Ive built a new computer and ever since day one I've been getting error 124. It started off less frequent but has siginificantly risen over time. I have done numerious test and replacements. So far I have replaced the RAM and Motherboard as I believed they were the culprit turns out it wasn't I dont think its harddrive or software problem as I have reinstalled windows 7 64 bit numerous times on different drives. My computer will blue within five minutes of starting prime95 on large or blend torture test but will not restart on small test which leads me to believe the CPU is fine. Out of frustration i took it to a computer shop and they deemed that the GPU was the culprit as it had been water damage by humidity. It was a valid reason but if I take the graphics card out and do test again it will still blue screen within five minutes.
