There is a step-by-step procedure for solving the problem at this url:
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01912228&tmp_track_link=ot_faqs/top_issues/en_us/c01912228/loc:10&cc=us&dlc=en&lc=en&product=5128908
This solution applies if you are running Windows 7, but may also work with 8 and 8.1 versions. This gives several potential causes for your problem, but the most likely are the first three: the speakers are muted in the audio configuration; the volume for the speakers or the application (more likely since you can hear through headphones) is set too low in the volume mixer configuration; or your speakers are not set as the default playback device (sometimes SPDIF is set as default instead). The others are pretty uncommon, but can happen, so don't give up if none of the first three corrects the problem.
For an Asus P4S800D-X desktop computer motherboard?No problem, Luz.The cables you have indicated are Power Supply cables.Let me show where they go;First I would like you to download the Motherboard Manual.It will also come in handy later,http://www.asus.com/Motherboards/Intel_Socket_478/P4S800DX/#downloadClick on the Download tab.(Overview,Specifications,Download,Memory/Device Support,etc)Scroll down, click on the + sign next to - Manual (6)Scroll the page down to the bottom file, then click on the blue - Global (DLM), underneath -Version E1753 / P4S800D-X User Manual English Version E1753{ Note* To the right side there is a blue scroll bar. You have to scroll it down to see the blue Global (DLM) ]}[ Ignore if you are aware. This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.After you click on Global (DLM), it may take up to 30 seconds, before the first page comes up.Took 10 seconds just now using a medium speed DSL connection.At the top of the PDF file is the page number box, to the right of the Down Arrow. When I refer to a page it is this box I refer to.At the top header of the PDF file also, is the Zoom In icon ( + ), and the Zoom Out icon ( - )Zoom In increases the view size.Zoom Out decreases the view size ]Do not know exactly, what the P numbers on the power supply cable connectors are, that you have. Do know the normal markings, but it may vary.It DOES NOT matter however. I will show you photos of the power cables, and will guide you where they go.Go to Page 13.Look at the top right corner. ATXPWR1. (Can't see it clearly? Use the Zoom In icon)1) This is for the 20-pin ATX main power cable, coming from the Power Supply. This is an example of a 20-pin ATX main power cable, and it's respective connector on the motherboard,(Note* Color DOES NOT matter. Color of the connectors can be ANY color ),http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20Probably marked as P1.Now look at all three photos. In the middle photo you will see a Lock, on the side of the power cable connector.It acts like a see-saw on a playground. You squeeze the top in, and the hooked end of it comes away from the connector.Now look at the photo to the left.The motherboard connector has a matching Tab, for the hooked end of the Lock, to go over. When the power cable is correctly plugged in, and tightly, the hooked end will go over that tab.2) 4-pin ATX +12 Volt power cable:Look at page 13 again. Note where the Processor sits.(Has a Fan on top of a finned Heatsink, which sits on top of the Processor )Come down below the Processor, towards the Northbridge chip. It has a Heatsink sitting on it. It is placed as a diamond shape.Look to the left of that diamond shape. You will see a small square socket, with 4 socket holes. (Probably white in color)This is where the 4-pin ATX +12 Volt power cable plugs in. It also has a Lock on the power cable connector, and a matching Tab on the motherboard connector. Can ONLY be installed in one direction, because of the Lock, and Tab, just like the 20-pin ATX main power cable.This is an example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4Probably marked as P4.THAT, is it, for power cables that plug into the motherboard.Do NOT know if you are using an IDE, or a SATA harddrive.Will post for both.A) IDE harddrive:An IDE harddrive uses a 4-pin Peripheral power cable.(Standard 4-pin Peripheral power cable, really. Explanation later)Looks like this,http://www.playtool.com/pages/psuconnectors/connectors.html#peripheralNote that the 4-pin Peripheral power cable example, is also shown plugged into an IDE harddrive. (EIDE)May be marked as P2, P3, P5, P6, etc. DOES NOT matter what P number it has, Luz.As long as it looks like this, it will be FINE. Use any P number you want.{ Note shape of connector. Has rounded corners on one side. ONLY plugs in one way.Note also that it has;1 Red (5 Volts) wire, 1 Yellow (12 Volts) wire, and 2 Black wires. (Ground wires. ALL Black wires are Ground wires}B) SATA harddrive:Uses a SATA power cable. Note that a SATA power cable has 15 contact pins. It is LONGER than the 7 pin SATA data cable.Note that the inside shape is an L shape. ONLY lines up one way,http://www.playtool.com/pages/psuconnectors/connectors.html#sataNOTE*IF, you have a SATA harddrive, that has a provision for a 4-pin Peripheral power cable, AND a SATA power cable; ONLY use the SATA power cable! DO NOT use both.You will burn up the SATA harddrive. May not happen right away, but I assure you it will happen down the road.This is what a SATA data cable's connector looks like,http://en.wikipedia.org/wiki/File:SATA_ports.jpgTop photo. Again, color DOES NOT matter. Also note the L shape in the center of the connector. Both the power cable's connector, and the data cable's connector, have this L shape in the middle.Goes over the L shape of the Harddrive's connectors.[ SATA optical drive, (CD/DVD drive), also has an L shape for it's connector ]IF you have a card reader it uses a Small 4-pin Peripheral power cable. Now you will see the difference, and why the other 4-pin Peripheral power cable is designated Standard,http://www.playtool.com/pages/psuconnectors/connectors.html#floppyUsed to be used for a Floppy drive. Note the colors of the 4 wires.Red, Yellow, and 2 Black wires.Have more than one, and have a card reader? DOES NOT matter what the P number is. As long as it looks like this, you can use ANY of them.For additional questions please post in a Comment.{ Also, the first 4-pin Peripheral power cable connector, was made by Molex.The name stuck. Molex power cable.Ummmm, NO.Kind of like the adjustable open-end wrench, being called a Crescent wrench }Regards,joecoolvette
no place them this way if one kind is kingston or whatever a1 b1 and the other kind makes no difference as long as their in the right sockets/ a2 b2 these should be colored so if you have 2 of one kind and 2 of another you would keep them in the perspective colors ?dual ram is usually done this way you would have 1 gb in a1 and the other in b1
It can. Just depends on what is wrong with the motherboard.
If the damage is too extensive, then it becomes expensive, and it's cheaper to just replace the motherboard.
General repair is usually the Electrolytic Capacitors on the motherboard. The entire correct name for the capacitors used, is Radial Aluminum Electrolytic Capacitor. (Regarding the Asus P4S800D-X motherboard)
{With an Axial capacitor design, the leads come out of the ends. One lead out of one end, and the other lead out of the opposite end. (Lead. Think stiff wire) With a Radial capacitor design both leads come out of one end.
On the above page go to the Second photo down on the right. Shows a side view of two Electrolytic Capacitors. The Black one with white letter/numbering, and arrows, is an Axial design. The blue one below it that has the leads coming out of one end, is a Radial design }
Looking at the motherboard photo shown at the top of FixYa's page, you are looking at a TOP view of the Electrolytic Capacitors. Better view,
The Processor socket is to the middle/right. Black plastic rectangle around a rectangular white socket. The black plastic rectangle is a Heatsink mount. Above it you see 7 silvery dots circled in black.
These are Electrolytic Capacitors. (Radial Aluminum Electrolytic Capacitors) The silvery dot is a Vent Cover. The black ring is part of a black plastic sleeve, that goes around the capacitor.
These capacitors are Voltage Regulators. They are part of the motherboard voltage regulator circuit. These capacitors, and others not in the general vicinity, regulate voltage for the Processor. A Processor MUST have a steady, 'clean' supply of voltage. A Processor has a VERY tight tolerance range. Can't be too much, or too little.
If just ONE of these babies are bad, the Processor will not turn on, or stay on. (They are in a Series circuit)
The ones you see to the far left that are in-between the long white PCI slots, and the brown AGP 8x graphics slot, are used as Filters. It takes more than one being bad to bring the motherboard to it's knees.
First thing to check. Electrolytic Capacitors. Visual guide to bad capacitors,
Capacitors are rated in Voltage, and Microfarads. This info is Usually on the side of the capacitor. But not always. Capacitor manufacturers also use a manufacturers code. More info on this,
Electrolytic Capacitors are the weakest link. The computer design engineers know this. They know that after time an Electrolytic Capacitor will weaken. This is why they use capacitors that are 50 percent better than needed. After the capacitor weakens to the 50 percent good stage, it is still at 100 percent for the task that is needed.
Also; There was a small period of espionage back in the 70's, regarding an Electrolytic Capacitor paste formula. The Electrolytic Paste used in an Electrolytic Capacitor, is a closely guarded secret.
Someone decided to steal a particular Electrolytic Capacitor manufacturer's paste formula. The manufacturer found out beforehand, and slipped the thief a bogus formula. The formula was for a paste that goes bad after time. Develops a gas.
1000's upon 1000's of these capacitors were made, and sold. They are still plaguing us today. The capacitor may operate okay for a few days, weeks, months, or years. There is just no way to tell. (In all kinds of electronic components. Not just computers)
Past Electrolytic Capacitor failure, the motherboard chipset is usually next. However motherboard chipset failure is usually rare.
The motherboard chipset technology used for the Asus P4S800D-X motherboard, consists of a Northbridge chip, and a Southbridge chip.
(Chip and Chipset are slang terms for I.C. Integrated Circuit)
Looking at the Asus P4S800D-X motherboard in the Asus Support link, look to the left of the Processor socket.
The square silvery heatsink that looks like a meat tenderizer, and in this position looks like a diamond shape, covers the Northbridge chip. If the Heatsink were removed, you would see SiS 655X on top.
To the left of the blue Slot 1 (DIMM 1) ram memory slot, and the black Slot 2 (DIMM 2) ram memory slot, is the Southbridge chip. No heatsink on top. It is a SiS 964
These chips are mounted to the motherboard with a BGA surface mount. Ball Grid Array. To explain the BGA surface mount, let's compare to your Processor, and it's processor socket. (Socket 478 processor socket)
On the bottom of the Processor are contact pins. 478 of 'em. The contact pins line up with the socket holes in the processor socket. (478 socket holes)
With a BGA surface mount there are no contact pins, nor socket holes. The bottom of the chip has Solder Balls. The mounting surface of the motherboard has Copper Pads.
The chip is set down on the motherboard, with the Solder Balls matching the Copper Pads. Heat is then applied at a specific temperature, and length of time. The Solder Balls melt, which solders the chip to the motherboard. (Solders the chip to the Copper Pads on the motherboard)
It takes a BGA Rework Machine to effectively remove, and replace a chip mounted with a BGA surface mount. Not something you'll find in an average computer repair shop. Therefore C-O-S-T-L-Y to have done. Also access to the correct chips isn't that easy.
Next would be replacing one of the expansion slots. Or the BIOS chipset. Except for capacitor replacement, the other replacement parts, and procedures, are more costly than just procuring another motherboard.
Sorry to be so lengthy with my 'solution'. Just thought I would pass this information on, and also wanted to give you insight.
For additional questions please post in a Comment.
Hello,It sounds like either your motherboard of video card (if applicable) is defective. You should take your computer to a repair shop and have them run a diagnostic to determine which one it is.
Visit the Asus website and find your motherboard and from the support and downloads menus you can get the driver you need. Be sure to state that it's a Win7 driver you need
