Hello. First of all sorry to bother you all with another BSOD topic, but this is bugging me since April this year. I bought a new pc with the following specs earlier this year. Intel core i5 2500 3.3ghz Asus P8H67-v 4gb (2x2) DDR3 1300 OCZ Gold Sapphire Radeon HD5770 1gb DDR5 OCZ 600w SxS2 And 2 HDs, one 320GB, bought a couple years ago, and a brand new 1TB one. Windows 7 OS. Everything was working perfectly for a few weeks, but then it started BSODing everytime, with no pattern at all, back then i was sure it was a hardware issue so didn't bother saving logs or such. Many many many months and tests later, to no result, i found out that my Motherboard lacked the B3 revision, that was music to my ears to know, cause it would end all the BSOD just by changing the mobo to a revised one. Instead of changing to the B3 revised mobo, the store i bought let me trade my model for another one in stock, because till they send to asus and back would take a long time. I picked up an ECS H67H2-M Black Series. B3 revised. I was finally having a fully functional PC, but then, 2 days later the first BSOD happened. EVERY startup, it has a 100% chance of BSODing, sometimes just after windows boot, sometimes after a couple mins. The weirdest thing is, if i boot the PC, then turn it off before windows boot, and then boot again, BSOD won't happen, i have no clue why this is happening, my best guess is a HD failure or maybe the PSU. Here's the log after every BSOD: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 1046 Additional information about the problem: BCCode: 19 BCP1: 0000000000000003 BCP2: FFFFF8A00422FA60 BCP3: FFFFF8A00422FAE0 BCP4: FFFFF8A00422FA60 OS Version: 6_1_7600 Service Pack: 0_0 Product: 256_1 and the 6 last minidumps below. Sorry for the wall of text and the annoyance, googling for solutions i stumbled in this forum and got impressed by the community help here, so i'm giving a shot. Thank you in advance.
