I did a complete rehaul of my PC about 4 months ago and I've been experiencing all types of BSOD's and random system crashes. The crashes are usually a lockup that results in my audio replaying like a broken record and occasionally a completely random restart (without BSOD). The crashes do not occur just when I play games. A few weeks back, when I'd boot up Windows, it would find new Hardware (PCI Device). I tried reinstalling Mobo Drivers and it fixed the problem but it actually increased the frequency of the BSODs and crashes. I also had problems updating my BIOS when I originally installed my mobo. It wouldn't allow my PC to boot into Windows unless I used the default BIOs. Here are the errors I find in event manager (starting from most recent): The Application Layer Gateway Service service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. Timeout (30000 milliseconds) waiting for the Application Layer Gateway Service service to connect. Error code 1000007f, parameter1 00000008, parameter2 bab38d70, parameter3 00000000, parameter4 00000000. The HTTP SSL service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. Timeout (30000 milliseconds) waiting for the HTTP SSL service to connect. Error code 10000050, parameter1 812c313a, parameter2 00000008, parameter3 80540a24, parameter4 00000000. The Application Management service terminated with the following error: The specified module could not be found.

Error code 1000008e, parameter1 c0000005, parameter2 bfa7eca8, parameter3 b3b12a64, parameter4 00000000. I've tried reinstalling mobo drivers, graphics drivers and sound card drivers. I've tried running Windows Memory Diagnostic with multiple passes, but it shows no faulty memory, however when I send error report to Microsoft, it says that it suspects faulty RAM. My system specs are as follows: Microsoft Windows XP Home Edition Version 2002 SP2 Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz 1.87GHz, 2.00 GB of RAM Intel Core 2 Duo E6300 Conroe 1.86GHz LGA 775 65W Dual-Core Processor EVGA 320-P2-N815-AR GeForce 8800GTS Superclocked 320MB 320-bit GDDR PCI Express x16 HDCP Ready SLI Supported Video Card ASUS P5N-E SLI LGA 775 NVIDIA nForce 650i SLI ATX Intel Motherboard CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400 Linksys Wired Gigabit Network Adapter Linksys Wireless-G 2.4 GHz Router Motorola SBS101 SURFBoard Cable Modem Mad Dog MegaSTOR 16x Triple Format DVD Burner Comp-USA 16x DVD-ROM Drive Creative Soundblaster X-Fi XtremeMusic Soundcard Can't tell you the power supply model off hand, but its 600w and appears to be running smooth. I also use three different internal hard drives...2 Seagates and a Maxtor. OS is running on a Seagate. I have dual boot Vista/XP with XP on as my main OS. Crashes also occur when running on Vista with minimal software installed (just Norton Internet Security, NOD32, Deamon Tools, keyboard drivers, mouse drivers, video and sound drivers, etc.) 4 most recent Minidumps are attached to this thread, along with a copy of DxDiag.txt.
