need anything else.
