Sorry how do I watch the bios flash? It does it through the windows xp not booting the computer. When it finishes then it requires a boot. Thanks

Unless you are still experiencing a problem with this computer, I would not recommend flashing the BIOS chip.

If you are still experiencing a problem and need to flash your BIOS chip, I want to warn you, doing a bad flash can lead to a non-bootable computer.

Special instructions need to be followed and one thing to keep in mind.....Do not restart or turn off the computer until the flash program prompts you to do so!

There are more details to offer, however unless you plan to perform a flash of your motherboards BIOS chip EPROM, there is no point in going into further details.

Bruce.

Well it did work but xp keeps telling me when it restarts it was missing registry parts but it did finds the missing parts & tells me that about 4 times before XP finally is loaded. Other than that I don't see a problem.

I dont think your BIOS would cause registry errors. There is no reason to flash the BIOS at all unless you are experiencing problems that the BIOS can affect, registry is software related and the BIOS does not affect your operating system software for the most part. If the computer is running fine and stable under the current BIOS theres no need to update it. Doing a system restore however, may fix your registry. It should be under system tools.

Yes. But I just noticed that my password when it boots up is gone again. That is the one you set up in the bios. I wonder what else is going on? This has disappeared a couple of times now.

When you flashed your BIOS chip did you follow the instructions carefully?

In most cases, after a successful flash is performed, you are asked to boot the system and enter the BIOS setup utility again and choose one of several different worded options. I list the wording below.

Load system defaults.

Load best configuration.

load defaults.

Load fail safe defaults.

Load setup defaults.

These are usually offered in the main menu where the navigation keys are displayed on the screen.

Some computer manufacturers recommend moving a jumper on the board to clear the CMOS, this is done after the CMOS battery is removed to avoid shorting out the battery.

Your system time and date will be reset to the system default and will need to be set back the the correct time and date.

You should check to see if those are even correct now. Your CMOS battery could also be weak or dead.

One more addition to what I posted above, none of the changes you make to the BIOS will save automatically, you have to make the changes, then press the F10 key on the keyboard, a dialog box should appear asking if you want to save the changes and exit, you have to confirm those changes by typing Y for yes.

Thanks just checked my time is bang on. If memory servers me I replaced the bios battery last year. The bios update was done with asus update in windows. Not through a bios flash on a cd or floppy.

Perhaps another format & new install again with this new power supply?

To post my 2 cents here about power supplies and video cards.

The most important thing to remember is to look at the amount of amps on the +12 volt rail(s), and look at the requirement for the video card.

My GTX 480 I just got requires 42amps on the 12 volt rail. My power supply supplies 60 amps on my single 12 volt rail. I have enough to spare. I also have a total of 750 Watt PCP&P Power Supply.

If you feel you need to do another install, that is totally up to you.

I am not going to advise against it, because you could be on the right track here.

You should also concider the advice cryptodan posted above, he seems to be pretty knowlegeable about PSU's as well. :thumbsup:

Thanks...remember I am an electrician. Perhaps cryptodan has some number wrong. 42 AMPS & 65 AMPS would be a small transformer weighing about 500lbs. Perhaps it's watts? Not really possible in a small cpu. :thumbsup:

I see what you are trying to say BUT current is current at any voltage. They can spec what ever they want but max input current is 12 amps. Which runs on a 15 amp circuit. Did you see any #6 or #8 conductors in your power supply? I didn't in my 900Watt. Im not knocking it, it just can't be. Plus they have admitted it's ONLY 80% efficient. Ohms law doesn't lie. These are NOT step up transformers. I don't know how they can claim what they do but simply electrical laws prove other wise. Another way to look at it is you would have a fire if it indeed it pulls 45 & 65 amps. 16 gauge wire does not carry that much current without burning.
