Ive just rebuilt my HCPC system using the following components:- Mobo Abit AN7 SATA, µGuru nForce2 Ultra400/MCP2-T Case Accent HT-400S Graphics Sapphire Radeon 9600 XT Ultimate 128MB Hard Disk Seagate Barracuda 7200.7 SATA 160Gig CPU AMD Athlon Barton XP3200+ 400FSB - OEM Memory GeIL 512MB (2x256MB) PC3200 Golden Dragon CAS2 CPU Cooler Samurai P4/AMD XP/AMD 64 Case Fan Zalman ZM-F1 Ultra-Quiet Case Fan PSU SilenX 400w <14dBA Pro iXtrema PSU Dlink DWL-G520 54g wireless network card Nebula DigiTV card When I record to the drive I get interference lines every time the drive is accessed. If I to a defrag, I cant make out the image on the screen the interference is so bad! Has anyone else come across this problem and how do I solve it? Is it a faulty drive as this sort of RF interference shouldnt happen with a CE marked device? Cheers, David.
