Memory card: Be certain that your memory card sits well in its slot.
Improper fixing of the memory cargs brings about the incomplete booting of your system.
When booting, it displays the ROM data and starts the POH POH POH  sound.
Resolution: Shut down the system, open the casing and make sure that you have no metal or any conductor on you when working on the mother board which is the house of the RAM to avoid any electrostatic force flowing to the board and condemning the board.
Remove the end keys holding the RAM down and replace it firmly from ends making sure you hear the two sides making a clicking sound.
The sound shows that the Ram is well seated.
Cover the system with the casing and restart your system, It must work now.

    تضغط على زر تشغيل الكمبيوتر فيعمل ولكن الشاشة تظل سوداء اللون!قبل البدء في محاولة حل أية مشكلة من الأفضل دائماً النظر إلى الأسباب البسيطة ومن ثم الانتقال بالتدريج نحو المعقدة.
فإذا واجهتك مثل هذه المشكلة: شاشة سوداء بعد تشغيل الكمبيوتر، فأول ما ينبغي عليك القيام به هو التأكد من أن وصلة الطاقة ووصلة البيانات الخاصتين بالشاشة موصولتين بشكل صحيح ومحكم في المنافذ والمخارج الخاصة بهما.
ومن ثم تحقق من كون بطاقة العرض موصولة بشكل صحيح ومثبتة بإحكام في المنفذ الخاص بها على اللوحة الأم، سواء أكان PCI أو AGP.
ويفضل إزالة بطاقة العرض وتثبتها مرة أخرى.بعد التأكد من كل ذلك حاول إعادة تشغيل الجهاز مرة أخرى.
إذا ظلت المشكلة قائمة، فلا بد أن مردها أحد الأجهزة الموجودة في الكمبيوتر لديك، كالمودم أو بطاقة الصوت أو الذاكرة أو ما إلى ذلك.
فكر بآخر شيء قمت به قبل حدوث هذه المشكلة، هل قمت بإضافة جديد إلى جهازك فقد يكون سبب المشكلة، بكونه معطلا أو غير مثبت بصورة صحيحة.
قم بإزالة الجهاز ثم حاول تشغيل الكمبيوتر من جديد.

Power Cords - Make sure that all of the power cords are firmly in place on all of the devices that could possibly be causing or attributing to the symptoms you are experiencing (i.e.
If nothing shows up on the monitor make sure that the cords are attached to both the monitor and the computer itself).
Then trace the cords back to the wall and make sure that the other end of the cord is attached to a power outlet or surge protector.
