Motherboard FRIED???

By bscman ·
I "inhereted" a newer generation Hewlett Packard Pavilion from my aunt after an incident which has supposedly fried the motherboard.
She was online, and assuming atacked by a virus, her computer went dead.
I have gotten the computer to turn on, but claims "No Operating System"
The HD is still good, I have also tried using a different drive to no avail.
A boot disk is of no use, because for some reason the CD Drive is "Not Available/Not Connected/Already in Use"
The light on the drive works, however it will not open and close. It is as though the only functioning piece is the Diskette Drive.
I am also able to access Bios.
If anyone has any thoughts/ideas/plans of attack for me, please let me know.
It claims not to find any drives other than A
Thanks,
Brett

A virus would not act this drastically,so you may be looking at computer failure
Sounds as though there was a power surge or a spike
Does the Power Supply fan spins upon startup?
This also should apply to the CPU
If you can boot into the CMOS panel for bios configuration check the configuration main menu
Set hard drive to AUTO
set the boot first to Hard Drive,A:,CD-ROM
eject floppy and reboot
Now try with Floppy in A:/driveand boot computer
choose to run setup without cd-rom support
eject floppy and reboot
Once you determine whether this will work or not
Insert floppy and type FDISK /MBR,now type in SYS C:

Well the motherboard isn't fried or it wouldn't be booting. The "no operating system" tells me that the system is trying to read the drive, but there's something preventing it. I suspect that it's not seeing the drive geometry right, whether via the internal IDE or some sort of bios helper (although I don't remember HP ever using those)

I'd just go get a couple of new IDE cables and a external controller and change the cables first and see if that helps, and then install the controller with the HD and CD-Rom

For what's it's worth, I remember some of the HPs I worked on usually only supported one channel on the IDE devices. You may end up formatting and reinstalling, which doesn't sound like a big deal to you since you're already talking recovery CD.

Good luck to you

Hi,

If you dont mind re-building the PC, check in the BIOS for whether the PC is set to boot from the CD or not.

If it isnt' enable it. I usually go for the following boot order : A:,CD,HD so I can boot from either the floppy drive or CD if I need to.

The fact that the CD door wont open could be a bunch of things. Can you open it at all? Ever? If you cant open it immediately after powering the whole thing on, then it could be a problem with the drive.

Boot to DOS then try.

I havea CD drive (its an older one) that has worn out the mechanism and frequently jams. But the CD door wont open until its not being used and the boot locks it during its hardware discovery anyway.

The others have made good suggestions too...so follow them.

Good luck,
Cheers,
Tim.

I suggest you visit the HP web site and find out how to reset the BIOS for the particular model you have.

Variations in power, including a failing power supply can scramble the BIOS settings of a computer. As stated, the motherboard does not sounds like it is burned out. Otherwise, you would not POST.

Once you have cleared (reset) the BIOS, you need to enter the BIOS utility and set the time, date, hard drive specs, as well as any otehr special settings specific to the PC you are using. If you need further assistance, please feel free to contact me.

Do you see that little itty bitty hole on the front of the CD? That is there to enable manual opening of the CD. Just insert a paper clip and while pushing in the paper clip gently pry open the CD tray (Computer power off!). If it wont give then themechanism is jammed and a new CD is in order. If you can open it and close it this may free it up to work normally. Also virus IS a good possibility. Some Virii will erase your hard drive and may even lock up activation of your CD through a small program ( I think this is a slim chance though). You need to re-format your drive with the boot disc and re-install the OS.

what the fellow below (user deleted) is saying is that the designers and manufacturers of the computers deliberately added a fuse at great expense knowing that it would do no good because the cicuit it protects blows in microseconds but the fuse blows in milleseconds! What bunk!
