I get a blue screen error after instaling drivers for this card. I ******* can't stand it annymore. I get IRQ_NOT_LESS_OR_EQUAL blue screen. I tried every possible driver for this card and it just won't...

An IRQ fault message is not a driver issue, but is a main board fault. Try clearing the CMOS memory (remove the coin battery and short the battery holder contacts together, then re-insert battery). System should start back up with default settings in the bios. Check the settings and re-boot. If problem remains, then the main board is bad.

Manual reset motherboard: Soyo SY-K7VME

Bios settings are retained by the Motherboard Battery in the CMOS. Disconnecting the battery clears CMOS and returns the settings to their original state. Typically this can be done by simply removing the CMOS battery and waiting about 15 seconds before reinserting and booting PC. Nowadays most Motherboard manufacturers supply a jumper to not only disconnect the battery but also ground the CMOS to effectively drain any residual power.

The instructions for your MB are found below. JP5 is located to the left of the battery and next to the PCI 2 slot on your MB. There is a Manual for your MB on this site and the MB layout can be found at

Follow the steps below to clear the CMOS memory.

1. Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JP5. Its white cap can easily identify this jumper.

2. Put the jumper back to 1-2 to allow writing of new data into the CMOS memory.

I need to reset the bios password on my metrobook ltplus

At his time you need to open the back cover of you laptop to solve the problem. You need to reset the CMOS battery of jamper to clear BIOS password. To open the back cover you need to remove first the laptop battery after that fine and remove some screw.
Once you have already remove the screw and the cover you can see there a small circle CMOS battery you need to remove is to clear all stored password in CMOS memory. You can also see there a jamper near the CMOS battery just remove that and turn on your laptop with in 10 seconds and turn off. Reinsert the jamper with the same position.
Now the CMOS password are already clear just turn on your laptop first before you close the cover.

Soundcard keeps dying


A couple of things you can try:
  • change PCI slot location id not built-in, is an add-on;
  • ensure the IRQ assigned to the sound card is not shared with any other device(s);
  • check your CMOS/BIOS settings.
  • update your drivers.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

New asus m3n72-d motherboard bios will not post

If you don't already have a case speaker hooked up to the board, you might want to connect one since there isn't an on board speaker and you will not hear error beeps otherwise.

Also, if you have another non-phenom AM2 processor handy you should really update the BIOS to latest release. Many late model Phenoms will not work on motherboards that have earlier BIOS releases and you will not be able to post. You should then choose "Set Optimized Defaults" and save the bios without any changes then shut down (not reset). When you power on again it should post and you should be able to get into the BIOS.

A third thing you can try (after you get a case speaker hooked up) is using a cheap pair of ddr2-6400 RAM to get the board to post so you can get into BIOS and change the voltage to the correct settings for your RAM if it requires a higher voltage than the bios expects.

Need to reset bios password for acer 4620 laptop. tryed removing battery on mb . no good . ? passmord bios

Try removing the main battery and the CMOS battery (ie the battery on the mb). If you don't want to wait for 1/2 hour for the CMOS to discharge then short out the CMOS battery connections with a bent paper clip.
Then without instralling both battery, power up your laptop, you should then get into the BIOS, power off and re-install your batteries.

No display at post

There are a few things that can cause no display on the monitor.
That single beep means POST = Power On Self Test. Post has tested everything on you're board to be good.
The cable between video card & monitor may be bad or not connected correctly (Swap out the cable as last resort).
2. You're monitor is defective, try swapping it with known working monitor.
3. You're video card is not functioning.
Lastly, when you reset the system cmos/bios everything went back to default. This means you're bios is now using the onboard PCI video graphics. Remove you're radeon 9600 video card. Try booting the system. You should see display again. The only way to test you're radeon would be to boot to the bios & set bios to boot using the AGP radeon. You need to change Init Display First to AGP & not PCI. If you loose video than you know you're AGP card is bad. Reset the cmos/bios before adding another AGP card or you will not get display. This setting is on pg 3-5. Integrated Peripherals. If you need you're manual you can download it from this link:

Good Luck!

Iwill w100 usb drivers


Being a socket 370, perhaps you need to enable the USB ports in the CMOS/BIOS first before the motherboard can detect them and then the OS to request/install the necessary drivers.

You would of course need the CD that came with the motherboard to install the appropriate drives.

If they are enabled in the CMOS/BIOS but yet are not displayed in the Device Manager, you may have either an IRQ conflict or a hardware fault.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
