I've been pulling my hair for 3 hours over this problem, so I thought
I'd ask in here, and see if people have had a similar problem.

I have an oldish (bought 08/2001) Socket A motherboard (ASUS A7V133-C).
The chipset fan was starting to whine after collecting dust for 6 months
(since I last cleaned it up). As I've done several times, I unscrewed
the chipset fan, partly lifted the sticker in the middle, put a drop of
vaseline oil on the fan's axis, and used a vacuum cleaner to make the
fan spin for a while. I did the same to the CPU fan.

Is that stupid? Is there a better way to treat fans when they get dirty
and start whining?

Now, when I try to boot the system, all the fans start to spin for a few
seconds (it varies from 1 to 4), then everything shuts down (I hear
strange sounds in the PSU), and the POWER LED on the front panel blinks
steadily (about 1 second on, then 1 second off) as if the PC was in some
sort of deep sleep mode.

Any idea what this means?

After several hours testing different combinations, I noticed that I
could boot if I unplugged my hard disk drive (uh oh!). My HDD is an IBM
Deskstar 34GXP DPTA-372050.

I don't understand how cleaning the fans could have damaged the HDD.

NOTE: A few weeks ago, I thought the drive was experiencing the "click
of death" (I thought it was a 75GXP, don't know if 34GXP were affected).
I downloaded the S.M.A.R.T. diagnostic tool from Hitachi, and ran it for
several hours. It found no problem with the drive.


Another experiment: the PC boots if I plug the HDD's power connector,
but leave the data connector unplugged. Would this rule out a problem
with the HDD? Or can the disk send weird signals on the data path which
cause the PC to refuse to boot?

Could the power supply be giving out? Does HDD initialization draw a lot
of current? (I might not make any sense, I'm just writing whatever comes
through my mind.)
