Anyone know how to fix this? I would run the test and about 5 seconds in my PC just reboots itself, I was under the impression that it has to take at least 15 minutes if you have a decent amount of RAM?

Memtest takes over two hours to complete on my desktop. Is your processor or memory overclocked? Are you running the memory timings tighter than default? I'd run through memtest with everything stock first and see if it still reboots. If it does then there's a problem.

As far as I know, Memtest runs a series of 10 different tests and then starts the series again. It should NEVER reboot until you intentionally stop the test. Something is amiss!

well since ur stress testing ur pc its given you a simple answer, somethings wrong. bad ram, psu is not strong enough etc. try testing again without video card for instance using only on board video to lower stress on psu,. then test one stick at a time. narrow down the possibilities one by one. even bertter if you have a friend and use some of his parts to verify what works and what doesnt. this is the sucky part of a self build.

I tried loading fail safe options and it still did that, loads up to 20%ish slowly then shoots up to 100% and reboots. I'm not even sure if my RAM is messed up, I got a few blue screens right after each other saying 'System_Service_Exception' and read about it and found out it might be from RAM, but after some testing I noticed that it was caused from overclocking my computer to 'Sports' mode. Ever since I loaded default settings from my motherboard I haven't gotten any blue screens.

another thing to check is what mode your USB settings are. I know a while back when I ran memtest on a newer system, i had to put the USB in Legacy mode i think. Otherwise the software would either lockup / say it had 1000's of errors / reboot my system.

What version of Memtest86 are you using? I experienced this very same rebooting thing when I was using Memtest86, latest version 3.5, with 2 x 2GB of G. Skill, on an Asus P5Q-Pro. Searching the Internet, I found a Memtest86 Wiki page that describes an incompatibility with 4GB of Ram.

I then tried Memtest86+ version 2.11, and it worked fine, recognized the P45 chipset, timings, everything. I ran it for 24 hours at full spec speed without errors.

The Memtest86 problem could just be 4GB on a P45 chipset. I tried the same program on my P5W-DH (975 chipset), which has 4GB of G. Skill as well, and it ran without incident.

I think the Memtest86+ is more up to date than the original and hence more compatible with modern hardware.

Good Luck
