Hi im new to these forums but please could somebody help me with a problem that has developed in my machine.

I run a :

2.8Gig p4 800mhz fsb ht cpu on an abit IS7-e mobo
512mb ddr400 ram all in one chip with heatsinks installed
Gecube ATI radeon 9600 pro 256mb
400w power supply
3 hdds : 160gig maxtor sata (split into 3 partitions, 1 is c: )
40gig maxtor ide (slave, 1 partition)
40gig unknown drive (master, 1 partition)
cdrw rom
dvd rom
Win xp home (when problem started was sp2)

I recently read an article about overheating in computers and how this can deteriorate the life of a computer significantly. Therefore i thought to myself that i should order a new case, with extra cooling measures that could be installed. I did this and bought a spacewarrior case from vusys i transferred all the contents of my machine carefully across and it worked perfectly so i decided to improve the cooling and bought in some 12cm fans to make sure there was air being drawn in through the fron and being expelled properly from the rear. I installed the fans very carefully and made sure i didnt touch anything that i didnt need.
When i next turned the pc on it didnt boot and a message came up saying bootdisk failure insert system disk and press enter. So i looked in the bios to see if anything had changed and nothing had. I hve had problems with ide cables before so even though i hadnt touched the ide cable since i last had seen it working i changed it out thinking that maybe that was causing it. No effect still the same problem. checked all the connections to the hdds power supply ram all i could think of, still no change. so i used my win xp disc to repair the installation, no luck, but i could get to the desktop but if i restarted the computer myself then the same problem would appear even if i was loading from the cd drive first.
I next tried to reformat the drive earlier today still no luck as itcomes up with the same error that i earlier experienced if i changed boot priorities back to hdd first. however it now will boot as long as i have the win xp disc in the drive and set it to boot from cd first.

Can anyone help please.

Just to be sure I understand you correctly, your old box worked, you transferred the internals to the new box and it still worked, you installed the fans and it stopped booting from the OS hard drive at that point but all drives are visible in BIOS.

OK, if you disconnect the fans does it make a difference? I suspect not but try it anyway. If it does and it all works again then I'm not sure why but let's not question too hard. But if, as I suspect, the same problem is there now whether the fans are connected or not, you must have dislodged something or grounded something while installing the fans.

In that case, I would thoroughly check all the connections and ensure the motherboard is not dislodged or otherwise touching where it shouldn't. Consider pulling it out and re-doing the job.

Are all your drives mounted in the same order as in the old box? If not, I assume you've checked all your master/slave assignments.

Hope you'll pardon my ignorance but you have five drives [3hdds + cdrw+dvd] - how does the connection set up work? Do you have a RAID array or something?

i tried taking out the fans no change. recently i purchased a new drive a 160gig sata hdd i installed this and made 3 partitions on it, this has become my primary drive as my other 2 are ide and the first (which used to be my primary is an old 5400 rpm model) but i have 5 drives because i am using a sata hdd as all ide ports have been filled. The drives are mounted exactly the same as they used to be because i didnt wnt windows telling me that my comp isnt same an wanting a reinstall. tried different ide cables but as the primary hdd isnt on ide but on sata i didnt make any differeance.

yup it shows up right at the start when the comp checks devices and it also shows up in bios.
Just because a drive is listed during bootup and on the main BIOS screen doesn't mean it is a bootable device. You need to enter your BIOS settings and look for the boot options where it should tell you which devices it will look at to find an operating system and what order to check them in (it will boot off the first bootable device it finds in the list). Your SATA drive might be perfectly good and properly identified by the BIOS but if the BIOS doesn't look at that drive when it searches for boot devices then it won't happen.

Yup one of the partitions on my sata drive is my primary drive and it is plugged straight onto the mobo.

im pretty sure that the hdd is the primary hdd it looks for, at least it used to be because i had no problems before. Also when i enter which hdds it looks for when booting option one is look for bootable hdd but it also lists the rest of the hdds as well.

OK, if we're certain your SATA drive is a bootable drive and the BIOS looks for it then time to look at other options.

You mentioned the PC will boot with the XP CD in the drive so to me it still points to something awry with the way your drives are set up, either misconfiguration or something dislodged when you installed the fans. The PC worked when you first changed cases so we know it should be able to work now.

How much disassembly did you have to do to install the fans? Was the mobo taken out of the case again?

Have you tried disconnecting all but the SATA drive and attempting to boot from there? Try to minimise the number of things that have to work and see if it will boot. If it does, try adding the other drives in sequence until it stops. Windows won't mind as long as the boot drive is the same.

To install the fans i didnt have to remove or even touch any components i did however have to move the case downstairs as it is easier to work down there. The mobo was left in the case and not touched. it will boot with the win xp cd in either drive.

Thanks for your help labman.

could it possibly be a mechanical error with the disk as i have noticed lately that it has begun to make a loud vibrating noise now and when i listen it is coming from the drive, and it is barely a month in my possesion.
