the problem began by my LAN card -which is built in- stop working and i lost my connection to internet so i bought a new LAN card and i installed it on one of my PCI slots ,so i began to have the net back after 1 week while i was surfing my computer give me this blue screen and reset when i reloged i found that my new LAN card is not defined by the windows ,and when i try to reinstall it the windows refused the windows identified the LAN card as "PCI DEVICE" before it was identified as "Ethernet device" i tried everything but nothing changed so i tried other cards in different pci slots and all are called "pci device" and did not want to be identified , after 2 weeks one of my friends came and press a button in my motherboard to reset the BIOS and everything went just fine i had the built in lan working and i could install the other lan card again ,that only last for 4 hours then the lan card in the pci slot go nuts again and refuse to be identified again i tried to re-identify iy but no use so i closed my computer and removed it and when i reopen my pc it start to make that whistle that repeated every time i open the pc and the pc never open just the damn whistle again and again, i removed the rams and the vga and reinstalled them in the motherboard and still having the whistle, then i removed a wire coming from the power supply to the motherboard not the big one but a small one between the processor and the powersupply the whistle stop but the pc also refused to open. wat shall ido???

الظاهر المشكله في الBIOS
اول شي تسويه, ركب الواير اللي فصلته, ضروري وجوده عشان يشتغل الجهاز
ثاني حاجه, شغل الجهاز بقطعه وحده من الرامات (اذا كان عندك اكثر من قطعه)
ادا توفر عندك جهاز ثاني, ركب كرت الشاشه, كرت الشبكه و الرامات عليه و تأكد انها تعمل
لان احتمال المشكله تكون من اي بطاقه او قطعة ذاكره, طالما ان المذربورد تصدر هذا الصوت

بعد ازالة الكرت من الكمبيوتر لم يعد يعمل معاك الجهاز ويعطيك صوت تصفير هل من الممكن اعرف كم عدد مرات التصفير لأن صوت الصفير له دلالة على القطعة التالفة ، بإنتظارك
