EX58-UD3R often loses connection to drives.

[Z Overlord]

So I have rev. 1.6 and using the latest non-beta Bios. My CPU is an i7 920 @ 3.9GHz (stable, ran linX, memtest86, and Prime95 for long time, no errors).

I have a OCZ 128GB SSD, a 2TB HDD, a DVD drive, and a BD drive.

My issue is that my PC once in a while freezes, and then I must reboot, often for my PC to say there is no drive connected, and to please insert local disk blah blah blah.

I have tried replacing the sataII cables and switch channels. Today for example it detected none of my drives in the Bios.

What should I do? What can I do to confirm these issues?

Hi

What ports are yopur hard drives connected to ? It is possible the ports or the controller is failing. Of course it could be the drive as well. Is your primary drive a "Green" version ?

[Z Overlord]

Nah no green. I plugged them into the blue ports (which is most of them).

Anyway to determine what is the issue?

[Dark Mantis]

By the sound of it you have them connected to the correct ports.

What mode are they running in ?

Are all the drives SATA ?

Have you flashed the SSD to the latest firmware ?

[Z Overlord]

IDE mode for all (recommended by OCZ), there is one later flash but it doesn't fix it.

[Z Overlord]

Yes. SataII.

Often it happens while I'm using my PC, so it's like things start getting slow and then eventually everything freezes but my mouse (it eventually freezes too).

Also I doubt it's my SSD because of this thread I made a while back:

In that case try opening Resource Monitor and see if you can watch as the system slows down to see what is hogging all the resources.

Ok I'll try, but usually it happens pretty fast.

What do you mean by "It happens pretty fast" ? I thought that the system was grinding to a halt so to speak.

[Z Overlord]

Well the "grinding" process happens quickly, like it only lags for a bits then freezes.

So today I scanned my PC with the Microsoft Standalone System Sweeper (a bootable virus scanner CD). When I came back it had an error saying the service had stopped. I reboot, go into bios, and my SSD is not detected, my other drives are. Of course I couldn't boot.

I shut off the PC, wait a minute, then turn it on it's all detected and boots.

Could is be the SSD then? I wish I could figure this out 

[Dark Mantis]

That is just what I was thinking. Try disconnecting the SSD and see if everything returns to normal use. You can find out if there is any newer firmware for your drive that you could flash it with.
