PowerMac G5 DP 1.8 GHz Late 2003: si blocca o non si accende

[dany.nero]

Salve a tutti,
ho un PowerMac G5 DP 1.8 GHz del 2003: a volte la macchina non parte, e il led frontale lampeggia 3 volte.
Ho provato a cambiare i banchi RAM (Perfettamente funzionanti e testati con memtest su una macchina X86).
Tenendo premuto il tasto di accensione per piu di 10 secondi la macchina emette un suono e poi successivamente parte.
L'Hardware test, effettuato con il disco ASD 2.5.8 di Apple mi conferma che è tutto regolare.
Oggi sono riuscito a farlo accendere ed è andato in Kernel Panic (a volte rimane bloccato senza alcun messaggio di errore)
ecco cosa riporta il log

Grazie a tutti coloro che potranno aiutarmi

Prova un reset PRAM e NVRAM

[dany.nero]

Gia tentato... Purtroppo a volte si accende ma non va proprio.
Oppure parte e dopo poco si blocca o va in kernel panic.

[fragrua]

Penso che qualche microsaldatura sia passata a vita migliore, forse non per forza sulla scheda logica. Chissà magari provando un'altra scheda grafica?

[dany.nero]

Grazie per avermi risposto.
Le schede grafiche dell'ultima serie di Power Mac G5 (late 2005) sono compatibili con lo slot AGP di questa macchina?
Vorrei fare un tentativo con una scheda che posso procurarmi a giorni.

[Simone.m]

Appena mi connetto con un computer ti linko una guida che dovrebbe risolvere il problema. Devi fare il reballing di una parte della scheda logica

Franz mi hai anticipato!

Perfetto ragazzi! Grazie per la dritta... provo a fare il reballing!
