Odd loss of drives in BIOS

[grn]

Hi All,

Finally got my new system up and running WIndows 7 Professional and it has been running perfectly for a few days now.

The system is:

         1. Cooler Master HAF-X case
         2. X58A-UD3R motherboard
         3. 3x4GB Crucial memory modules
         4. Zalman Utlra Quiet CPU cooler
         5. Intel i7-950 CPU
         6. XFX P1-850B-NLG9 PSU

The graphics card I am using is temporary (I'm awaiting the card I want) - it is a Gigabyte GeForce 8400 GS.

However, today I had an odd problem. I was working on my PC and stopped for dinner. About an hour later I came back and the system was sitting at the BIOS stage, displaying the BIOS splash page and did not boot. It had tried both CDs for a boot system (but there weren't). I thought something had happened to my boot disk, so put in the Windows DVD and tried again but the same result. Saw the two CD drives but didn't try yo boot. Rebooted and entered the BIOS to discover than none of the 3 SATA drives I have in were showing. Switched the system off and left it for about 30 minutes, retried and lo and behold the disks now show.

It was very strange as the CD drives are SATA and they showed up in the BIOS. Needless to say, it is all working now but I'd be interested in hearing if anybody has any explanation for this. Could there be a fault on the motherboard?

Many thanks

Hi and welcome to the Gigabyte Forum.

What disks are they that you are running and on what ports?

What have you got the controllers set up for IDE or AHCI?

Thanks for the speedy response. The 3 drives are:

Samsung SV100 64GB SSD
Western Digital Caviar WD10EADS 1TB
Seagate Barracuda ST3500418AS 500GB

The SATA channels are set to IDE.

Let me know if you need any other information

Which ports are they on?

[grn]

The drives are on 0, 1 and 2. I know that the SSD drive is on port 0, and I think the barracuda is on port 1 with the WD on port 2. The CD drives are on ports 3 and 5.

Ok as long as the controllers are set to IDE that should be fine.

Have you tried clearing the CMOS completely and then loading the Optimised BIOS Default settings? If you haven't follow these instructions:


Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least ten minutes before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Opimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self and then press F10 to save and exit.
