hp compaq de7700 small form factor

Recommended Posts

Am primit acest pc HP COMPAQ DE7700 SMALL FORM FACTOR,cu defectul,la pornire se invart ventilatoarele pentru cinci decunde,dar in acest timp se aude un carait la procesor,dupa care se oprste caraitul si ventilatoarele,si se aude cate patru bipuri la interval de 3,4 secunde ciclul de bipuri se repet,pana ajunge la 20 de bipuri in total,iar ledul din fata de la pc se aprinde si se stinge continu,rami buni,procesor bun,sursa buna,ce sa mai verific,rest de bios am facut,va rog.

De unde stii tu ca sunt bune...le-ai verificat in alta parte? Daca le-ai verificat in alta parte inseamna ca e placa de baza stricata (singura ramasa),posibil cineva sa-i fi facut un update haotic.De obicei asa se intampla..

Uitate la pini in soclu la procesor,sa nu fie vreunul plecat.

Canta feritele (bobinele/miezuri) pe alimentari la cpu.Ori cpu e mort,ori c-uri terminate/ori sursa stricata (c-uri umflate in sursa) ori integratul care comanda alimentarea pe cpu stricat,ori etc etc.

Acum,sunt destule calculatoare care functioneaza binemersi cu acel tiuit,unele pleaca din fabrica..nu e o regula .

 

Primul lucru care se inspecteaza e sursa,asta pentru oricine,inainte de a porni pc-ul.De bun simt,ca sa nu avariezi mai departe.
