Help figuring out problem

[sabwafare2001]

My question is what might have caused this to happen just in case it happens again. The story is below
Here's my setup:
Athlon 1800+
Gigabyte GA-7VRXP
Volcano 7+
Kingston pc2700 512mb
80gb Maxtor Diamond Plus 9-7200rpm
80gb WD800JB
100gb WD1000JB
ATI 9500 Pro
Samsung cdrw 48x16x48
Samsung dvd drive 16x
600W Powmax

Had this setup running without a problem for about six months until this morning when my computer just restarted as if it crashed. I have my both of my samsung's drives hooked up to IDE1 and my 80gb hard drives to IDE2 and the 100gb on IDE3. Nothing is overclocked and hasn't been and everything is running at stock speeds. I didn't know what it was doing before this because I was sleep, the beeping sound it made from when it restarted woke me up.

Here's what I saw, on the screen where it detects your drives, none where detected. I pushed F1 to resume, then the next screen came up whee it reconizes the drives on IDE 3&4 or your Raid setup, and reconzed the 100gb hd. The next screen was where it looked for a device to boot up from. I have windows XP installed on both drives on IDE2, but niether of them didn't get reconized. So I reset it and it reconized the samsung drives only. It went through the same procedure as above, so I reset again. I decided to go into the BIOS and detect the drives and it worked and now it works like normal.

My system temp is 40C and CPU is 39C. I had a similar problem where the hd on IDE2 didn't get reconized even when I put them on separate channels. I took off the jumpers the hd and they worked perfectly. When I had them on cable select they worked for a short time and then wasn't reconized when I started it up one day. Cause it reconizes the drive at the end of the cable as master and in the middle the slave weather its on cable select or with no jumpers. But now I don't have any jumpers on my hd's so I'm wondering what happened????

Well first of I would put jumpers on all your HDD, and set them to master/slave.
Second I would flash the BIOS, might not fix anything but it can't really hurt, plus you got your old one on the 2ndare BIOS so you can always go back.
Then I read somewhere that you should never have any optical drives on IDE 3 and 4. Not sure about this, you should do some reading up on it, or E-mail gigabyte.
It might have been a glitch that made it restart like that, it happens, no code is perfect and memory errors do happen.
As to why it wouldn't detect your drives, well some comps are very finicky, and like to be very anoying before they start to work properly. I would say don't worry about it for now, and see if it happens again, then you can start to troubleshoot. Its hard to do so if it only happend once.

Yeah the reason for me not having any jumpers on them was that the drives didn't get reconized at all when they were on the same channel another drive was, Optical or ATA, whhen I had jumpers on (master,slave or cable select). When I got these drives, the 2 80gig, they worked with the jumpers on for only a couple of times, then I read somewhere that these drives act funny about that, the jumpers.

Interesting.
I would still flash your BIOS to the newest one, than read up on the whole optical drives and IDE 3&4 issue.
It may be true, or not, but if it solves some problems, or prevents new ones from coming up its worth that e-mail or reading throught the FAQ or manual.
