I think it's counterproductive to apply solder first, which would serve
to keep the chip off the board. I absolutely agree with the liquid flux
idea, then a drop of solder on the iron and skate it down each edge.

http://cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=360351163467&ssPageName=STRK:MESINDXX:IT

maybe this chip is not the same as that of my laptop
I do not know if my laptop or yours could be OK.

Another question.
The difference between this
http://cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=110658426046&ssPageName=STRK:MESINDXX:IT
and this,
http://cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=380296779947&ssPageName=STRK:MESINDXX:IT

what is?

Thanks

I've put the computer together which I mentioned in my previous "outside
the case" post, and I'm am having a bit of difficulty, though I doubt
it's related to the no-case part. I know this isn't really a computer
forum, but if any of the very knowledgeable people here have any
insights into the following, I'd sure appreciate hearing them.

The components of the new build are as follows:

-GIGABYTE GA-X58A-UD3R LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel
Motherboard

-Intel Core i7-950 Bloomfield 3.06GHz LGA 1366 130W Quad-Core Processor
BX80601950

-HITACHI Deskstar 5K3000 HDS5C3020ALA632 (0F12117) 2TB SATA 6.0Gb/s 3.5"
Internal Hard Drive -Bare Drive

-CORSAIR XMS3 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)
Triple Channel Kit Desktop Memory Model TR3X6G1333C9

-Microsoft Windows 7 Home Premium 64-bit 1-Pack for System Builders - OEM

-Thermaltake Black Widow PSU W0319RU 850W ATX 12V v2.3, EPS 12V v2.91
CrossFire Certified 80 PLUS BRONZE

-Older Powercolor X800 GTO vid card

I have initially set up the bits on a table, outside of the case (so I
can still use the PC which is now occupying the case until all is well
with the new bits). Loading went fine, got online & began loading
software, when the PC locked up. In the ~6 hours I've been playing with
this, it has not run longer than about 20 minutes without locking up,
sometimes only 5 or 10 minutes. It seems fine, then just locks. No
mouse, no keyboard, no ctrl/alt/del function, I have to do a reset to
get it going again. I've pulled the HDD & re-installed the OS on a spare
160 gig IDE drive I have, same behavior, so it's not the HDD. What
components are the most likely culprits here? Any suggestions anyone
might have on this situation would be greatly appreciated!

I should add that I installed about 55 updates from MS to the Win 7
installation (all available), after which it still locked.

Haven't had an OS lock up since Windows ME. I'm already missing XP! ;-(

Just guess "Heat related" ! Make sure that the heatsink/fan assembly is
fitted properly and recheck BIOS settings for temperature behaviour.

I've never had 7 freeze requiring pulling the plug. Check the event
viewer / system for events marked by a red X. Might get a clue.

If your BIOS has a hardware monitor, check temperatures and voltages.

Remove the video card and use the onboard video.

Just a few things I would try. I'm running an AMD 955 PhenomII quad core
overclocked from 3.2 to 4 ghz on an Asus M4A7T-E, similar RAM and have no
problems whatsover.

I have had constant blue screen problems using windows 7 64 and an I7
computer though the windows 7 32 works fine. I'm to the point where
I'm about to install 32 bit software and take a performance hit. (This
is on a Dell laptop.) Chuck

There was a 'sort-of' recall on i7 chips a while back. Google i7 SATA
bug.

I think that was the Q57 chipset, not the processor, though.

Odds are it is not related to 64 bit Win7. Thousands have been
running it without the level of problems you are seeing.

There are various flavors of 'Ultimate boot CD' that allow you to boot
from CD and run diagnostics independent of your OS. Try one of those.

Check bios settings, both for temperature and for performance. I'm
running Win7-64 on a Gigabyte motherboard and adopted the attitude
that it's better to run a little slower and avoid lockups. I haven't
had any problems that couldn't be traced to the unit between the
keyboard and the chair.

I've seen temperature mentioned several times in this thread, and that would
be my first guess. You might try aiming a desk fan directly at the
motherboard/cpu prior to powering up and see if the forced air makes any
difference. Easy to try, and would probably eliminate overheating as the
problem if it doesn't make any difference.

This may be a COOLING problem. the cases are designed to give airflow where
needed,and I've read of PCs that had merely left their covers off
overheating. the uP heatsink and fan may be designed to work best when the
MB is vertical,not horizontal.
My second guess would be grounding of the MB;in other products I've
encountered where all the screws had to be connecting the PCB to the case
for proper grounding,that some sections of groundplane were not connected
to the others on the PCB,the case did that It also may be connected to
noise shielding.

BTW,I'm still running W98SE,on a 900Mhz Athlon.

Thanks for all the helpful replies. I have a utility called Speccy that
monitors temps, yesterday the CPU was showing 39C (104F), which I
believe is low. Speccy also shows voltages, on that issue, which ones
should I be looking at, and what should the be? I also run it on my
current core 2 Conroe, it shows the following for this setup:

CPU core - 1.168
Memory controller - 1.840
+3.3V - 3.328
+5V - 4.992
+12 - 10.371
VIN5 - 1.616
VIN6 - 1.488

Which of these would be most critical to the freeze situation? This is
a different PC/PSU, and this setup has run fine for 5 years. Not sure
why the 12V reading is ~1.6 volts low. I was just directly measuring
some voltages on various cables on that PSU while the PC ran, the 12V
ones were measuring 12.12V. Any thoughts appreciated.

I hope it's not the Win 7, but I have loaded XP on an available drive &
will see how the PC runs that.

Thanks all again for the terrific input!

Is this the recall in question: http://techreport.com/discussions.x/20326 ?

The page says in part:

The problem that's caused Intel to initiate a billion-dollar chipset
recall affects the SATA ports on all 6-series chipsets, including the
H67 and P67 chipsets most prominently used in consumer products. All of
these chipsets are collectively referred to as "Cougar Point" inside of
Intel. Because there are no third-party chipsets compatible with Sandy
Bridge processors, all Sandy Bridge-based systems are potentially
affected, including desktops, laptops, and DIY motherboards.

I'm assuming that since my MOBO is a GIGABYTE GA-X58A-UD3R LGA 1366
Intel X58 SATA 6Gb/s USB 3.0 ATX, which (apparently) uses the X58
chipset, not the H67 or the P67, that this is not an issue for me, correct?

Also, the flaw apparently does not affect the 6Gbps SATA ports, which is
all I have used so far (New HDD onto which I loaded Win 7 is 6Gbps)

Of course, these things have a tendency to GROW over time. 1st it's
only THIS line of products, then, oh-ohh, it's also THIS line too, and
maybe THESE OTHERS. Companies tend to 'fess up slowly in such situations...

Don't know if the mobo has a PATA controller but try installing
7 on a PATA drive.

When you said you wanted to run outside the case I thought you had
some inexpensive old parts. You have enough money for that good stuff
and you won't spring for another case / power supply? Makes no sense
to me.

Does the BIOS have any voltage and temperature display. It would be

I assume that the directly measured voltage was with a multimeter !
12.12v is fine. Interesting to find out why Speccy reads it low...
Or is this two different PSU ?

Thanks.

That's got me scratching my head. Why should the battery type have any
effect whatsoever on whether the charger powers the motor?

Does the motor run when no battery is installed?

My Norelco when completely discharged will run very slow at first when on
AC. This lasts only for a few seconds.

Probably because the discharged battery is pulling down the supply. When the
voltage pops back up, there's enough current to run the motor.

It is called "the innate perversity of inanimate matter".
There was an article on it published MANY years ago in CQ magzine.

It have some ways to use ipoim to do things around the ham shack.
1) in order to prevent stretching from detuning your antenna, cut the wire
short to allow for stretch.
2) to fix a complex electronic device:
a) go through the parts list and contact all the parts suppliers. You
will find one or two parts that can not be found anywhere; it is one of
those.
b) examine the layout and locate the part that is most difficult to
remove and replace. You just found your defective component.

I don't remember the rest of the article but it has proven to be quite
useful to me, over the years. :)

Since this is at least the fourth (?) time you have asked
[Jan 24th, Jan 26th, Feb 7th, and "now"] and (apparently)
haven't received a response that you are happy with, why
don't you contact Sharp directly?

Or, if your time is worth ANYTHING, consider replacing the set
with something newer/better/cheaper -- one that *doesn't*
"blink" when you turn it on/off!

Decades ago, I had two stereo receivers/amps that my EE uncle tried to fix by
tapping every capacitor until he gave up. I also had a sim problem once with
a computer that went blank in RS232 tty output but I fixed it only when the
manufacturer told me exactly which capacitor to replace (in a twist, the only
way I could actually get a single such capacitor was to request an
"engineering sample"). I am a Ch E with two mandatory semesters of EE and two
introverted EE uncles who never really explained what they were doing while I
was growing up. So I probably know more than I have confidence in. I am
looking at this $80 TV that has worked for about 18 months and am trying to
figure if it is worth fixing. I suspect if I throw it out, my uncle will pull
out of the trash and put it in his shop but never quite fix it anyway.
