SSD fried?

Hi folks,
I think I already know the answer to my question, but thought I'd ask just in case!

Windows was fine last night. Didn't install anything new or any updates. This evening it boots up fine, I goto make dinner and I come back to the boot screen announcing that I need to load the OS. I start in safe mode and windows freezes. Task manager won't load. I check Event Manager - nothing noticeable aside from the previous restart. I restart a couple of times hoping it will fix itself. No luck.
I load from the cd and it asks for me to install the OS. I run repair tool and get 'root cause found: the table does not have a valid system partition'. I try to restore from a back up (on a secondary hdd) and it doesn't recognise my original c drive (a ssd). Run the command prompt and open dusk part, which only recognises my back up drive and my dvd drive. I re-seat my ssd. Still nothing.

I'm assuming my ssd is fried. Does anybody have any alternative diagnosis?

Thanks, I'll try that tomorrow. Additional information: drive is not showing up in bios and I've switched sata and power cables around from working drives.

I found some time and tried partition wizard. When it was booting from the iso it timed out when attempting to secure a link to the sata drive as it couldn't connect to the attached device. When it skipped past that and past the resolution selection screen, the error message 'this bootable cd does not support windows server' pops up and restarts my machine. Am using windows seven, so that error seems a bit odd, especially as it can't read the drive with windows on anyway?

Ram, run memtest 86.
Remove all sticks but the lead one, closets to cpu, if you can't boot.

I've switched the sticks around and run memtest, and that came out fine. I keep thinking it might be the bios or the mobo, but a couple of times after restarts the disk is recognised, windows boots, then freezes (although the mouse still works).

Not sure what else to try!

start>control panel>system and securuity>system>advanced system settings>startup and recovery, settings>uncheck automatic start
If you can boot, next crash, it will stop at the BSOD screen giving you info that might tell yo something. You came back to a system that crashed and automatically rebooted giving you know immediate info.

start>run >type, msconfig>enter>boot tab> check safe boot, check network>apply> reboot

This will negate only but the most basic drivers. See if you can boot and see how long it runs. See if you can access the BSOD log if you can boot. You saw the log location when you unchecked auto restart.

Remove all drives connected but the SSD drive, should be in SATA port 0, and the cd rom, should be in SATA port 6.

You should fill out your system specs as well!

You should remove all sticks but 1, for now. Not juggle them around.

Your bios could be the issue BUT it was a functioning system, so.......
Try to reduce things to minimal so you can try and isolate the issue.
