Hi, have just treated myself to a new system and decided to build it myself. Have built a couple of systems before but a long time ago and p1 systems, big difference. System consists as follows: Item: Coolermaster Wavemaster TAC-T01 QTEC 550 Watt PSU P4 ready Twin Fan Retail Boxed Item: A7N8X Deluxe SKT A NForce2 Chipset Motherboard VER: 2.0 Item: AMD ATHLON XP2500+ 333MHZ FSB 512 L2 Cache Barton CPU OEM Item: Corsair (VS1GBKIT400) 1024MB (2X512) DDR400 PC3200 Memory Module Item: Coolermaster CP5-8JD1F-0L Upto XP3200+ Silent Skt A Heatsink & Fan Leadtek Winfast 5900 LX Item: Coolermaster 80mm Aero Blower Case Fan Item: Innovision EIO AP1600 ATA133 Controller Card Retail Box Item: Alps 1.44 Silver Floppy Drive 3.5 Inch Internal Oem 2 x Western Digital WD1200JD 120gb Serial ATA150 7200rpm 8mb Cache- OEM Item: High Quality Round Idecable Ata133 90cm In Blue Item: High Quality Round floppy Cable 60cm in Yellow Item: Usb Easy Access Keyboard/105 Key Carbonite/silver Item: Ebuyer 56K V.90 Hardware Fax/Modem - Retail Box I am now at my wits end with this, after many hours of configuring this and experiencing a multitude of probs (and ruining my xmas day), I thought I had it finally sorted. Now if I try to use it, I get a prompt that no keyboard is connected, but if I leave it for a while it gets past this and then proceeds to lock up partially into boot up. If I get to the stage of it loading the op sys, it comes up found new hardware and installs USB mouse and keyboard and then freezes. It seemed to me a heat issue, but after consulting the monitoringf software for this Mobo the temp is only at 32 deg and stable. Like I say it varies as to how far I can get the pc to operate for before freezing, yet yesterday I was running games with the CPU tenp rising to about 40 deg. Have tried disconnecting different cards but to no avail. Any help very much appreciated.
