    Hey everyone,

    Sorry for the dramatic title but this problem really is actually making me go a little mad.

    My system had intermittent issues where it wouldn't load, about a year ago. Sometimes it would post, sometimes it wouldn't. Then, after a while, it stopped posting at all. What would happen is the graphics card fans would spin to maximum speed, and I would get one long beep followed by three short ones - no VGA detected. I assumed it was my graphics card and returned it. After an extremely long and unnecessary replacement procedure, I got a new graphics card, which worked for a while before the same problem occurred - it stopped booting at all, just giving me the "No VGA Detected" beep sequence.

    So, I thought it must be the motherboard. I returned it and sure enough the test result said that there were problems posting. I have now received the replacement AND IT STILL DOESN'T WORK!!!

    I do not have another system I can use for parts but I was able to check it with a basic PCI-e card from a friendly computer repair shop and that DID work.

    So that indicates it's the graphics card.

    But if it's the graphics card, why did the system work for a while (about 3 weeks) before starting to fail to boot? I never saw any artifacts or anything on screen. Furthermore, if the graphic card is the problem, why did the motherboard come up with a fault?

    I am thinking I'm cursed. The motherboard comes up faulty - but then the new motherboard won't load with my graphics card, itself a replacement. What is the problem here? I have ordered a new graphics card (#3) and will return the current one (#2) if it does work...but what could be causing the issue in the first place? It's a new mobo, and a card that worked for a while - it seems that it would be fantastically bad luck to have two graphics cards which both break over time AND a defective motherboard.

    I'm lost. Any thoughts, anyone, please - I am desperate.
