BSoD - BAD_POOL_HEADER

Hello,

Since the problem existed after a clean install, I would suspect this is a hardware problem. We might as well eliminate the possibility of software first though.

Remove Norton with this tool: ftp://ftp.symantec.com/public/englis...moval_Tool.exe

Replace it with MSE: http://www.microsoft.com/security_essentials

Code:

SRTSPX64.SYS      Mon Jun 22 22:47:54 2009 (4A40425A)
SYMEFA64.SYS      Tue Jun 23 17:52:39 2009 (4A414EA7)
SYMEVENT64x86.SYS Wed Jun 24 16:19:12 2009 (4A428A40)
SYMFW.SYS         Mon Jul 06 20:29:22 2009 (4A5296E2)
SymIMv.sys        Mon Jun 22 19:11:56 2009 (4A400FBC)
SYMNDISV.SYS      Mon Jul 06 20:33:26 2009 (4A5297D6)

Also update Acronis TrueImage, as the version you are using has been known to cause some BSODs.

Install these Lenovo Conextant audio drivers: Lenovo Support - Conexant Audio Software for Windows 7 (32-bit, 64-bit), Vista (32-bit, 64-bit), XP (32-bit, 64-bit) - ThinkPad T410, T410i, T410s, T410si, T510, T510i, W510, W701, W701ds, X201, X201i, X201s, X201 Tablet

One dump blames them.

Code:

CHDRT64.sys       Wed Jul 22 17:57:53 2009 (4A678B61)

I would also suggest some hardware tests. Start with RAM: RAM - Test with Memtest86+

Also run a hard drive test, with Hitachi DFT. Download this ISO: http://www.hitachigst.com/hdd/suppor...2_v415_b01.iso

Burn it to a CD, following the directions in this tutorial: Burn Disc Image - ISO or IMG file
