Ok my computer is crashed, it was running great, then all the sudden it crashed.
Here's the details,
I have a home built computer with the following components:

Windows 7 64 bit Home Premium OEM system builder pack
MSI 890GXM-G65 mainboard
AMD Phenom II x6 1055T Thuban 2.8 Ghz Processor
MEM 2Gx2 - OCZ OCZ3G1333LV4GK.NE.R Memory
2 Super Talent 32Gb solid state drives SATA
1 older 30 Gb Hard disk
DVD Drive
USB Keyboard and Mouse

Here's what happened:
I was runing RAID 0 with the two identical solid state drives wich contained the system files. (blazing speed)
I was using the older Hard disk for data.
I was making a playable DVD with win 7 DVD creator, and the system seemed to be working exceptionaly hard.. alot of drive action going on..
I then recieved an error stating the Drive space was low on my solid state raid drives, then boom all went black.

I am aware that I have lost the data on the suicide raid drives, I can live with that.
I now want to do a clean install, without the raid configuration using one of the SSD drives for the system.

Heres the problem,
when I boot the system, it auto detects everthing fine, and then hangs at CMOS checksum bad press f1 for setup or f2 for default values. or press f11 for boot menu.

Everytime I change the BIOS it keeps reverting back to this error.

I have got it to boot from the CD drive but it hangs after the splash screen
I cannot get into the recovery or install program, just the BIOS.

Any Ideas whats going on here? Thanks

RocketSurgeon,

Welcome to HTG.

Disconnect ALL devices except (1) SSD and the DVD.

Clear CMOS to include removing the battery for 3 minutes.

Manually Reset up ALL Bios settings and save.

Raise the Memory volts to 1.8V and manually set the Timings plus save.

Since this will leave you nothing to boot up to, set boot sequence to DVD First and save.

With O/S disc installed, See if you can get to a Command Prompt on Install Halt in Win 7 without a Bios error.

Wow, this seems to be working. I did eveything you said except raising the memory volts, and it worked. I tried the BIOS reset and battery before, but I did not disconect everything while doing it. I am reinstalling to my SSD (no RAID) this time. Thank you.

RocketSurgeon,

Great !!!!

Most memory modules are not stable at 1.5 Volts under heavy load NO matter what the manufacturer states so be sure to set the memory voltage at 1.7 Volts OR this could happen again.

Raid was not your issue.

Hey Rick,
Thanks for the advice, but I cant seem to find the menu in my BIOS for raising the memory voltage to 1.8V. As far as the crash goes -
I believe I had a SSD drive failure in the RAID 0 configuration. I was able to reload the O.S. to one of the drives and restart the computer and I don't really notice a difference between the RAID 0 and using a single SSD config. (The system still boots from a cold boot in about 15 seconds). But, the system does not recognise the other SSD. I've tried swaping the SATA cables and power cables from one drive to the other but i still get the same results. So I guess im in the market for a new SSD , or possibly regular hard drive. I like gaming so I think I want to go with SSD but games really take up alot of space.
Any suggestions?

RocketSurgeon,

May just need to prepare the SSD again.

Disconnect ALL devices except the [ Bad ] SSD and the DVD.

To prepare SSD using Windows Installation DVD, Boot and Start Win7 Installation.

At First Halt, Press (SHIFT + F10) for a Command Prompt.

Type in Commands below and press ENTER Key as follows:

DiskPart <ENTER>

list disk <ENTER>

select disk 0 <ENTER>

clean all <ENTER> [ Will take a while as is a Wipe ]

create partition primary align 1024 <ENTER>

format fs=ntfs <ENTER> [ Will take a while as is Full Format ]

active <ENTER>

exit <ENTER>

exit <ENTER>

Cancel Install and Reboot.

See if the drive is recognized now ????
-------
If so, DO the SAME above to the Good SSD.

Now you can put them both back in Raid 0 Array and install the the O/S.

Thanks for all your help, the system up and running great, all drives working.
I'm not using the RAID 0 configuration though the risks seem to outweigh the advantages. I'm still trying to raise the mem voltage to 1.8V in BIOS.

Great !!!!

Glad you got the SSDs fixed. Was just a matter of preparing the array drives after the failure as I thought. :)

You all well on your way to becoming a Builder. :) :)

Best Regards,
Rick P.
