    Good day everyone! So a few days ago my desktop computer started restarting for no reason (no bsod or any other errors). Then I stopped the computer so it can "rest" over the night. At the morning, when I tried to start it, it wouldn't start. http://www.youtube.com/watch?v=T7-vd73d2XQ&feature=youtu.be This is what was happening. Then, after cleaning up the whole computer case, every little fan and making sure that everything is in place (the cables in my computer case are really messed up though), the computer started. But the monitor didn't. It just didn't recognize the computer. So I left it like that for some time. Then I noticed that there is a second VGA slot in the back of the PC and plugged the monitor cable there. It worked, but I guess it was an onboard card or something. In Preferences it was recognized as "Default Monitor". So I couldn't play any game and the resolution was bad. [Could only watch movies and browsing. So I thought that I can just watch movies for the rest of my life. Or wait until we can get the computer to an IT specialist. Well, due to some issues, I can't get the computer to anyone. So I thought that you guys might be able to help me out?] So I was browsing the internet, when suddenly a wild BSOD appeared in front of me. I thought that I should just restart the computer and it'll work. Well, it didn't work. The monitor would go "No video input, etc. etc." like the cable is not plugged into the computer. This happened two days ago, since then I haven't had the chance to use it. I've tried with both VGA slots, nothing happens. Sometimes the computer would boot normally (the monitor wouldn't work though), next time it would start for 1 second, like I've shown you in the video, then the fans stop, boots again for 1 seconds, everything stops, keeps on going until the world ends. Well, that's basically all that's to it. Here is some information on the PC:

    CPU: Intel Dual Core E2200 2x2.2GHz
    RAM: 3072 MB (3GB) DDRII
    HDD: 500 GB SATA II
    VGA: GF 9500GT 512MB DDRII, PCI-EX DVI/TVO


    I've had problems with the motherboard before, I think it's a hardware problem now as well. Monitor should be 100% fine and working with other computers. I hope that you guys can help me out, I would really appreciate it. Much love :3

    what are you running
    video card brand and model
    cpu
    m/board
    ram
    power supply
    brand
    model
    wattage

    if you can access the bios

    check the listings in the bios for 12v line voltages and temperatures and post them

    video card: nvidia geforce 9500 gt
    cpu: intel dual core e2200 2x2.2gb
    mobo: Biostar G31-M7 TE
    power supply
    brand: rexpower?
    model: atx12v
    wattage: not sure how to check
    I dunno about those watts/volts, but it says 230V at the back, next to the power switch.

    Can't access bios, pc turns on for 1 second atm. Sometimes it wouldn't detect monitor, like I said. Tried removing the bios battery and putting it back in place, tried with 1 stick of ram, tried with the other one, both. Nothing really happens. I also took the video card out and plugged it back in, nothing happens. Tried both VGA slots on the back. It used to work with the one that's not connected to the video card, but it stopped working after some time. Everything's screwed. :D

    to get the onboard to work remove the actual card

    take the side off the case and look at the label on the psu

    Power Supply could be bad, could also be motherboard. How much memory do you have in the system? How many sticks or memory do you have? If you have more than one stick of memory, try removing one, and booting...if that doesnt work try switching them. If it doesn't turn on after that..then I would look into either the CPU, Power Supply, or Motherboard that has gone bad.

    Dunno, it's my second power supply on this computer, it have worked for a year. Memory is 3GB.

    I SWITCHED RAM STICKS AND THE PC WORKED! But monitor still won't work. :S

    btw something started to smell like burning and the button that I use to start the pc's light doesn't glow anymore. Guess it passed away.

    Generally when you smell something burning or burnt in your computer that is not a good sign. Open the side of your computer and try and see where the smell is coming from. Also put your nose near the power supply and smell. Make sure everything is plugged in tightly...reseat the video card also. If you can boot from the onboard video, then try and get into the BIOS and look for video settings...sometimes if you have onboard video on the motherboard, if defaulted to the onboard, the PCI-E videocard wont post. If there is a setting in the BIOS for that, then change it from the onboard video and test again.

    I can't really sense the smell now, not really sure where it was coming from. All I know is the PC boots normally, but no video. Reseated the video card like 10 times, tried both VGA slots, nothing really happens. Can't get into BIOS since there is no video on the monitor.

    It wont boot off of onboard video? From what I gather you have the onboard video and a seperate video card right? could you take a straight on shot of your motherboard and a shot of the rear of the computer case and post it? This may give me a little more insight of your system.

    The computer will always boot, but the video on the monitor doesn't work. It doesn't work with the onboard video card, nor does it with the other one. Not sure what pictures should I take? I already have posted some in my previous posts.

    Take a shot of the side so we can see the whole inside of the computer. Then take a picture of the rear of the PC where you plug everything in.

    psu's not lasting usually means low quality and underpowered units are being used
