I can not open my bios

My power supply, RAM (physical memory), VGA card, Hard Disk everything is ok. But when I start my computer I can not open my bios. I have talked to some hardare exparts. They told me that my motherboard is out of order. I have faced a servicing centre in my country Bangladesh. They told me that they dont have equipment to check such a backdated motherboard like this (mainly RD RAM supported). Now what can I do?

Re: I can not open my bios

Dom you see anything when you turn on the computer? Like the Whattype of board and as soon as you turn on nthe computer you should be rapidly pressing the f1, f2, or the delete button over and over, depending on what the bios key is? It should tell you this too at start up.. If you dont see anything replace the board, as it maybe a fault of the componets on the board and not the bios. Oh and make sure the Microprocessor is plugged in correctly too i seen that problem once before. good luck

Re: I can not open my bios

If you have tried the solution below, you should also put your bios in "configuration mode" Near the cmos battery (looks like a round watch battery), you will see 3 pins with a jumper (small plastic connector) on the first two pins. With your computer off, place the jumper on the 2nd and 3rd pin, restart your computer. This should force it to go into your bios settings. Don't forget to save your configuration, and then replace the jumper back to the 1st and 2nd pins. Let us know if this helps, Best regards, nightdiver

Re: I can not open my bios

If windows is starting then download new bios update from Intel website (make sure to download windows setup exe) and install it from within windows. Setup Key = F2 Also you can try: 1. unplug every IDEs , floppys, PCI cards. Only connect keyboard, ram, processor with heat sink and agp if external, powersupply and On/Off switch. Switch it on and see what happens, after switch On keep pressing F2. 2. Also if no display then change you AGP, it might dead also. Hope help

Ihow to boot up and get display and set bios on msi motherboard g41m-e43

Add one item at a time.
First memory, then graphics card.

Plus you cleared CMOS Error Codes, and set the BIOS Setup parameters back to the factory default settings.

Guess what the default graphics setting is for an MSI G41ME43 motherboard?

Yep, AGP.

[Wow, I like MFlash, and the solid Polymer capacitors.
Live BIOS Update 5, and Easy OC Switch.

However if the motherboard fails, I'll bet the Integrated Circuit, (I.C., or 'chipset'), that controls APS, is the first electronic component to go.

I would also watch OC'ing. Has to be done in incremental steps. Automatic feature or not. A 20 percent boost is A LOT.
Hardware components have as tendency to heat up.
Watch it as this lowers the 'life expectancy' of the chips.
Heat - 'Kills' ]

Motherboard chipset:
Northbridge is an Intel 82G43. Southbridge chip is an Intel 82801GB part number. (ICH7) You can't see them as they are under Heatsinks.

Scroll down.

Ram Memory:
Two ram memory slots for Dual Inline Memory Modules on the motherboard. (DIMM)

B) 1.5 Volt (DC)
C) DDR3 Sdram at either 800MegaHertz, or 1066MHz.

[ This puzzled me. DDR3 Sdram at 800MegaHertz?
Why would anyone want to use DDR3 Sdram at 800MegaHertz?
Seems to me going backwards.

Faster frequency rates.
Low end for DDR3? 1066MHz.
High end for DDR2? 800MHz.

DDR3 is faster in comparison to DDR2 per se, because of the prefetch buffer. 8 burst deep compared to DDR2's 4 burst deep.
(Or DDR's 2 burst deep)

Not because of the CAS Latency, though.
DDR3 has a much higher CL, than compared to DDR2.

(Average CL for DDR3 at 1066MHz = 7-7-7-20
DDR2 = 5-5-5-15. Note* -> A-V-E-R-A-G-E. )

When using DDR3 Sdram at least use 1066MHz, IMHO
The maximum ram memory frequency rate, that your motherboard will support ]

So what manufacturer of ram memory is it, and what is the manufacturer code of the ram memory module/s? ('Stick')

JEDEC sets the standards for Ram Memory.
Voltage standard for DDR3 Sdram ram memory is 1.5 Volts (DC)
So the factory default setting is 1.5 Volts, for the motherboard.

However your motherboard supports SPD.
(Serial Presence Detect, )

Point of the above?
If you are trying to use high-performance ram memory; say one needing a slightly higher voltage, and/or has lower CL ratings; then the SPD on the motherboard may make automatic adjustments.
(Adjustments to the parameters in your BIOS Setup)

May take 2 to 3 'Cold Boots', though.
(Turn the computer all the way off. Wait 1 minute. Turn the computer back on = Cold Boot)

I order for SPD to work, BOTH the motherboard, AND the ram memory, have to have SPD feature.
If the ram memory is too low in quality, (Read cheap), it may not have SPD.

Means you have to go into BIOS Setup, and set the ram memory parameters, manually.

[ Delete key to enter BIOS Setup.
Main BIOS Setup menu > Cell Menu > Memory Z > Advance DRAM configuration >
1) DRAM Timing Mode
2) CAS Latency
3) tRCD
4) tRP
5) tRAS
6) tRTP

Don't forget you have to SAVE changes, or it will be as if you have done nothing at all.

If a mistake is made;
Go back to BIOS Setup, and in the Main menu, use the Down Arrow key to arrive at Load Fail-Safe Defaults. IF -> OK is 'highlighted' (Black surround) press the Enter key. If not, use the Right Arrow key, or Left Arrow key, and highlight OK ]

The ram memory also has to be UNBUFFERED.

Unbuffered ram memory is the opposite of Registered ram memory.
Registered ram memory is more stable, usually one clock slower, and more expensive, than compared to unbuffered ram memory.

Registered ram memory is usually used in SERVER computers.

(A Server computer may look at information 2 or 3 times, before it acts on it. It needs to be C-O-R-R-E-C-T for a server computer )

"Cleared the board i believe"

Turned the computer off? Unplugged from power? Pressed the Power ON button in, and held it in for a count of 10 seconds? Then let go of the Power On button, then performed the entire procedure again, 2 more times?

{Clears CMOS Error Codes, and resets BIOS Setup back to the factory default settings}

You MAY have cleared the motherboard. It's what I use, and have recommended for years on the 'net. Doesn't mean it always works, though. Sometimes you just have to go into BIOS Setup, and set the parameters back to the factory default settings.

(For you? Load Fail-Safe Defaults )

A) Won't boot:
Because the ram memory is the wrong one, (Or ones); OR, the ram memory is high performance, and BIOS and SPD hasn't recognized it yet.

Remove the graphics card.(Computer unplugged from power. Anti-Static Precautions FOLLOWED!)
Remove the ram memory.

Reinstall the old ram memory, and plug the monitor into the VGA port, in the I/O area on the back of the computer tower.

Just get the computer working again. After about 10 minutes of fooling around on the computer, ('net?), turn the computer off.
Install the new 2GB.

(IF, just one ram memory module, be SURE to put it in Slot 1.
{DIMM 1} The ram memory slot closest to the Processor )

Leave the computer case open. You may be going back in pretty soon. (Graphics card)
WAIT 1 minute, then turn the computer on.

If no joy shut the computer down. (Press the Power On button in, and hold it in for a count of 10 seconds)

WAIT 1 minute, turn the computer on.
If it doesn't work this time, you may wish to try it again.
Sometimes takes 2 to 3 times, before the high-performance ram memory is recognized.

You can also go into BIOS Setup, as mentioned, and physically set the ram parameters.
After 3 times I would give up however, and send the ram memory back. Wrong one/s.

If you get the new Ram Memory working, Cool!
If not remove it, and use the old ram memory.
Might as well get the computer going with the new graphics card, while you wait on the proper ram memory to arrive.

Did you plug the monitor into the graphics card?
Sometimes we computer geeks get in a wee bit of a hurry, when we get shiny new parts. Make sure the monitor cable is plugged into the graphics card.

There is another tiny thing; DRIVERS
If you did not use the Installation Disk (CD) first, THEN physically installed the graphics card, you are Wrong.

OR downloaded the drivers from EVGA.

What happens if you physically install a graphics card, THEN come back and install the drivers?
Most of the time a Driver Conflict.

Windows: "Which drivers do I use? These or THESE?"

Also sets BIOS Setup to the correct graphics aperture.

With the computer set back to the factory default settings, and the monitor plugged into the VGA port on the motherboard, you can get Windows running, and install, or download AND install, the Drivers.

ONCE the drivers, (And user interface -> Nvidia Control Panel), have been installed, you can then physically install the graphics card.

[Again; If you download the drivers, do NOT forget you have to go to where they are downloaded, and DOUBLE-click on the file, then use the Installation Wizard. (Or double-click on the .exe file)
INSTALL them! ]

Drivers installed, close all windows, go back to your desktop screen.
Turn the computer off. Unplug from power. FOLLOW Anti-Static Precautions. Physically install the graphics card. Plug the monitor into the graphics card. Plug the computer back into power. WAIT 1 minute, turn the computer on.

I installed everything the CPU, RAM, and everything else. Connected all switches at the right places and the BIOS is on normal operation. I turn on the computer and its a blank screen nothing shows up....

ok, looking at the specifications All I can recommend is the following. double check the Video card to make sure it is properly seated and that it does not exceed the capabilities of the motherboard. 2 Disconnect everything from the motherboard except the CPU and case wiring/power supply and turn the computer on. If the system completes the post test, you will hear at least 1 beep and should hear several for the video card not being connected, then start installing components 1 at a time till you find the one causing the problem. Start with the Video card and then the ram as these are most likely where your problem is unless you have a faulty power supply which will be the problem if you don't get a completed post with nothing else connected.

My ASUS P5SD2-VM Is Having A No Display Problem

If you are using the motherboards built in VGA graphic display, check your bios settings. Open your manual to page 2-22. Read the page.
Make sure you have the bios set to, Primary Graphics Adapter [PCI-E] set to, [IntVGA].
Set the internal VGA to, [Enable]. You will also need to set an amount of your system memory for the VGA to use. It is recommended if you are using Windows Vista that you increase your 1GB of system memory to, 2GB. Or instead you can buy a decent PCI-E video card that will use its own memory instead of your system memory. If you do this you'll need to change the bios settings to, Primary Graphics Adapter [PCI-E].
Also change, Share Memory Size to [Disabled].
If you need the manual for the Asus P5SD2-VM. Click on the link below;

Click the dropdown menu & click on your operating system. Than click Search. Asus list all drivers, manuals, FAQ's ect.
To view the manual you'll need Adobe Reader. You can download Adobe for free at this link;

Again, if you do not have any display & your using the built in VGA graphics card try resetting the bios. Doing this will reset the bios back to normal default settings. The bios will auto use the built in VGA. To clear the bios see page 1-22.

Good luck!

Monitor shut off, no BIOS post, no keyboard or mouse lights, will not boot

The best thing to do in this situation is to build your machine outside of the case, using the minimum amount of hardware,
Remove the motherboard and using only one stick of ram, the monitor, keyboard and mouse. short the power switch connector on the motherboard with a screw driver for a fraction of a second just to power it on.
If it starts up and gives you a "no boot disk" or "no Operating System found" at least you will know it's working and you can slowly connect everything else one by one to see whats preventing it from booting.
If it doesn't start like that, remove the power cord from the power supply and remove the mother board battery for at least 15 minutes, this will clear the BIOS and set it back to factory spec, now carryout the out of case procedure already stated.

Video memory

1) On board video devices often use main system RAM,
by remapping it into their own address space.

This is designed to be CHEAP not GOOD.

Any RAM used by the video controller is NOT available to
to Windows, thus reducing system performance.

2) Sacrificing system RAM for video is a bad idea, the
system needs it more. Extra RAM in video controllers
is used mostly for 3-D effects and gaming, because
most video systems already have plenty of RAM for
implementing colors screen resolution.

On board video controllers are never fast or exotic enough
to benefit from the extra RAM anyway.

The rest of the system (i.e. Windows) on the other hand
can put any extra RAM to a far better use, by reducing
the need to store transient data on disk.

Don't forget that a hard disk is 10,000,000 times slower than
physical RAM, and when Windows starts running out of
physical RAM, it starts swapping data to disk (thrashing).

The performance penalty is not subtle !!!! Operations that
took a few seconds can take hours and even days.

3) It may be possible to change the balance between
system RAM and VIDEO RAM in the BIOS.
This depends on the motherboard.

4) If you want to drastically improve performance, do
buy a separate video card, for example an ATI Radeon
Saphire and disable the onboard video.

You must make sure the video card will fit in your
motherboard. Depending on the boards age, it
can use one of several types of I/O slots:

AGP 2x
AGP 4x/ 8x
PCI Express


The card must match the slot.

5) The suggestion that adding a separate video card would
somehow slow down your computer is absolute non-sense.

Tell the guy to read some books, take a few classes, and
keep his opinions to himself until he knows something.

Internal video cards (on-board) have limited capabilities,
and steal system resources. Add-on cards are designed
for performance, by adding resources and off-loading
graphics related computation from the main CPU,
allowing it to do 0ther things.

6) Finally, using the hard-drive to supplement video RAM
is impossible. The hard disk is way too slow. It would be
like hitching a snail in front of your Porche. Perhaps
even a little worse.

Video RAM needs to be extremely fast, even faster than
system RAM. It is often organized using ultra-wide buses
with interleaved addressing for maximum speed. Also,
for this reason, good video RAM is not cheap. A good
Video CARD will have between 256 to 512 MB of fast RAM.

If you run Windows XP, your system should have at between
1024 to 2048 MBytes of system physical RAM.

Less RAM will make your system drastically slower when
doing things like video and image processing.

For VISTA, two gigs is the absolute minimum.

Disk are used for storing lots of data at a slow speed,
and retaining it with the power OFF.

Hard disks can store about 1,000 times as much as
physical RAM, but the access time is up to 10 million
times slower:

RAM can be accessed in 1 nanosecond.
DISK takes 10 milliseconds.
