Se riesci a controllare i log e a postarli si potrebbe trovare qualche info utile per capire dove sta il problema.

Il problema che descrivi di solito è causato da 2 possibili fattori.
1) Problemi al controller RAID (hang totale del sistema)
2) Banco di memoria difettoso di solito nei log vedi un errore che evidenzia la problematica

Come già indicato da LonelyWolf manda pure i log che gli diamo un occhiata

Ciao

Aggiornamento :
Hai letto questo advisor : http://downloadmirror.intel.com/19422/eng/TC_0040_ReleaseNotes.pdf

New Fixes/Features:
 Fixed issue where system hangs with POST code EB.
 Fixed issue where system has not video when using certain
graphics card.


Ciao

cavolo!!Non avevo letto questa cosa. Allora faccio anche un aggiornamento del bios sulla main!!!

Grazie!!!Vi faccio sapere

Salve,
purtroppo come scritto nel titolo il problema si ripresenta....
troverete la descrizione della macchina nel primo post.
In pratica succede saltuariamente che o al primo avvio dopo che la barra di riempimento ha terminato di completarsi, o mentre lavorano al gestionale , lo schermo del server diventa nero e il monitor dice che non ha più segnale!!Ovviamente i client sono sbattutti fuori, ma capita anche che come è successo Venerdì lo accendano e lavorino tuto il giorno senza nessun problema.
Quando il problema si verifica devono spegnere la macchina tenendo premuto il pulsante di accensione/spegnimento e al riavvio tutto ok, ne un messaggio di errore niente di niente...
Ho aggiornato il bios e sembrava che il problam si fosse risolto ,ma non è stato cosi.
Secondo voi la scheda madre può dare questo tipo di problema perchè magari non è tra le compatibili sul sito Intel?'
Ho fatto ache un check delle Ram ma è tutto a posto.
Cambio la sk video?Al momento usa quella onboard, metto una nvidia n8400 che ho qui in ufficio?
Comincio a pensare di dover rifarem il server.....
Help.

Grazie

Grazie della risposta,
a tuo avviso cambiando la Main con uno non identica ma stesso chipset vado incontro a problemi?
Ho in casa una MSI H55M-P31 , se la metto al posto della DH55TC intel faccio casino?

Se stanno cercando di risolvere via software quel tipo di problema potrei metterre una sk video , o sbaglio?

grazie

Ciao a mio avviso è un problema HW dovuto alla mother board.
Magari stanno cercando di risolvere via sw (vedi l'advisor) qualche problema di progettazione dell'HW e non sono ancora riusciti malgrado l'upgrade del bios.
Lavoro da anni e ti dico che capita più spesso di quanto non si credi. Apri una chiamata d'assistenza per la mother board e vedi cosa di ticono eventualmente la sostituisci con un altro modello di pari specifiche


Ciao

Sostituendo la mb non riscontri problemi a meno di non aver utilizzato raid hw e avendo tutte le dovute accortezze nello smontare rimontare il tutto. Per la scheda video ti direi di non aggiungerla al momento. Non credo che serva a dire la verità.

Ciao

Grazie ancora.
Un raid hardware c'è , ed è gestito da un controller Promise, non è gestito dalla main per intenderci.
Procedo?

Da come la vedo io ti conviene sempre fare un backup di tutto e poi procedere. Non si sà mai.



Ciao

Ciao, finalmente ho il log del crash di oggi:
