Please help I'm tearing my hair out. My Pc is fairly new and it came with a automatic Bios update prog (can't remember the name). Anyway, it started telling me that a bios upgrade is available so I proceeded to download and install it. Before doing so I set a recovery point just in case.

After installation I restarted and now my PC won't boot up. All the lights come on as normal, but no signal is going out to my monitor. What's gone wrong and what can I do to correct it? Can I just remove the Bios battery to restore it to it's defaults? If so where can I find the battery on my mobo? Please help, I'm getting desperate.

The Mobo is a P4 Titan GA-81R533 series Intel 845 Chipset.

1st off.setting a restore point wont help you with a screwd bios flash.2nd.flashing bios within windows,is asking for trouble-which you now have.flashin bios,is not sometning done quickly,without knowing what you are doing.you have a gigabyte board by the sounds of it.all i could suggest,is take it to a comp store,have them reflash the bios
properly from the a\prompt,and turn off your auto upgrade bios crap

RJ is right, those windows based BIOS upgrade programs are trouble, they should be banned!

From another computer, go to the Motherboards manufacturers website and download a BIOS file and the Flash utility to use it. Then, follow the directions and let it create a bootable floppy with the BIOS program on it.

Then boot up your machine with the floppy in the A drive and follow the directions for reflashing the BIOS.

This is providing you feel confident enough to do this on your own, if not, do what RJ said and take it in somewhere. But by all means uninstall that Windows BIOS upgrade program.

Thanks for the prompt reply folks. I've taken out the bios battery (you're right, I can't miss it). I've put it back in and rebooted and still no joy. Blank screen on reboot. Have I just stuffed up my BIOS, or have I also trashed my hardware? Any other suggestions on what I can do?

How can I reflash the BIOS from a floppy if I can't see what's happening as there is no signal going to the monitor?

Yeah, that can be a problem:)

Still, go and check out the manufacturers website, some BIOS's like AMDs have a recovery system where you put the floppy with the BIOS in the drive and hold down a key, like F8 and it automatically forces a BIOS upgrade.

Check out the site and look for information on "recovering" from a bad BIOS upgrade.

Good luck!

Just a word for future referrance, If your computer is doing everything you want it to and runs fine ( dont flash bios ) Disable bios update software and if you desire check out he updates yourself at the website.

I wouldnt pull the battery out to reset the bios. If I wanted to clear the bios I would download the motherboard book for that motherboard at the manufactors website and read it and find the cmos jumper and use it to clear the bios, You run the risk of breaking something moving the battery. Easier and not as risky just using the cmos jumper. But as stated if your computer messed up during the bios flash, Clearing the memory of the cmos isnt going to do anything for you. I would restart the computer several times to see if it would do anything. By all means disable the autoupgrade if you ever get it going. Not neccesary to get all mobo bios upgrades.

Also, you're going to need to make a Win98 boot disk from a computer with win98 on it. You can also go to bootdisk.com and download one.

Here is a link to you MBs BIOS procedure:

I've found the 'Clear CMOS Jumper' which on my mobo is a set of 3 pins (not connected to anything). The manual and gigabytes website make no reference to how to reset it. Any advice?

Most of the time with three pins it is as follows,

Pull the plug from the wall and disconnect the power, Pull the jumper off the two pins its on and put it on the the middle and the other pin for a second or two and then pull it back off and put it back on. then plug computer back up and get your bios settings and go set all the settings in bios manually. After you clear the bios you will have to set the settings to what they should be accordingly. If you see anything on the screen.

The motherboard book does tell you what to do about clearing the cmos. That is not likely going to do a thing for you after what has happened.

Now that is strange. The three pins don't have any connector across them at all.

If there are NO pins, then the CMOS won't
hold whatever settings are in there. If there's never been pins, then that is weird!

However,
From what I can make out, if your new BIOS
has gone in properly, a jumper or a battery reset will still leave the new BIOS in there, it will simply reset all the settings to a 'safe' setting.

I take it the pc is shutting down rather than doing a complete boot up?
Are there any beeps?

I have had this problem on a couple of machines in the past, with two different requirements to fix them. You may or may not have similar problems?

1) when you reset to factory settings
things like CPU fan speed monitoring is activated. If you (or the builder) have put a bigger (and slower) fan on, the new settings may think "Hmm faulty fan, I'm switching off".
you would need to put the smaller fan back in the primary CPU fan connector and fool the monitoring system that it's ok. You then can get into your BIOS to unset fan monitoring. You can then remove the old fan.

2)you may have reset things like FSB to a point that your CPU or ram is wrong. (like 133 instead of 100?). However, a reset should put it to the lower setting, and it should boot....evidently not the case.

If you are getting no signal to the monitor but the PC IS completely booting, then I don't have an answer, other than to check all connections....which I'm sure you will have done,sorry.

KevH
