Hi guys, I have spent the last couple of days assembling components for my new PC. I managed to overcome some problems to a point where I install XP2 on the sata drive but when it reboots I get the following message. Sorry for the inconvenience blaa, blaa, blaa but windows came across an error possible owing to software or hardware change. It then gives you the usual options of; Start up in safe mode Start up command prompt Start up in safe mode network Start up normally I have tried all these options but the dreaded blue screen of death appears it reboots back to the above options!!! I am unable to read what the blue screen says as it quickly disappears. Okay this is the system I have built. Case: Coolermaster Stacker Operating System: Windows XP Home Edition Motherboard Features: ASUS A8V Deluxe Athlon 64 Mainboard - 2000MHz SB, Dual LAN, IEEE 1394, SATA Processor: AMD Athlon 64 FX 55 (939PIN) Memory: Corsair 1024Mb PC3200 DDR Memory 400MHz Floppy: 1.44MB Floppy Drive Hard Drives: Maxtor 300Gb Ultra Fast ATA Hard Drive & Raptor 74Gb 10000rpm ATA Video Card: 256MB nVIDIA GeForce BFG 6800 Ultra Optical Drives: NEC ND-3500A Dual Layer DVD-Re-Writable +R/-R/RW & SONY 16x DVD-ROM Drive Sound: Creative Soundblaster AUDIGY 2 ZS Platinum Internal 1) Firstly I am slightly confused with RAID. Do you need to have two identical hard disks for this to work of any of the formats (ie Performance, Mirror or combination of both). 2) Will RAID work on a single hard disk? 3) The mobo has both Sata RAID & just Sata connectors. It offers Promise RAID & VIARAID bios configurations but both can be RAID configured. I'm so confused!!! Putting aside the problem as above, what i'm after is for Raptor to be the main drive & the maxtor a slave drive. Now a breakdown I've what I've done so far. I have plugged the Sata hard disks into RAID1 & RAID2 on the mobo. I then choose a mirror array in the Promise bios options & reboot the PC. I then begin to install XP2 & press F6 to install the RAID drvier. It later prompts for the driver which I install. It also prompts for the RAPTOR hard disk driver which I install. It then reformats the drive in NTFS & begins to install XP2 right to the end. The PC reboots & the above problems occurs. I have tried playing with BIOS settings but that doesn't work. I assume the neither fdrive should appear as IDE primary & Secndary in the BIOS as they are SATA?? I want to use my new toy, somebody please help!!
