Question about Dell OptiPlex GX260 PC Desktop

Lost my audio, how do it get it back?

When you first turn on the computer, and press F2, to see the settings - I "accidentally" changed the IRQ settings, and lost my sound. Can someone point me in the right direction, or tell me what the right settings are?

Al encender mi ACER Aspire 5100 suenan 2 pitidos y en la pantalla me pone: Sistem BIOS Version:V3.13 Bus:06, Device:01, Function:00 ERROR Resource Conflict - PCI in slot 03 Bus 06, Device:04, Function...


You have a n IRQ conflict meaning you have a device that is trying to use an IRQ slot that its not meant to talk on. From the looks of it you have been in the bios already so go back in and set it to factory default.

10 reasons why PCs crash-You must know tip 3


3 BIOS settings

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.

A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).

Things You Must Know To Avoid PC Crash Part 1



Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."
You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?
1 Hardware conflict
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.
For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.
If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:
* Start-Settings-Control Panel-System-Device Manager.
Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.
Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.
Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).
When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.
To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.
2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.
But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.
One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.
Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.
EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

Default IRQ settings...


If you were just messing around with the keyboard, you have have just muted your audio output. You may even see in the lower right corner of your screen a red circle with a line through it over the volume control icon.
Laptop keyboards have function keys that let you mute your audio from the keyboard. Go into your control panel and click on the sounds icon, see if you have the mute box checked and uncheck it to un-mute your audio

I have asus mother board P5GZ-MX and the problem is i can't turn off the vga onboard on this motherboard....Please help me with the best solution...


Did you install the graphics card first, then try to install the drivers from the graphics card's CD? This
method is doomed to fail.
Why?
Because Windows 'sees' a new hardware device, and tries to match up one of it's generic drivers. There
wasn't any drivers installed from the CD, so Windows just found the next best thing.
The drivers CD should have been installed first, then the computer turned off, unplugged from power, and
the graphics card installed.
Now the monitor is installed to the graphics card, and you're on your way.
This bypasses the default setting of using the on-board VGA.

What to do now? Delete the software you have installed in your computer, and start over. (Start>Control
Panel>Add/Remove Programs>Graphics software>Remove)

Also you may want to see if an IRQ has been set for PCI VGA. (It's Plug n' Play or otherwise known as PnP)
Go into BIOS Setup, and set an IRQ for the PCI VGA (The term you'll see is -> Allocate IRQ to PCI VGA)
How?

Don't know if you've entered your BIOS Setup before. If so, disregard Number 1 below. (I'm not trying to insult your intelligence)
1.After you press the Power On button, the computer manufacturer logo screen will come up, (or instead
of a pre-built computer manufacturer name, it will be Asus. Computer manufacturer logo? Examples: Dell, Gateway, HP, and so on) Watch your monitor screen closely. As SOON as you see the logo splash screen,
start tapping the Delete key. Tap in 2 second intervals. You will now be in the BIOS Setup utility.

2.You're in the Main Menu. Look across at the headings. Second one over -> Advanced.
Press the Right Arrow key on your keyboard. Advanced will now be highlighted. Press the Enter key.
Now you're in the Advanced sub-menu.

3.See the ->Onboard Devices Configuration heading? 6th heading down. Use the Down Arrow key, and
highlight ->Onboard Devices Configuration Now press the Enter key.

4.See the ->Advanced PCI PnP Settings heading? Use the Down Arrow key to highlight it. Press the Enter
key. Now use the Down Arrow key and highlight -> Allocate IRQ to PCI VGA. Use the Right Arrow key to
highlight Yes, or No. Either Yes, or No, will be to the right. You want it to state Yes. Use the Minus key,
( - ), and Change Value. Change it to -> Yes
Now press the Enter key. Then press F10, and the y key. (It will look like a capital Y for clarity. You'll
be tempted to hold the shift key down, and press the y key. This = NO. Just press the y key. The y key is
for Yes. ->Yes you want to save changes)
Now press the Enter key.
Your computer will restart.

Want to disable onboard graphics to install and use pci vga card


During the initial boot sequence (as soon as you turn your PC on), try pressing <DEL> button (or F2 or F10 - you will see info on the bottom of the screen stating something like "Press _____ (del, F2, F10) to go to Setup..."

This will take you to BIOS, main setup panel for your PC.
There you can find and option for switching your main GFX card.
Options will be something like: onboard, pci, agp. You should choose
PCI.

Try doing this after you insert your new PCI gfx in your computer.


Good luck,

Edited boot config now computer beeps three times fans turn on high and screen stays black


Hi,

You can restore the "menu" of the "startup" to how it was before.

The idea is to reset the CMOS/BIOS to the original factory settings.  There are 2 ways of doing this:
1. Is to hit F2 again and look for Default Settings, click on that, save and exit; or
2. (Preferably), open your PC and look for the reset jumper (3 terminal with 2 shorted via a jumper). This is normally located very near the backup Lithium battery. Temporarily, move the jumper to the opposite pair and replace back to original position after a couple of seconds.

Hope this be of some help/idea. Post back how things turn up or should you need additional information..

Good luck and kind regards.
