Randomly BSOD while using or idle, 0x0a,0x50,0x3b,0xd1

Welcome aboard.

I am assuming that there is some virus. First make it sure that the system is free from viruses. Scan the system for possible virus infection.

• Anti-rootkit utility TDSSKiller
• Windows Defender Offline

Let us know the results.

EDIT : Uninstall McAfee Using McAfee Removal Tool. It cannot give you the protection that you need, and it is a very well known BSOD causer.
Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Download and install those, and then run full system scans with both of them, one by one.

Next step, do some disc checks.

1. Update your SSD's Firmware (Skip it, if it is not a SSD)
2. Re-seat the sata and power.
3. Run chkdsk /f/r, following the option two of the tutorial Disk Check
4. Seatool for dos: SeaTools | Seagate download
   Burn it in a blank cd. boot from the CD, click on "Accept", wait for it to finish detecting the drives, then in the upper left corner select "Basic Tests", then select "Long Test" and let it run.

Post a screenshot of your HDD using it.

Apparently the HDD is in a good condition. It looks OK, other than the sign up time.

In the last incidence, there are two failures I am finding. The first thing is the display driver.

Code:

fffff880`09624f78  fffff880`0487238eUnable to load image atikmdag.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for atikmdag.sys
*** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys
 atikmdag+0x5538e

And again ...

Code:

fffff880`09624f08  fffff880`04004a35Unable to load image atikmpag.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for atikmpag.sys
*** ERROR: Module load completed but symbols could not be loaded for atikmpag.sys
 atikmpag+0x4a35

Coz the display driver is very old.

Code:

lmvm atikmpag
start             end                 module name
fffff880`04000000 fffff880`0404a000   atikmpag T (no symbols)

Update it, from Latest AMD Catalyst Video Driver for Windows 7

The other thing is network related, though not very specific.

Code:

And it is also very old.

Code:

update the network driver.
First, download the network card driver from manufactuer's website. Downloads | Broadcom
Then reinstall the driver:

1. Click the Start Button, type "devmgmt.msc" (without quotation marks) in the Start Menu Search box and press Enter.
2. Double click to expand "Network adaptors".
3. Right click your network card and click Uninstall.
4. Check "Delete driver software for this device" check box, click OK.
5. Restart the computer
6. If windows does not auto configure the appropriate drivers at startup, install the downloaded one manually.

Let us know the results.
