Never screw or un screw or even try to open up computer and work while the power is ON.
If everything is working fine on your system then I suggest not to worry. But if your video is completly gone we need to diagnose the video card (as I assume you have installed the fan and heat sink over video card??)
Hope that helped!

Heatsink/Fan Combo screws down to the motherboard.
4 screws. Each have a spring on them, so you do not over-tighten.

HOWEVER, tighten in a criss-cross fashion, and Evenly.

Bottom of the finned Heatsink, MUST sit FLAT; on the Processor, when reinstalled.

Need guidance? Post back in a Comment, and I'll step by step you through it.

Ignore if you are aware;

The Top of a Processor, and the Bottom of the finned Heatsink; are not perfectly flat.
A magnified view would detail, 'Ridges, Valleys, and Pitholes'.

When the two parts are mated together, these imperfections then create Air Pockets.
Air in this case is an Insulator, Not a Conductor.

Thermal Paste fills these imperfections, and is an Excellent conductor of heat.

[THOROUGHLY clean the top of the Processor, and bottom of the Heatsink.
There is a Proper method ]

The microwave does't make any noise ,,,but the count down on clock is working ...light is working but no fan ...or huming noise ...what could it be


HELLO.

The likely thing to be is that the microwave fan is faulty.the solution is to replace the fan.

Needed instrument:Phillips-head screwdriver.

Instructions on how to replace the fan is detailed given below.


    • 1. Unplug the microwave from the wall outlet to prevent an electrical shock while
    • working on the microwave oven.

    • 2 .Remove the screws holding the fan shroud to the top of the microwave oven. Using a Phillips-head screwdriver, turn the screws counterclockwise to back them out of the panel. Set the screws in a safe place so they will be available for installing the new fan.

    • 3.Slide the fan shroud--also referred to as a damper plate--forward, toward the front of the microwave, to remove it. Set the shroud to the side.

    • 4. Lift the fan assembly out of the microwave. An electrical cable and plug is accessible once the fan assembly is out of the way.

    • 5. Unplug the electrical connector from the fan and fully remove the fan assembly.

    • 6. Set the new fan assembly close to the top of the microwave to facilitate plugging the new fan into the microwave's connector. Plug in the fan assembly.

    • 7. Position the new fan in the same orientation as the old fan's before its removal. Lower the fan assembly into position.

    • 8. Slide the fan shroud in place and install the screws to secure the shroud.

    • 9. Tighten the screws with the Phillips-head screwdriver by turning the clockwise.

    • 10. Plug the microwave oven into the wall outlet and test the new fan installation.
Thanks

My new toliet seat dosent seem to screw on properly its all wobblerly its going from side to side


You probably just need to tighten mounting screws. Most screws are covered by a cap or cover that snaps into place. You should be able to unsnap the cover with a small blade screwdriver or knife point. Use a wide blade screwdriver on the slotted head screw on top to tighten while holding retaining nuts on the underside of toilet. Some of the screws and nuts are plastic so you should be able to hold the nuts by hand while using screwdriver to tighten screws. If you can't hold nuts by hand use pliers. Some use brass screws and nuts so use proper size wrench to hold nut. Hope this helps you. Thanks

My computer will not turn on at all after changing out my fan. I made sure everything was connected and when I rey to turn it on, I get nothing.


Okay, let's review, and let me ask some questions.

A) Did you follow Anti-Static Precautions? Used an ESD wrist strap, and connected the alligator clip to a good ground source?

B) Did you reconnect the Power Button Board?

C) Fan/Heatsink Assembly;
1) Did you reconnect the fan cable to the motherboard?

2) Did you scrape the top of the Processor clean, and the bottom of the heatsink plate on the cooling tube, and apply fresh, new thermal paste properly?

3) Did you tighten the heatsink plate screws in a criss-cross fashion, and did not over-tighten?

D) Did youi reconnect the RTC battery cable back to the motherboard? (RTC = Real Time Clock.
RTC Battery, another name for CMOS battery) You did disconnect the RTC battery, correct?

E) Reconnected the Power Connector Cable?

We'll start from here.

Koliki je broj obrtaja RPM ventilatora A38001-001; kakve lezajeve ima; kako se odrzava (cime se podmazuje) i koliki mu je ukupan vek eksploatacije u casovima rada hours? Thank You for Your`s Assistance,...


No, that fan is cookin'! > Spinning too fast.

The Sanyo A38001-001 from Intel, is only designed to spin in those RPM's when the Processor is REALLY Hot!

Usual RPM's are around 1750 to 1850.

A) Did you just buy and install this Heatsink/Fan combo?

1) If so, did you thoroughly clean the top of the Processor's case?
Used a scraping implement like a plastic credit card to scrape off the old Thermal Paste, and then used Q-tips dipped in Isopropy Alcohol?

[ Also know as Rubbing alcohol. 91% is best, but 70% will do in a pinch. Make sure it's dry afterward though. {91 percent alcohol, 9 percent Water, or 70 percent alcohol and 30 percent Water)

The Q-tips dipped in alcohol will wipe up the gooey mess of thermal paste. Usually takes quite a few Q-tips.

CAUTION!!
Isopropyl Alcohol is EXTREMELY FLAMMABLE!

Use in a well ventilated area with No sparks or flames present.

2) You did apply Thermal Paste, and correctly?
One small drop about the size of a large pea, in the middle of the top of the Processor's case.

Then set the Heatsink/Fan combo on top of the Processor, and tighten the screws down in a Criss-cross fashion

3) Tighten one screw down one turn. Go to the Opposite Corner, tighten that screw down one turn.
Skip over and tighten the other two screws down one turn as detailed above. You are tightening in an X pattern.

Make SURE the Heatsink's bottom is flat and level on top of the Processor's case.
If it is tilted even slightly, the heat transference won't be worth writing home to Mom about.
The Processor will overheat, and the fan will spin at high RPM's.

4) Is the Fan cable (Wires) plugged into the motherboard tightly? Plugged into the correct fan connector on the motherboard? (CPU_FAN)
Does the motherboard's Cpu fan connector have the same number of pins needed, as the fan cable connector requires?


B) If this Heatsink/Fan combo, (Sanyo A38001-001) has been installed for quite some time, check to see if the Thermal Paste has dried up, or is drying up.

Since 2004?
Yep, you better pull that Sanyo A38001-001 off, and check the Thermal Paste.
Computer unplugged from power, OBSERVE Anti-Static Precautions.
A Processor is the most susceptible hardware component to Static shock.

Clean the Processor and bottom of the Heatsink as stated above. Properly apply fresh, new Thermal Paste.

Example of Thermal Paste. (Maybe there is a 'Mom and Pop' computer store near you, that you can buy a one Processor application, for around $2)

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=16826&CatId=503


Check for a loose Cpu fan cable connection.

Make sure the Heatsink/Fan combo is seated tightly on the Processor.

MPC 375 cpu fan is running on High. I swapped another fan assembly in and it still is running high speed. I swapped another power supply in because the computer wasn't booting. Now it boots but fan is...


The MPC Clientpro 375?
It has an Intel Pentium 4 model 640 inside.
(3.2GHz, 2MB L2 cache, 800MHz Front Side Bus)

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_2M_.2890.C2.A0nm.29

When operating at maximum, they can draw up to 84 Watts.
These puppies run HOT!

Need to make sure the thermal paste hasn't dried up.
If MPC used a thermal pad, take it off, and use it for a Frisbee. It's junk!

Computer unplugged from power, computer case open, TOUCH the metal frame of the computer case.
(Or wear an ESD wrist s-trap)

Processors are the most susceptible to Static shock, among all of the hardware components inside.

Remove the heatsink, and fan.
Carefully clean the top of the processor case.
I use an old plastic credit card to scrape the thermal paste off. Then I follow up with Q-tips dipped in Isopropyl Alcohol.

(Note - Q-tips. Sometimes it's a gooey mess, and takes Several Q-tips.
Isopropyl Alcohol = Rubbing alcohol.
Try to get the 91 percent alcohol, 9 percent water version, or higher if available.
[91% alcohol]

WARNING!
Isopropyl alcohol is Extremely Flammable.
Burns clean, so it's hard to see when it IS burning.
Keep away from open flames, and sparks.

After I clean the top of the processor case, I sometimes follow up with a hairdryer set to low, and move it back, and forth over the processor about 1 foot away.
[Makes a lot of sense after I just stated the Caution above, huh?] {Sarcasm}

Since the rubbing alcohol does contain a small amount of water, I like to insure it is indeed dry, before I apply thermal paste, and the heatsink/fan combo.

The bottom of the heatsink is cleaned in the same fashion. Apply a small Pea sized drop of thermal paste, to the center of the processor case.
Install the cleaned heatsink/fan.

Try to look across the motherboard at a side view, if possible, to see that the heatsink is seated flat on the processor.

When tightening the screws down for the heatsink, alternate when tightening.
Tighten one turn on a screw, go to the Opposite corner, and do the same.
Keep alternating as you tighten.

Granted there are springs around the screws, so that even pressure will be applied, but you can put too much pressure in the wrong place.

The heatsink will not truly set flat, if the screws are not tightened correctly.
Your processor will run hot, causing fast fan Rpm's.

My system turns on but no video only audio whats going on i even bought new av cables still same


Hi its about to go into RROD quick fix to tell if it is sometimes this works

Turn it around see the fan holes, with it turned off stick two small screwdrivers thru the holes to stop them spinning, turn it on watch the lights on the front, soon it will blink 2 red lights let it go for about 10 minutes then turn it off at the wall,take out screwdrivers, wait for about an hour to cool by itself, dont help it Turn it on at the wall and 90% of the time it will come alive again if not do it a second time If this helps give us a tick so to help others This is temporary untill you get it fixed by a professional to fix them properly and if its under warrantee MS is the best way to go otherwise you have to heat it with infared heat or a rework station clamping is basterdation in my opinion I use the rework station and about 95% are still going Good Luck
