PC randomly freezes briefly and then reboots

[Mathiaslp]

Hey folks

So, after I've installed my Crucial m4 128GB ssd, and installed OS on it (Windows 7 Ultimate x64), I get these reboots.

First the computer freezes for a sec, then the picture on the screen breaks up into "lines" vertically, and then the computer reboots. When booting up it asks me if I wanna start in safe mode etc.

It happens randomly, but after I installed my SSD.

I have the latest firmware (0009), the 0309 dosnt change anything execpt BSOD after 5xxx hours, and I havnt used my SSD for more than 72 hours yet.

Installed motherboard drivers etc, windows drivers, gfx drivers.

Help please?

Unfortunate thing with SSDs is that if you have to suddenly reboot, you can't really trust your OS anymore.

Flash has to errase a block before it can write to it.
Block sizes are generally larger than the data you're writing.
Wear levelling means that data gets scatterd across the drive, and critical data could be anywhere, even next to the cat videos you're currently downloading.

Because the cat video is being saved, blocks are being cached, errased, modified in memory, and re-written.
Those blocks, because of wear leveling, could also have some of your OS files.
If you hard-reset, after an erase, but before the write, you might have just lost a chunk of your OS. Who knows what you lost...

All in all, it could be your SSD, it could be a sata cable.
It could be unrelated to storage, and just happened to be at the same time as a drive change.
Or it was an unlucky hiccup, where you had to restart, and the restart damaged your OS and you're forever gonna be messed up until you reload it.

This is why SSDs with capacitor backups should be used for a critical computer's OS drive.

Also, vertical lines would make me suspect your video card...
I would run an experiment, and see if it happens with a different card.

OS HDD going offline usually appear as :

1) Applications and interface stops responding, but mouse keeps responding.

2) A few moments later, one of 3 things :
a) Frozen system. Non responsive. Screen just stuck in place, appears normal otherwise.
b) BSOD
c) Sudden black screen followed by a POST (reboot).

Generally, there isn't any kind of special graphical artifacting.
You can boot up and unplug your OS SSD on purpose, just to see what it looks like.

The vertical lines sound like a video issue, possibly with a new driver version that you've loaded since you did your SSD OS install, at least that would be my guess.

I would take the time to just put anything into your system that is not your current video card (and don't use the same driver, install something else), just to check.
It's worth the few minutes of effort just to swap the hardware and verify - just to know.
If it's not video related at all, then great. One less thing to worry about.

You can also test your SSD by going back to booting your old HDD, and just using the SSD as a second drive for games/programs.
That way you can use the SSD in a non-critical scenario.
If the SSD is bad, ~all programs/games will have issues with crashing.
