Win7 64bit strange BSOD's ..

[Igoris Bo Modilinos]

Hi all. Sorry for my English.
I have serious strange problem.
I have two HP DC7800 workstations at home (win7-64bit, e8400, hd6570, 4gb, one 500gb hdd, other 630gb hdd).
So, these computers hard working every day (photoshop, premiere, outlook, etc.).
And..... 5 days ago i have had very bad surprise. In one hour i get 4 BSOD's from one machine!!!
Scenario:
received new email in outlook, answerred. BSOD.
restart automatically, loading windows, login- BSOD.
restart automatically, loading in safe mode- loading stops at classpnp.sys file.
turn computer off- turn computer on- loading normally, but at screen was only mouse cursor in black background.
turn off- turn on- finally loaded, everithing fine to the present. 5 days of work without any problems.
i have tested memory with Memtest for 10 passes. No errors.
i have tested CPU with stress test. No errors.
I have checked HDD for errors, everything is good, no errors in SMART too.

I have downloaded BlueScreenView application:

So.... Can this be software problem? Or it seems to be hardware?
Many thanks..

It seems that now your computer is working fine. Do you have all the updates(Windows)? What antivirus are you using? Did you check your computer for viruses? Are your graphics driver up to date?
1. Run chkdsk /f in command promt.
2. Run disk defragment.
3. Take out the ram sticks, reseat it properly.
See how it goes.......then reply.

Hi. My drivers, BIOS, windows updates always are newest. Computers do not have malware, viruses or rootkits, i have been tester with several antiviruses.

 

[lonewolf7]

So what's your status now, are you still getting BSOD's?

 

[Igoris Bo Modilinos]

no, no more BSOD's. Now i'm thinking, it was software or hardware problem..

 

[lonewolf7]

Don't worry it happens sometime. I think it was a conflict between your software which causes this.
