Dell Optiplex GX1 450Tbr+ failure at powerup

Hi,

I am tearing my head apart over this... :(

I was trying to fix a friend of mines computer (DELL Optiplex GX1 450Mhz) and it hangs at BIOS bootup. Just when under 25% of the progressbar is completed and it doesn't give any error message. The thing was that it was infected by a virus and I thought I would repair it by reinstalling the OS.

I have tried the following:

- Several restarts, same thing.
- Lifted out and put in the CPU (with nescessary reboots inbetween)
- Lifted out the memory, one by one, with restarts
- Disconnected the HDD and CDRom
- Lifted out the battery to reset bios (it worked one time, but at next restart it hanged at the same location)
- Lifted out and changed the jumpers on the mainboard.

Does anybody have any more ideas? cause I don't.... =(

The strange thing was that once when I was testing it, it worked and booted up, but when I pressed the reset button (beacuse I wanted it to boot from the cd) it hanged at the same place. Bios revision is A07 and the computer is from sep 1999.

Thanks in advance...

There are a number of things that could cause this:
- a bad installation cd (make a copy and try it with that)
- bad RAM (download and run diagnostic program from www.memtest86.com)
- a bad hard disk - run the diagnostic program for your hard drive:

Also, try replacing the CMOS battery, since it worked once and the motherboard is pretty old.

When you talk about a progress bar, you are beyond the BIOS.  Or did you mean something else?

I tried replacing the CMOS battery, thats what I meant before...

I cant run any diagnostics since I don't get past the bios bootup - it doesn't matter whether the HDD or CDRom is connected to the motherboard or not, it still hangs at the same location...

Is the drive detected properly by the BIOS?  If it isn't, you may have a jumper or cabling problem.  To determine if it is your IDE controller, try it with another drive.

and there is a normal bootup-sound from the HDD if it's connected....

without any memory it beeps.
without a CPU it doesn't start.

there aren't any additional ISA or PCI cards to remove. Everything is integrated on the motherboard.

and as I wrote earlier,, with pretty much everything else it freezes during BIOS bootup...

That's right, so is that the message you get if you disconnect the hard disk completely?  If it's connected, it locks up before Windows starts?

yes, it locks up at BIOS bootup, before it initalizes the harddrive. I am not even able to get into the BIOS.

I would say your drive is faulty and needs to be replaced.  As soon as the system tries to communicate on the IDE channel, it hangs.  Put a brand new IDE drive in it's place and I think you will see a different response.

I'll try that, but shouldn't it start when I removed the HDD and run without anything connected to the IDE?

Yes, I did ask you about that in the 04/14/2004 04:53PM EST post.  Are you saying it doesn't go to the floppy if you remove the hard drive?  If you've got it set to boot from the floppy and the hard disk isn't connected and it hangs, you have a problem with your IDE controller.

I guess there isn't a way to change the IDE controller without replacing the motherboard?

Well, there is - you can install a PCI IDE controller card that will do everything the motherboard IDE does: http://www.newegg.com/app/ViewProductDesc.asp?description=16-102-002&depa=1
