Faulty Z77X-UD5H?
Hello,
Two weeks ago I built a new PC with a Z77X-UD5H and I'm having massive issues with it since last weekend. At the beginning I had random screen freezes while running Win7 (no CTDs or BSODs), I updated all mobo drivers and BIOS to F8. Everything went fine for a while but eventually I started getting lots of BSODs in Win7 even after recovery in safe mode. Decided to perform a clean install but now I'm locked up in W7 installation process: I boot from install DVD, loads stuff up, Win7 logo and then either a black screen (rare) or one of the following BSODs:
STOP: c0000139 {Entry Point Not Found} / PAGE_FAULT_IN_NONPAGED_AREA (STOP: 0x00000050) / STOP: c0000006 / STOP: 0x000000F4
I stripped the PC down removing the discrete GPU, connecting only either the SSD or HDD, tried BIOSes F7 and F4, checked PSU voltages with a multimeter and BIOS (those are OK) and connecting only a memory stick at a time in different slots with same faulty behaviour. I also performed a Memtest86+ with all my 4 sticks (3 passes OK) and with a single stick (7 passes OK).
The POST messages in the mobo when the BSOD triggers are either "0x0A" (IDE initialization starts) or "0x05" (which doesn't appear in the user's manual
???)
Everything points out to a faulty mobo; however, since I'm no expert any suggestion/comment will be really appreciated. Thanks in advance.
