Chiedo aiuto a quanti riesono a risolvermi questo problema. Il pc (pentium4 3Ghz, 2 gb di RAM, scheda video Radeon 3850 hd da 1gb, MB Asus P5GPL-X SE) con SO Windows xp Pro sp2, va a scatti. Ogni volta che utilizzo un programma, musica e video si vedono a scatti e si impalla. nel task Manager la CPU è quai sempre oltre l'80%. leggendo i vari forum, pare potrebbe essere causato da un virus. ho fatto scansioni con ogni tipo di antivirus, antispyware, ma niente. come posso risolvere questo problema?

non è che qualche ventola si è rotta?? succede ed i sintomi sono quelli controlla che quella dell'alimentatore giri ed anche quella del processore

[gi_bu]

no, penso proprio di no. ho rimesso una scheda video che avevo prima (radeon x300,x500 da 256mb) e tutto funziona bene. potrebbe essere difettosa la scheda video? o non è compatibile col processore o con la MB?

[grifone1900]

quando hai montato quella da 1gb di ram i driver te l'ha chiesti??

nella descrizione hai messo 2 mb di ram penso che ci sia un'errore....

[gi_bu]

la scheda video è da 1 gb, la RAM da 2. comunque ha richiesto i driver che ho scaricato dal sito ATI. mah, per ora ho risolto, mi rode per i soldi spesi per la scheda video!

[grifone1900]

un suo cd non ce l'hai??

[gi_bu]

ho il cd della confezione, ma era una vecchia versione e mi dava dei problemi. ho scaricato una nuova versione dal sito. non è che poichè la scheda video è una ddr3 non è compatibile? o bisogna impostare qualcosa anche nel bios?

[grifone1900]

i problemi erano gli stessi??

sulla scatola ci sono i requisiti minimi controlla che il tuo pc ce l'abbia
