    If the motherboard sees the ssd during post, you should be able to install and test windows on that machine, and that would determine if its the drive.

    Ugh, that reminded me to ask, is the SATA port you connected SSD in AHCI mode?

    I have a similar Sharkoon psu only 660W, good PSU but yours may be faulty in some way, I don't know for sure, only way to check is to try another known good PSU of similar power.
    The other BIOS reset I was talking about is close to battery, it's marked "JBAT1" you are supposed to take the jumper off and plug it on middle and left pin for 15 seconds and than return it in previous place. All of that with main power disconnected of course. Just one more tip for when you work on inside of computer, after you disconnect main power, press start button for a second or two, that discharges capacitors in PSU and MB and gets rid of any latent voltage left in them. If there's short time after you disconnected mains you may see fans turn on for a second, that's leftover electricity in capacitors, some of them in PSU are quite large.
    I found the JBAT1. The jumper is the black thing on/around the pins? It seems that it is already on the left and middle pin? So do you mean that I have to put it on the middle and right pin? Here's a picture, just to be sure:

    You would have to go in the bios to see if its in AHCI mode.

    Sorry, can't see it on that picture but....
    In the manual for your MB: MSI SRBIJA - Ra it should be like this:
    Click image for larger version
    And shows it being on right and middle pins But further down in the manual shows this:

    I did as it said in the last image you posted (took the jumper off, placed it in middle and right, waited, and then placed it back.
    When starting the pc, I didn't get any message saying the BIOS was reset, because it showed no signal again. But after a few restarts Windows loaded (no bios reset message) but froze after a couple of minutes of using it. I then entered the bios by restarting and pressing Delete button on keyboard, and looked for the SATA settings you asked for. I found this:

    SATA Configuration
    SATA Mode [IDE Mode]

    Since I did a CMOS reset today as well, I suppose IDE Mode is the standard? Do I have to change this? The options are: Disabled, IDE Mode, AHCI Mode, RAID Mode. But since you have mentioned AHCI, I suppose I have to change it to AHCI?

    For SSDs it's essential to be in AHCI mode.
    Tel me something, if you leave computer working with only BIOS showing, does it freeze after a while ?

    I haven't had it freeze in BIOS before, I think. I will change it to AHCI now. If this solves the problem, I would be so happy.
    But I haven't read anywhere that I had to change it to AHCI when I bought the SSD, weird.
    I also have a hard drive (besides the SSD). Does that one also work when SATA Mode is set to AHCI?

    Edit: problems are still there
    No signal, freezes and restarts when loading windows.
    I also ran into a BSOD for like half a second, then it restarted again. And I haven't seen a BSOD before.
    It just keeps restarting, freezing, and starting Automatic Repair, at which I click on Restart. Haven't been able to start Windows...
    When it looks like it is about to start Windows, the BSOD shows very shortly, saying "Your PC ran into..." with a big frowny face

    Edit: changing back to IDE Mode allows me to enter Windows once again. Changing that setting to AHCI made it even worse? Did I do it wrong?
    I can also make the hard drive my boot drive (put windows on there) and only use the SSD for programs. I don't know if that could help with the problems I'm having?

    Edit: I found out what the problem is regarding the BSOD by searching the internet. It appears I cannot just switch to AHCI, because the Operating System is already installed.
    I found this: "the problem is because the drivers loaded into the OS are expecting the boot disk to be IDE and they won't work with the disk switched to AHCI."
    and: "
    If you did not install AHCI drivers during OS install you have to manually install them and edit the registry in order for the drive to be recognized in AHCI mode."

    No, you didn't do it wrong this time but apparently windows were installed in IDE mode. To change to AHCI without reinstalling windows you have to do this:
    To change IDE to AHCI :

    1. Startup "Regedit
    2. Open HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlset / Services
    3. Open msahci
    4. In the right field left click on "start" and go to Modify
    5. In the value Data field enter "0" and click "ok"
    6. exit "Regedit"
    7. Reboot Rig and enter BIOS (hold "Delete" key while Booting

    Now change In your BIOS select SATA Mode to AHCI from IDE.

    You now boot into windows 7 or 8, the OS will recognize AHCI and install the devices. Now the system needs one more reboot and it should work in AHCI mode.
    After that you should check if Trim is enabled and Defragmentation for it is off.

    I can't seem to find msahci? I went in Regedit, and then HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlset / Services as you said, but there is no msahci there?
