The most likely Culprit is an integrated (Built into the motherboard) or OEM (Original Equipment from Manufacturer) Video card that is "Borrowing" some of the system memory to provide video Memory.

This can happen EVEN if you have a standalone retail card, if the integrated one is still enabled in the BIOS (Basic Input Output System)

To resolve this open the BIOS (Usually pressing <Delete> or <F12> during the boot up process

search through the menus until you come to the settings for your onboard Video card. If you have a standalone card DISABLE the onboard video. If you are using the integrated video then you should be able to adjust the amount of Memory you want to allow the Video card to "BORROW"

If the above situation does not apply to you, please let me know some more information about the problem so that I may assist you further

Thanks
Dave

Dvd writer not recognising any disc.just says insert disc


Make sure it has power (ejects). Check Device Manager in Safe Mode by pressing F8 during boot. Right click My Computer > Manage. Select Device Manager > View > Show Hidden Devices. Now delete all DVD/CD-ROMs and reboot. Windows will say "New Hardware Found" and install. Check BIOS by pressing F key (correct F key is noted during boot) and make sure BIOS see's the Optical Drive.

I'm having a problem with HP DC7900 SFF. The Video Card shared memory is 1GB. according to there technical paper maximum should be 384MB only. I'm using winxp sp3 with 2GB memory. How can i change...


The amount of allocated shared video memory is configured in the BIOS configuration.
Go into the BIOS - video memory to change the amount of video RAM..

If i change the ram stick will my pc reconise it


Yes.

Provided,
1) It is no more than the maximum amount, for that ram memory slot.

2) Adding it, will not go over the Maximum Total Amount for the motherboard.

If this pertains to an Acer Aspire T135 desktop computer,

A) The Maximum Total Amount is 2GB.

B) The Maximum Amount for Each ram memory slot is 1GB.

C) PC3200 is the best you can use.
DDR Sdram at 400MegaHertz. (400MHz)

[It can also use PC2100, and PC2700.

DDR Sdram at 266MHz, and DDR Sdram at 333MHz, respectively ]

Once you install the ram memory, BIOS should automatically find it.

If you are only going to use one ram memory module, be sure to put it in Slot 1.
The Processor reads ram memory in Slot 1 first.

[Slot 1 is closest to the Processor.
It may have DIMM 1 printed on the motherboard, next to Slot 1 ]

How can my computer recognize my new ram i insert?


If it is the correct RAM the System should recognize it automatically. Window on the other hand sometimes get it wrong, To see how much RAM you really have is check as it boots up, that will give you the correct amount. OR again check in BIOS.

Dell vostro 400 2 beeps in bios post test


Hi...

The cause of beeping is the memory problem. maybe the memory stick is not inserted correctly. If your memory stick will not correctly inserted it will damaged the memory slot. Try to use the other slot, if the same thing happen. You memory slot will be damaged you need to bring you motherboard to the computer repair center. Ask first how you will pay, if the labor cost is high. its better to buy a brand new motherboard.

Tried to upgrade ram with 2 new pc133 sticks of 256mb ea. Didn't work. What's wrong? Are there switches on the motherboard I need to change? Or something else?


No there are no DIP switches to change, or jumpers to move on your motherboard, in regards to your BIOS recognizing ram memory installed.
(BIOS. Basic Input/Output System. This tiny program, {64MB in size usually}, that is burned into your BIOS chipset, is what recognizes ram memory on your computer)

Things to know about the older Sdram ram memory.
1.It's really SDR Sdram. Single Data Rate Synchronous Dynamic Random Access Memory.
DDR is Double Data Rate Sdram, DDR2 is Double Data Rate 2 Sdram, and so on.

Point? All ram from SDR to DDR3, IS Sdram.

2.Standards have been set by JEDEC for computer ram memory starting from DDR Sdram on up. This standards were not implemented back in the day of SDR Sdram.

Point? Ram memory manufacturers didn't all follow the same standard, and ram memory made for one computer, would Not work in another computer.
This means you need THE ram memory for YOUR eMachines computer.

Main factors when buying SDR Sdram,
A.Correct type. You know this. SDR Sdram.
168 gold plated contact pins on the bottom of the ram 'stick'. (82 on each side)

B.Correct 'Speed'. ('Speed' is slang for Frequency Rate) You know this. SDR Sdram that operates at a frequency rate of 133MHz. (Or also known as PC133)

C.It must be low density Non-ECC ram memory. It cannot be high density ECC. (Error Control Correcting. Used for Server computers mostly)

D.Correct CAS Latency. Also known as Ram Timings. 3-3-3-3-2 would be normal for SDR Sdram.

E.Correct Chip Configuration. How the DRAM chips are accessed. DRAM chips are the black rectangular chips on each side of your ram memory 'stick'. Also what size the DRAM chips are in MegaBytes. (MB)

F.What the Maximum TOTAL Amount is for the motherboard. Is it 256MB? 512MB? Or more?

G.What the Maximum Amount is for EACH ram 'slot'. (Correct speak for 'Slot' is Bank)

H.Do you have four ram 'slots'? You MUST have a ram stick in Slot 1. This is the slot closest to the processor. It is the first ram slot the processor 'reads'.

The 256MB SDRAM is showing as 128 MB SD RAM


if you have onboard graphics card that shares the ram memory with your graphics card then the configuration in the bios will determine how much memory is shared with your graphics card so you will lose memory there. Also windows xp does not always report the correct amount of memory so check with cpu z or wcpuid or another utility to check.
Also when you restart your computer when it detects the memory how much does it show that is installed there or if you go into the bios does it show the correct amount.
If it does not then it is not compatable and I would suggest going to www.crucial.com and selecting / getting the correct memory by selecting the correct computer / motherboard that you have.

Installing memory upgrade


No.
Once you install the memory into the slot the BIOS will update the memory configuration during the bootup proccess.
You can check to see if your new memory has been fully recognised by double clicking "System" in control panel.
If you check the amount of memory in System before the install and compare it afterwards you will know for sure if the memory has registered correctly.
