I am a computer technician and am having terrible troubles with a new custom built computer. Sometimes it will POST... sometimes not. It typically powers up but whether it will POST and send video signal is a crap shoot. I bought a DIY kit from Newegg, built it up for a customer and everything worked fine with no troubles. I then bought that same kit and built it up for another customer. Then the problems started in. The only difference was an HDD rather than an SSD. So I begin troubleshooting...

Swapped out RAM, HDD, Power Supply... Tested all of those components and they all passed... So I figured Mobo so I ordered a new one. Same problem... Finally decided it must be the processor... ordered a new one. Same problem. I took the mobo out of the case and put it on cardboard. I also unplugged the various leads from the case except for the power. Then I connected everything to a different case (same model though).

I taken out the cmos battery, unplugged every audio and USB cable from the case, booted without the keyboard plugged in. I have essentially built a completely new computer out of the same model components with the same issues. On the times I have been able to boot in, I have received BSODs of 0x3B, and 0x1E. I can run sfc /scannow in safe mode, but it is hit and miss in normal mode. If it misses, I get a BOSD. I am at a loss... what else can I do? Maybe buy completely different components and a different case. I need some insight badly. Please help me!! Thank you for your time! My components are below.

Thanks for the quick reply. So I have swapped out the ram completely with some other DDR3 with a slower speed. I also ran Memtest on the new RAM and after like 8 passes nothing was wrong. If I completely remove the RAM the mobo beeps at me but doesn't display any video (can't remember if that is typical or not, haha). So given the above testing do you think the POSTing issue could be the speed of the RAM? Let me know. Thanks!!!!
