Random BSOD, multiple codes - ntoskrnl.exe, fltmgr.sys, Ntfs.sys
Hello,
A couple weeks ago i bought a brand new notebook (a Lenovo G470, running Windows 7 Home Premium x64 ) and a few days ago, it started BSOD'ing, to the point that it was impossible to use the computer because the BSOD happened almost every time.
The BSOD all had random error codes and almost always were because of ntoskrnl.exe, one time fltmgr.sys and another time fileinfo.sys (i think), according to bluescreenview.
I ran memtest for 2 passes and it right on the beginning it found like 400.000 errors.
I called Lenovo support and they told me to format the computer using Lenovo's system partiton. After the format, i just left the pc running idle and, after a while, it BSOD again.
Booting in safe mode did not give BSOD. I also ran Ubuntu 10.04 via Live USB and did not have any crashes. In Ubuntu, i left the computer running multiple 1080p mkv movies in loop for half a day and also opened dozens of programs at once to try and stress the system, and no crashes. Temperature was normal.
After that, i ran:
Memtest - No errors (the 400k errors found before dont appear anymore)
Prime95 for a few hours - No errors/crashes
Furmark - No errors/crashes, temperatures ok
Seatools (Seagate HD Diagnostics) - No errors/crashes
Lenovo's LSC Lite HD and Memory diagnostics - No errors/crashes
Even with all those tests, i still got a few BSOD later.
So, i was thinking that maybe the Lenovo's recovery system had a corrupted windows installation (or there was a conflict with the pre-installed softwares/drivers) and decided to try another windows version. I formatted again/deleted the partitions and installed Windows 7 Ultimate x64.
After the second format (now with Windows 7 Ultimate x64), i left the pc running completely clean of drivers and applications for a few hours and no crashes. So, i installed a few drivers and a few applications. I went to sleep and left Windows downloading updates. All seemed well. But this morning, when installing the Windows' updates, the system BSOD again. (The dump file is attached)
I really want to make sure that i have a hardware problem before sending it to the repair shop, which can take up to 30 days to get the computer back.
So, any help will be greatly appreciated! And sorry for the really long text,i wanted to give the max number of informations as possible.
The system specs are:
Model: Lenovo G470
Processor: Intel Core I5 2410m
Ram Memory: 4 GB, 1 stick
Graphics: Intel HD 3000
OS: Windows 7 Home Premium x64 OEM
(After 2nd format, Windows 7 Ultimate x64 retail, installed yesterday)
