Hello, I've got a PC here that's constantly restarting and I'm thinking the hard drive might be at fault but for the fact that diagnostics are saying it's fine.
Motherboard: MSI MS-7030
Memory: 2x PC3200 256MB modules, 3x available slots
Hard Drive: Western Digital Caviar WD1600JB, 160GB
Graphics: No on-board, 1x AGP (ATI Radeon 9600SE 128MB)
Power Supply: FSP Group FSP300-60PN (300W)
It starts up normally, and once it reaches the desktop it'll begin to show the Welcome screen, and then restarts itself. Disabling automatic restarts results in a BSOD with BAD_POOL_CALLER and the STOP codes of 0x000000C2 (0x00000043, 0xC38CA000, 0x00000000, 0x00000000). The same happens when I try to boot with Last Known Good Configuration, Safe Mode and VGA booting.
I tried booting the PC with all but the essentials powered up i.e. HDD, CPU fan and mobo with a single RAM module, none of which worked. I then tried the second RAM module swapped for the first, with the same results. To eliminate RAM as a possible fault I also tried another PC3200 module that I know is working fine, with the same results so I'm sure that the memory isn't at fault in this case.
I did some research on the BSOD and others suggested that it's related to either RAM or the HDD, and I was noticing a very loud click from the HDD every time it restarted, as if the drive head was skipping or something like that. This was followed by the sound of the drive powering down, and it promptly spins back up again once the POST begins. This supported the possiblity of an HDD fault so I unplugged the current HDD and plugged in an old 20GB one I had spare and installed Windows XP on it. Everything worked fine, tried several shut downs and restarts to be sure and it continued to boot fine, so I thought I had worked out what the problem was.
I downloaded Western Digital's HDD diagnostics boot CD and ran the full test from that with the original HDD plugged back in by itself, however it reported that the HDD has no errors. After restarting and trying to boot normally, the computer continued to restart. I used the Windows XP Recovery Console to run a full Checkdisk, which reportedly fixed unspecified errors however it continued to restart itself.
I also tried to run a repair install as another person had said their BAD_POOL_CALLER error was caused by a faulty XP SP3 upgrade, so I used an XP Home SP2 install CD to run a repair install, however halfway through the repair install the computer abruptly restarted.
So I'm back at square one with the added bonus of not being able to finish the repair install :-p any time I try to continue with it it just restarts halfway through. Has anyone had a problem like this before? I'm thinking of just slaving the drive, backing up the files and doing a full format and reinstall on it but I'd like some opinions before I go beyond the point of no return please.
Thanks for your time,
