I have to say i strongly reccommend u take it to an expert.. it could be so dangerous for u to take on this job.. even i wldnt try it and i no wot im doing lol. A capacitor a passive electrical component that can store energy in the electric field between a pair of conductors (called plates). ur pc cud b turned off for a year but these conductors store th energy indefinately..so even after being off for a year if u were to place ur finger btween these conductors u wud get such a boot off it ud wonder whr all ur extremities went to and ud have a diff hairdo lol.. unless ur confident (and preferably qualified lol) i wld strongly urge u not to.. sooo not worth it..and unless qualified any do-it-yourself u take on is ur own responsibility. and unless u understand th next line..jus dont bother lol

What motherboard should i put in my HP - Compaq Pavilion p2-1013w


Dismantle the computer so the motherboard and mounting plate is free. Remove the motherboard off the mounting plate.
Most mounting plates have several standard mounting stand off positions so it can fit various motherboard from different manufacturers. Go to a computer parts shop with the mounting plate and select the motherboard of your choice then position the motherboard over the mounting plate to see if the motherboard mountings line up with the mounting plate holes.
You may also need to install a switch mode power supply with a higher wattage rating.

David,

FOLLOWING Anti-Static Precautions?

OK.
Using a decent light, what shape are the Electrolytic Capacitors on?

There are Solid Polymer Capacitors. One on one side of the Processor, and 3 on the other side,

http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01324212#N155

Those little 'cans' have a Red mark on one side, on the top.
Others used have a Blue mark.

Not talking about those. If they were bad you'd know it. They explode like miniature grenades, and throw shrapnel all over inside the computer case.

Referring to the Radial Aluminum Electrolytic Capacitors,

A) http://capacitorlab.com/visible-failures/index.htm

B) http://www.youtube.com/watch?v=Lut7MX5Dd_A

Did you install the 2 -2GB 'stick's in the Blue Ram Memory slots?
Reasoning?

Slot 1, or also known as DIMM 1; is the first blue Ram Memory slot that is closest to the Processor.
The Processor reads what is in Slot 1 first. MUST be a Ram Memory module ('Stick') in Slot 1.

Most prefer to run Ram Memory in a Dual Channel configuration; so the other Ram Memory module should be in Slot 3.

Do you have the old Ram Memory?

Cleaned under Mobo;

The motherboard is mounted to a Support Plate.
The Support Plate can be a separate metal plate, or is an integral part of the computer case.

Mounting of motherboard TO Support Plate is accomplished by plastic Spacers, or metal Standoff/s.

If metal Standoff's are used, and ARE able to be moved, is there one that is in the wrong place? Not matched up to a motherboard mounting hole?
If one is (Or more) it can touch the exposed solder joints, on the bottom of the motherboard, and cause a Short Circuit.

Most of the time removal, or placing to a motherboard mounting hole, will allow the motherboard to work again.

Post back in a Comment.

(If yourself, or someone did Not follow Anti-Static Precautions; when handling the motherboard/working on computer, you may be looking at a pile of junk, now )

Dell Optiplex 745 having all kinds of problems getting blue screens, but I can reboot and it works fine. I installed a new hard drive on this computer. I am not able to install the update for windows xp...


Hello,

The main failure on the Optiplex 745 units are capacitors on the motherboard. When they fail you can get all sorts of strange problems - no boot, blue screen issues, no video or distorted video. Open your machine up and look for bulging capacitors on the board. Here is a link to a guide showing what to look for on the motherboard to determine if your problem is capacitor related or not.

http://www.ccl-la.com/blog/index.php/dell-optiplex-745-repair/

If you do find bulging capacitors on the motherboard then more than likely that will be your problem. You can replace the capacitors and your board will be as good as new.

I hope this helps, if so please rate my solution.

Hi i m pravin from INDIA . i m newly assemble mother bord but p.c. start only 30 sec. then off so what can i do


1) The metal plate that the motherboard mounts to is a Support Plate.
It can be a separate metal plate from the computer case, or part of the computer case itself.

Some Support Plates that are part of the computer case have protrusions, or 'Bumps' formed, that hold the motherboard up off of the Support Plate.

Other designs of Support Plates use metal or plastic supports that space the motherboard away from the Support Plate.

These supports are Spacers, or Standoff's.
A Spacer is made of plastic.
A Standoff is made of metal.

The metal standoff's have a hex shape around the middle, a threaded end on one end, and a threaded hole on the other end.

The Standoff's MUST match the motherboard mounting holes.
There Cannot be a Standoff sitting out on the Support Plate, that does not line up with a motherboard mounting hole.

If there is it can short the solder joints on the bottom of the motherboard, and cause the motherboard to short out.

Sometimes removing the motherboard, and making sure that all metal Standoff's line up with the motherboard mounting holes, will fix the problem.

Other times it is too late, and the motherboard is damaged.


2) Make sure ALL power cables from the Power Supply are attached, and securely attached.

If the motherboard requires a 4-pin ATX +12 Volt power cable, make sure it is plugged into the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

If the motherboard requires an 8-pin EPS +12 Volt power cable, make sure you are not using just one 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#eps8


3) Be sure you have a KNOWN to be good Power Supply, and it has at least the minimum Wattage needed for your computer build.

4) Make sure the top of the Processor's case is clean, and the bottom of the Heatsink, and that Thermal Paste is applied, and applied properly.

5) Make sure you observed Anti-Static Precautions when you were building, and are building your computer.

Static shock will ruin a computer.

May be a cpu problem. Make sure the fan is on the cpu and that it is running. If the fan is running you may need to change the thermal compound that is between the cpu and heat sink. If that doesn't work , the next step would be to try to use another cpu that you know is good and see if it fixes your problem.

Pls why sametime mortherboard whet off how will i solve the problem


Those computers have a problem with bulging capacitors on the motherboards. Look at the little cylindrical things on the motherboard. If the tops on any of them have bulged, you need a new motherboard.

Video went out-mb looked like 5 or 6 bulging capacitors. replaced with used same mb, used processor. did not start up with 500watt power supply. do i need to replace with emach power supply? emachC6423


Hi,
Probably not providing the block connectors are the same.

Make sure you have your memory seated properly and also clear the CMOS if you have the option. If you don't remove the power supply to the motherboard and take out the CMOS battery for an hour.

While you are waiting take a close look at the caps that you replaced to make sure the are the right way round, use the other motherboard as a guide.


Good luck.

Gateway lp2207 appears power supply has burn out...is worth repair any suggestion on repair


Actually the problem is one of the capacitors on the power supply.
 
I have the same monitor Gateway LP2207 and just replaced the capacitor.
 
Here is a step by step guide (I could not find anything on this monitor except what is on this site which is not much)
 
1. Remove the stand by taking out the 2 screws
2. Remove the 4 Wall mount screws
3. Remove the 3 screws at the bottom back of monitor
4. Pry the rear case off by starting in either the left or right corner at the bottom and work your way
to the center. (Note you WILL break off a little piece of the retainer clip on the inside but its not a major concern as you will not see it when you put it back together) Once you get it split a bit you need to work your way around the sides very carefully.
5. Once you get it split do not pull off the front bezel too fast as the tape wire for the front controls will be attached, all you need to do is pull up in the direction the cable is running and it will pull out very easy, be careful not to damage this tape wire.
6. Once you get the front bezel off there are 4 screws retaining the LCD cage to the rear case, remove these 4 screws.
7.Set the front and rear case cover aside and lay a soft towel down and flip the LCD on its face, next there are 4 screws securing the LCD into the LCD cage (Please note I’m not a professional and don't know the exact names for all the parts but I think once you get the case open you will understand what I'm calling what)
8. Remove the 4 wires on the left of the unit and the cable grouping on the right. you will also need to remove all the taped wires that are secured to the LCD cage.
9. There are 2 parts to the cage, you will need to only remove the top 4 screws and the 2 screws where the monitor speaker is. This is needed only because in order to get the power supply out you need a little space to remove it.
10. Remove the 2 screws where the power cord plugs into
11. Flip the unit over so that you can see the power supply and the video board and remove the * screws holding the power supply into the cage.
12. Remove the wires from the Video board going to the power supply board, you will also need to remove the wire going to the USB hub, this can be done by removing the 2 screws holing the metal protection plate and then pull the wires from the hub.
13. Now remove the power supply and look at the capacitors on the board, you will see the top of the capacitor has a bulge on the top, that is the one that needs to be replaced.
 
Now here is the good part! if you know how to solder Go down to your local Radio Shack and get a new capacitor for 2.00, replace the capacitor, if not then take the board to your local TV repair shop and tell them to replace the capacitor, it should only cost you about 25 -35 bucks since you did all the work pulling the monitor apart and it only takes them 10 min to remove and replace the capacitor.
 
Now once you have it repaired put it all back together in the reverse order and you will have yourself a repaired monitor for 35.00 and an hour worth of your time.
 
I hope this has helped anyone with this monitor and has saved you the time that it took me to search the net (I looked for 2 days and found nothing)

N15235 win fast motherboard


The main cause behind this problem is :-
1) RAM JAM
2) HDD is taking extra power from SMPS
3) Motherboard faulty Capacitors / ICs
Try following :0-
step 1) Remove CMOS Battery (3V battery) + RAM
and now try to check whether Fan shows same symptoms or not

Step 2) if results of above step is fail then try to remove HDD powersuppy + CD/DVD power supply + Floppy Power supply (in short provide power to only motherboard) and now start the system.

If the result are same
3) then look for any swollen capacitors on motherboard, if they are then you need to replace them.

4) If no capacitor is swollen then check for every bigger IC on motherboard for whether it got excessive heated or not. If yes then you need to do serious operations on your motherboard .
Please not here i have used the word EXCESSIVE HEATED. and noth the normal heated

Dell OptiPlex GX270 PC Desktop Problem


Dell did confess that it had some problems with the products it rolled out. http://www.news.com/Bulging-capacitors-haunt-Dell/2100-1003_3-5924742.html If you think your motherboard has the same problem as bulging capacitors. then you can call them and get it replaced. you are eligible for that.
