I had 19 crashes in the past 4 month. A computer is 13 month old, the first BSODs happened on 27/12/2011. The exact statistics:
0x1A MEMORY_MANAGEMENT - happened 10 times (the 5 most recent crashes were 0x1A)
0x24 NTFS_FILE_SYSTEM - 4 times (the most recent happened 3 weeks ago)
0xE4 WORKER_INVALID - 3 times (the most recent happened a month ago)
0x19 BAD_POOL_HEADER - 1 time (2 weeks ago)
0x9F DRIVER_POWER_STATE_FAILURE - 1 time (3 month ago)
Besides BSODs, I'm also seeing event 11 in the event log, with messages like "The driver
detected a controller error on \Device\Harddisk3\DR3". Harddisk3 is likely to be a WD Passport drive plugged into USB 3.0 port. The drive is used for Acronis backup. Interestingly, the event 11 started to happen on 19/12/2011 (shortly before the first BSOD).
1) I'm ruling out RAM issues. Few weeks ago I bought a brand new 4x4GB kit and replace the old RAM modules. The problem still continued.
2) I upgraded motherboard's BIOS, downloaded and installed all the recent drives from ASUS site, installed the latest AMD Radeon drivers
. All with little help.
3) chkdsk on all drives didn't report any errors.
4) I used Kaspersky Anti-Virus 2011 before, and upgraded to Kaspersky Anti-Virus 2012 in March. This upgrade had little effect on BSODs.
5) I'm also using Acronis True Image Home 2011.
6) System configuration:
CPU: Intel i7-2600 (stock clock)
Mainboard: Asus P8P67 LE
RAM: Corsair 4x4GB kit CML16GX3M4A1600C9B at XMP speed (G.Skill F3-12800CL9D-8GBXL before that)
GPU: Fanless Gigabyte Radeon HD 5750
SSD: G.Skill Phoenix PRO 120GB as OS drive
SSD: Intel 520 120GB SSD as data drive (this was added recently - BSOD happened before this SSD was installed)
Discrete NIC: Intel Gigabit CT Desktop
Discrete COM port: MANHATTAN Serial PCI Express Card
PSU: Seasonic X-650
UPS: APC Smart-UPS 750 VA (SMT750I)
OS: Windows 7 64-bit SP1
Interestingly BSODs often happen at night, when the load is minimal. So I don't think it happens due to overheating.
Any help would be appreciated.
