This is my system: MSI KT6V-LSR AMD Athlon XP 3200+ 1 x 256MB Elixir PC3200 DDR ATI Radeon 6500 32MB DDR Hitachi Deskstar 7K250 160 GB SATA HDD DVD-ROM CD-RW 2 case fans Thermaltake Volcano 11+ CPU Fan/Heatsink Standard 300w PSU (Came with the case) Windows XP Pro SP2 I have been having some issues with my SATA drive cutting out. There are a bunch of entries in the Event Log that say "The device, \Device\Scsi\viamraid1, did not respond withing the timeout period." and then "An error was detected on device \Device\Harddisk0\D during a paging operation." Eventually this leads to a bluescreen error which I have read about and determined that it's caused by the hard drive being unavailable for a page file operation or something of the sort. So for some reason either my HDD is cutting out or the VIA SATA controller is cutting out. Sometimes when I turn on my computer is doesn't recognize the sata drive and fails to boot but by rebooting a couple times it recognizes the drive. When I run chkdsk or the hitachi hard drive tools sometimes it locks up before completing and other times it runs through the whole process and reports that the drive is fine. I have also noticed that the voltage readings from my PSU are consistently low, for example the Vcore is 1.6, the 3.3v voltage is 3.17, the 5v voltage is 4.92, and the 12v voltage is 11.4. Also, this issue may or may not be related: my CPU shows as a 3000+ instead of a 3200+ when I boot up the system even though the FSB is still 400mhz and the CPU is running at 2.21Ghz. Could my problem be that I have a PSU that is possibly not providing the power that my system needs? Any help with these issues would be greatly appreciated.
