Assuming you are running Vista; you can find out what the problem may be by going to control panel> system & maintanence> administrative tools> event viewer>windows logs. look in all the catagories to see if there are any clues as to your problem, but normally i would say it's a graphics driver error or processor overheating, especially if you have onboard graphics and not a seperate dedicated graphics card.

Need motherboard specs website


There are two views of the motherboard. By default when the link is clicked on, the Bottom view is the large main view.
(In the two views shown, it is the view on the Left )

Looking at the Bottom View;

1) The Pink(?) square socket you see at the top is the Processor socket.
(CPU - Central Processing Unit. Another term used is Microprocessor, or simply Processor)

It is a Socket P mobile processor socket,

2) Processor?
Dell gives you options, so it's hard to say what Intel processor is on your motherboard.

The Intel GM45 mobile chipset, supports mobile processors that are Intel Core2 Duo, Intel Core2 Extreme, and Intel Celeron M.
A 667MHz, or 800MHz, or 1066MHz FSB is supported.

I have seen an Intel Core2 Duo, model T6400 offered, so I know it supports using a Socket P processor socket, uses a 1.00 to 1.250 voltage range (DC), and the Penyrn-M Core, and 45nm technology,

Laptop disassembled the easiest way to find out, is to put an ESD wrist ********, connect it's alligator clip to a good ground source, and look at the Processor.
GENTLY use an old credit card, to scrape off as much if the thermal paste as you can, then use Q-tips dipped in Isopropyl Alcohol.

(Takes a bunch of alcohol soaked Q-tips)
Look for the sSpec Number, and the Part Number. Then 'google' it.

Isopropyl Alcohol is EXTREMELY FLAMMABLE!
Use in a WELL ventilated area with NO sparks, or flames present!]

Laptop together, functional, and internet ready, use CPU-Z from to find out.

3) Below the pink Socket P processor socket is part of the motherboard chipset.

The Northbridge chip.

It is an Intel GM45 chipset, it is an SMD (Surface Mount Device), and uses a BGA surface mount,

BGA surface mount.
Ball Grid Array surface mount.
View a BGA Rework Station in use, and learn in detail what a BGA surface mount is,

Scroll down, click on the red - Take a few minutes to view the IR 650 video demo

The Southbridge chip is an Intel 82801IMB, (ICH9-M)
It's on the Top of the motherboard.

[Chip and Chipset are slang terms for I.C.
Integrated Circuit,

(A Processor is an I.C.) ]

The motherboard chipset is the Northbridge chip, and the Southbridge chip.
(Does Not apply to motherboards that support the Intel Core i3, Core i5, Core i7, and Core i9 processors)

The Northbridge chip handles the Faster capabilities of a computer.
The Processor, Ram Memory, and HIGH-speed graphics.

AGP (Accelerated Graphics Port), and PCI-Express, are High-speed graphics.
A graphics card using a PCI expansion slot, and Integrated graphics, is Not high-speed graphics.

[Integrated Graphics used to be referred to as OnBoard Graphics.
ON the motherBOARD. Easier to understand ]

The Southbridge chip handles the Slower capabilities of a computer.

1) Anything connected to the PCI bus.
PCI expansion slots, or OnBoard Graphics.

2) Anything connected to the IDE bus
3) SATA bus
4) USB bus
5) Ethernet bus
6) Audio (Sound)

[CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor, for short ]

As you can see Serial Ports, Parallel Ports, Floppy Disk drive, the Keyboard, and Mouse, are connected to the Super I/O chipset.
[I/O = Input/Output. Input and Output devices ]

I do not know what Super I/O chipset is used.
You may want to look through this chart, and see yours matches up with one of them, (They are probably too old, but gives you an idea of what to look for),

There are Two Ram Memory slots. (Seen on bottom of motherboard)
Maximum Amount for each Ram Memory slot is 4GigaByte.
Maximum TOTAL Amount is 8GB.

Uses DDR2 Sdram that is SO-DIMM.
(Small Outline Dual Inline Memory Module)
Smaller in size than desktop computer DIMM.

Can use either DDR2 Sdram at 667MegaHertz, or 800MHz.
(PC2-5300 and PC2-6400, respectively)

Uses a 2.5 SATA harddrive.

Continued in an added Comment.


Maximum graphic card memory

You could increase to a 1000Gig's if they made one.

A graphics card has it's own graphics processor, and graphics ram memory. It runs independent of the System Resources.
The Processor and Ram Memory.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

The graphics I.C., or graphics chipset, is a GPU,

A GPU can be mounted directly to the motherboard, and use some of the system resources. Integrated graphics.
Or it can be mounted to a removable graphics adapter card.

IF there IS a 'bottleneck', it will be your Processor, and amount of Ram Memory.
Should have at least 2GB of ram memory
It will take up to 4GB. can also support DDR2 Sdram at 667MegaHertz. (PC2-5300)

Intel 945G motherboard chipset.
Intel 82945G Northbridge chip,
Intel 82801GR Southbridge chip. (ICH7R)

Supports Intel Core2 Duo processors, with a Front Side Bus of
UP TO 1066MegaHertz. (FSB up to 1066MHz)

Intel 945G chipset was brought out in 2005. This means to me, the PCI Express technology used on your motherboard, is
PCI Express 1.1

I would stick with the graphics cards using PCI Express 2.0 technology.
I've read reports where the PCI Express 2.1 cards, weren't 'playing nice' with motherboards using the PCI Express 1.1 technology.

Unless you just wanta' experiment? Who knows?

How many maximum Watts is the Power Supply, capable of delivering at 80 percent, and how many Amp's does the 12 Volt power rail have?
(If there is more than one 12 Volt power rail, you can add together for the total 12 volt Amp's )

See what the minimum requirement is for the Power Supply. make sure you have MORE than enough.
Also if the graphics card requires an additional power cable; make sure your Power Supply has it.

But the minimum wattage for the Power Supply is 450 watt.

Power Supply? 500 Watt.

    1 out 50 times I turn on my Dell Dimension E520 there is no signal to the monitor. I have tried to install a new PCI express card instead of using the integrated graphics but the result was the same e.i no...

    The problem is the Power Supply. Weak voltage power rail.

    You've taken the right steps with your diagnosis.

    1) Start with the monitor cable. If removable use a known to be good monitor cable.
    Checks okay, go onto the graphics 'engine' of the computer.

    If the monitor cable is not removable, use another monitor, and cable for a test.

    2) If you are presently using Integrated Graphics the next step in diagnosing is to install a graphics card.
    See if the problem is the Integrated Graphics 'engine'.

    [ Just to add:
    Intel GM X3100 is the graphics 'engine'. It is integrated into the Northbridge chip of the motherboard chipset.

    Intel G965 chipset is the motherboard chipset. The Intel ID number on the Northbridge chip is 82G965.
    The Southbridge chip is an Intel ICH8, or ICH8R, or ICH8-DH,

    {Chip and Chipset are slang terms for I.C.
    Integrated Circuit, }

    The Northbridge chip handles the Processor, Ram Memory, and HIGH-speed graphics.
    AGP and PCI Express are High-speed graphics.

    A graphics card in a PCI slot is not High-speed graphics.

    The Southbridge chip handles the slower capabilities of a computer.
    PCI and Integrated Graphics being two of the slower capabilities.
    SATA, IDE, USB, and Ethernet, are also some of the slower capabilities of a computer,

    CPU = Central Processing Unit. Another name used is Microprocessor, or Processor for short ]

    3) Power Supply.
    Weak voltage power rail.

    The Power Supply has enough power to light LED lights, and maybe spin fans, but Not enough power to turn the Processor on.

    A) ALL the LED lights on at once will consume less than 1 Watt of power.

    B) EACH fan consumes 2 to 3 Watts of power.

    C) A typical Processor can consume (Maximum) 51 to 125 Watts of power.
    Depends on what Processor it is.

    The Dell Dimension E521 desktop computer's motherboard, has an LGA 775 processor socket.
    (Processor has the socket holes, processor socket has the pins)

    The Intel processors that can be used in this processor socket, can be an Intel Pentium 4, (Version that uses an LGA 775 processor socket), Intel Pentium D, or Intel Core2 Duo, AND Intel Core 2 Quad, with a maximum FSB of 1066MHz. (If the BIOS version will support Intel Core2 Quad processors)
    {Front Side Bus of 1066Megahertz}

    Wattage consumption can be as much as 105 Watts.

    Do you have a KNOWN to be good, compatible Power Supply available, to use as a test unit?

    {Compatible being that the Power Supply case fits, (ATX), has the right amount of power cables, and the correct power cables. (Needs to have a 24-pin ATX main power cable, and a 4-pin ATX +12 Volt power cable, for one)

    Perhaps there is an unused computer that has a Power Supply you can borrow.
    Maybe someone has upgraded to a better computer, and has an unused one with a compatible power supply for a test unit.

    My cpu fan is not working,is my prossesor working

    Don't know! If you posted this message with that machine, I would have to say yes it is. However, I would definately not run this system for more than a minute or two unless you have the fan replaced. If the processor overheats, it will destroy the processor and possibly the mainboard. If it's critical thaqt you use the machine, you can open the case and get a small fan that is directed right into the case. That should be a temporary only fix.


    Mother board problem

    sounds like video card driver issue...ensure driver is correct by looking at video card in device manager. Also ensure that system interrupts are being allocated properly.
