GA-MA790XT-UD4P Keeps loseing hdd's dvd

[shane_uk]

Hi every one since yesterday afternoon since I first turned my pc on I've been having a strange problem were all four of my sata hdd's and dvd drive's keep disappearing in the bios. Every time I switch my pc on and off sometimes just my dvd will be there and not my hdd's or some of my hdd will be there and not my dvd drive. I have managed to boot in to the windows 7 disk a few times but it comes up with an i/o error saying to remove the problem drive which I have removed each drive one by one but still the same problem each time I turn the pc on sometimes the hdd's/ dvd will be there sometimes not. I have just replaced the bios battery but it's still the same. I am about to update the bios but I cannot see this fixing it as it has been fine for the last 6 months

Many thanks

Hi,

Could you post full system specs (CPU, GPU, Memory (type and brand), HDD's (details), PSU, Add-on cards, etc.

Are you Overclocking at all? Have you added any components recently?

The more info that you can post the easy it is to offer practical advice and help. 

Cheers

Hi,

I am about to update the bios but I cannot see this fixing it as it has been fine for the last 6 months

as a matter of interest have you updated your BIOS as you were going to?

You don't say if you are running your system in Native IDE, AHCI or RAID or which BIOS you are currently running, but the F7 BIOS looks as if it addresses an issue with the RAID/AHCI ROM.  It might be worth trying before you have to start pulling parts out to trace the problem.

F8C is a beta BIOS so might not be fully functional in all areas but if you are already at F7 the I would suggest giving it a go as you can always go back if it  doesn't work.

Here's the BIOS link: http://www.giga-byte.co.uk/Support/Motherboard/BIOS_Model.aspx?ProductID=3010 to save searching for it!

This seems familiar to me.
I believe it was a power supply fault last time this occurred, what was the reason for replacing the cd drive?

If your not running a Raid configeration Then set your bios to native IDE. this will solve you problems.
