The room ambient temperature is less than 80 degrees F. All 6 internal
fans are working and the cpu temperature is less than 100. The box
temperature is less than 85. The Box currently contains 2 60 Gig Maxtor
drives in a RAID Mirror configuration used for all programs, a 160 Gig
Western Digital Drive for data, A DVD Writer and a DVD Reader, A 3.5
inch Floppy drive, the mother board (for the past year) is a Gigabyte 7
with onboard drivers for RAID, 10/100 ethernet, USB, Firewire, and
Audio. There is no accumulated dust, as I have used dry air to blow out
the dust about once a week. The computer is used primarily for Adobe
Photoshop, followed by web surfing and gaming. The area the computer
is in also has a large room fan blowing directly towards the computer
when it is in use.

The most recent failure, about 3 weeks ago was the DVD Writer. The
motor that spins the DVD failed.

The failed motherboard was a Soyo Dragon Ultra, and the caps around the
CPU literally blew their tops. This was last year in August. It
followed the original power supply that blew out in July almost 3 days
after the warranty period expired.

The voltage variation is minimal with the A/C on or off. The line voltage
does not appear to me at least to be your problem. Since these all happen
in summer, I'd ask about the ambient environment and cooling for the system.
Is it located in a room that is very dusty/dirty and/or gets hot in summer?
Is the unit in a corner, in a desk or some type of restricted airflow
cabinet? Do all system cooling fans work properly? Are the intake and
exhaust grills/filters clean and unobstructed? When was the last time you
opened up the unit and vacuumed out the dirt?Have you attempted to determine
the internal box temperature?
