Hello everyone....

I have a very clean, well-running XP (home) machine. Well...it WAS running.

specs: ATX K7N2 delta series Mo-board. .From memory I think the BIOS are phoenix, but am not certain.

Anyway, I booted into the BIOS yesterday and made a change to the BIOS to overclock. Made changes according to the manual. Rebooted and nothing. I am not sure if the machine is even going thru a full POST. I tried putting the windows CD in, but it isn't 'taking' it. Is there a way to clear the BIOS thru a jumper setting on the main board? My luck....first time I try and experiment with overclocking.

As it is now the machine is dead....no boot, no screen, maybe even no POST.

Of course I cannot locate the rescue disk. Is it possible to make one from a similar machine to at least get to a prompt? Would this even help?

Anyone have any suggestions?


Thanks

Can you get to BIOS? If you can, enter the BIOS at start-up and change the settings back to what they were, or set one of the default options that have names such as Load Fail-Safe Defaults and Load Optimised Defaults, both of which should remove any settings the user has enabled or disabled, and enable the system to boot.
You could also try pulling the cmos battery out (if you can't get into BIOS or even if you can and the above doesn't work), leave it out for about an hour, reinstall the battery, resetting the time and date, and then praying that it works to get your computer running.

No, I can't get to anything, but I forgot about taking the battery out. That's just nutty enough to work. That reminds me, isn't there jumpers you can cross to also clear the BIOS to default settings? seems there is.......not sure tho.

I took the battery out, so I'll leave it out fort a few hours and see if that helps.

Thank you for your input.

Make sure that the computer is unplugged from the wall. Some will maintain their settings if the battery dies.

Thanks for adding the part I forgot to mention.

Look in your mobo manual for info about the jumpers.

Here's an update.

I had the battery out for several hours......I DID find in the manual (I guess I must have missed it before) that there is a clear BIOS jumper. I tried it in every conceivable configuration.....with battery in, out, plugged in and unplugged....no difference....and no change. the computer is still in the same condition as it was.

Anyone have any other ideas please?

:thumbsup:

Fix, One thing you may want to make sure of and that is to check all connections. This includes the Keyboard. If you attempt to boot with these disconnected your BIOS will not respond and thus you get no boot up.

Next at this point you have nothing to lose try this.

Disconnect everything.
Take your battery out, undo your cables, Memory Sticks Card. Everything that you can think of remove. DO NOT REMOVE ANYTHING YOU ARE UNSURE ABOUT.

While you are there clean the PC out of Dust.
Look at your Cables, see if they looked burned or damaged. Instead of putting back a gig of memory only put back a single stick.

Post back and let us know if anything happens. Also do you hear the computer beep
Does it at least have Power

Thank you Jitaa :thumbsup:

If you try everything the people are suggesting and there's no improvement, you can possibly replace the BIOS chip BIOSman inc. I've used them in the past when I've trash a BIOS so bad nothing worked. Just remember EPROM's are like CPU's their pins bend easily.

Disconnect everything that you can (with the exceptions listed here: http://www.bleepingcomputer.com/forums/t/70216/hardware-troubleshooting-via-system-stripdown/ ) and see if you can get it to boot.

Don't forget to check the caps for bulging - that can cause this sort of behavior. ( http://www.badcaps.net )

Here's another update:

It's fixed. I found the manual (it's a pain finding stuff after a move), and took a chance on changing a jumper on the mo board. This fixed the problem and I think also overclocked the processor in the process. I haven't explored that part yet, but at least it's working.

So you all know.....I did find and tried using the jumper designated for clearing the BIOS. I don't know if it worked or not but it didn't get my computer running, so I'm not sure what's up with that. I tried this with the battery out and the plug removed from the box. So......like I said I don't know if this actually accomplished clearing the BIOS and there was some other problem going on the other jumper fixed I don't know, but at least the thing seems to be running nicely now.

Thank you all for your ideas and input and suggestions! I appreciate it a great deal.

Hope you all have a good week.


:thumbsup:
