I need help from the brain trust trying to get this XP rig working. I have run out of ideas and keep getting this same bluescreen. The internet says its memory related BUT I have run Memtest for like 15hrs straight with zero issues. Is there a bios setting causing this?

System Specs
Windows XP 32bit + Windows 10 64Bit
Intel Core i5 750
8GB Kingston DDR3 1600 ( 2x4GB )
Gigabyte P55-USB3 motherboard on 10j bios
GTX Titan 6GB
Sound Blaster X-Fi PCI card
USB3 card
Crucial 1TB HDD in dual boot

What I have tried to fix this on the XP install ( haven't re-done the W10 install yet )
- Updated all drivers and bios
- Disabled HPET
- Disabled onboard USB3
- Disabled onboard sound
- Tested ram with MemTest over night (15 passes)
- Tested 16,8,4,2GB ram combos
- Disabled Paged Memory in advanced system settings
- Disabled all onboard devices
- removed usb3 card and removed soundcard

What is not effected
- I can run 3DMark 2001SE and 2006 no issues ( should rule out the GPU )
- Can run the heaven benchmark no issues

What ALWAYS triggers the bluescreen
- Attempting to load Everest Home Edition
- Attempting to load system overview in SoftSandra
