Windows 7 BSOD 0x7A after every 1-2 hour

Question

My computer is BSOD'ing after every 1-2 hour. It is doing BSOD randomly. When I check for solutions no solution came up. Even the xml file is not readable.

• I'll try to take an screenshot of the BSOD screen and post here. Is there a way to read that Dump file?

• I am using a laptop so I can't check the power, cables etc.

Stop 0x7A, BCP2 0xC0000185 means you may have a hard disk problem—the system was unable to communicate with the disk. Make sure all cables are properly seated. If that doesn't solve the problem, examine the hard disk's SMART information using a program such as CrystalDiskInfo. The SMART status may indicate that you need to replace the hard disk.

The non-readability of the XML file only reinforces the possibility of a disk issue—the system may not have been able to write the file to disk.

---

All of the BSODs you've listed have 0xC0000185 for parameter 2. See if you can open up the laptop and check if the hard drive is firmly attached, and reseat it if possible. You should also post SMART information and run self-tests on the drive to see if there are any issues. Try running a disk check (CHKDSK) with surface scan to determine if there are any bad sectors.

Answer 2

I will appreciate if you could provide me detailed information about your computer specifications. Anyways, based on your query the following solutions will be definitely helpful for you:

Check problems with your hard disk, i.e. disk read/ write issues that prevent retrieving/ accessing data in the system files.

1. Double click Computer icon.
2. Right click a partition.
3. Select Properties.
4. Click Tools -> Check Now.

Another thing, check for memory issues as below:

1. Click Start, type "memory" in the Search Box.
2. Open the "Windows Memory Diagnostic".
3. Click "Restart now and check for problems".

Adjust the Paging File Size again. Set the most appropriate Paging File size as shown below. Then run ActiveX/ DLL registration scan with the help of Reginout software. Resolve any internal conflicts found.

1. Right click the Computer icon on your desktop.
2. Select Properties from the context menu.
3. Click “Advanced system settings” link.
4. System Properties dialog will be displayed.
5. Click Settings (Performance) -> Advanced.
6. Click Change (Virtual Memory).
7. Uncheck the box named “Automatically manage the paging file size for all drives”.
8. Select the system drive, usually drive C:\
9. Select “Custom size” option.
10. Increase the current paging file size, and then click Set button.
11. Click OK | OK | OK.
12. Restart your computer for the changes to take effects.

Without the actual crash logs (called DMP files) it is just a guess. This wiki will show you how to find and upload the DMP files for analysis
