  1. Hi. I have a serious problem with my computer and badly need help.
    I have a customised desktop. I had it assembled at the store i bought the parts from. Now the problem is that my monitor does not display anything on the LCD and the PC switches on just fine. The monitor shows only 1 thing: "No Signal" My specs are: a asus m4a79t deluxe mb, amd phenom II 955 be(black edition), thermaltake 700W pwr supply, thermaltake V9 case, G skill ram 4gb, 500gb WD HDD, LG Disk drive, and lastly, a acer P235H monitor.
    i have checked all the wires inside and outside. All of them seem to be plugged in just fine. i have used this desktop for almost a year now and this is the first time m facing such a problem. Oh, and 1 more thing, my keyboard is wireless(logitech) and when press the num lock ket it lights on the censor but when i press the caps lock key, it doesnt have any effect.
    Please help me!

    Try checking the pins on the VGA slot on the back of pc they might be a bent pin.

    As for the keyboard and mouse first thing to check is the batteries then try reinstalling the software for the keyboard and mouse and check that is upto date.

    Hi. Thank you very much for replying.
    But you see, the problem is no with the batteries, see, if i press the num lock it works but if i press the caps lock, it doesnt. So i guess there is absolutely no problem with the batteries. As for the VGA, i'm using a DVI-VGA converter thing and that seems to be fine too. Any ohter reason this might be happening??

    Your graphics card may have failed. Can you try another in its place or can you try your card in another PC?

    Ok. But do I have to install any CD to make my graphics card run in my friend's PC?? And how can i tell if my hard drive crashed or not. I think that could also be the problem right??

    Hey, i remembered something, umm.. a few days before i had the problem, my PC used to get stuck very often while i was playing GTA 4. It would just get stuck on one scene and the audio would go off then i had to restart the PC and it was working fine after that then the nesxt day i played GTA 4 again, the same problem occured. Does this prove that my graphics card was facing BSOD?? Blue Screen Of Death??

    It depends on whether you're are trying to run the same brand of GPU, ATI or Nvidia. If it's different, you should uninstall the old graphics driver before installing the new card. I would use the latest driver found at the ATI/AMD or Nvidia website.

    I'm not sure I understand your BSOD question. Did you get a BSOD?

    Hey Guys, thanks a lot for the help. I have found out the problem. It was regarding my RAM i just had to pull it out and start it and then install it and start it again. I was told of this solution by a friend but he did not know the cause of this thing and how removing and reinstalling the RAM would fix the error. Do you know what might have gone wrong?

    The RAM might be faulty.

    I would be running your RAM on memtest overnight to make sure its error free.

    sounds like a possible power supply issue

    OK, ArjunDhanak212 , sounds like you have possible faults with your memory and may be the hard drive as well, there are other things that can cause slow boot times but first I would run both these tests to be sure it is not a hardware problem then you can look for other causes like bad drivers or malware.

    Reseating the memory may have just proved that you had a bad connection it would not have cured faulty RAM. Just to be sure it is seated correctly follow the first part of the guide to clean the sticks, also do this with your graphics card, if you have one.

    Sounds like you also have a faulty keyboard, try to borrow one for a while and see if has any effect.
