BSOD Every 30mins to Hour Caused by ntoskrnl.exe?

The particular BSOD you are having is a 0xF4 which is commonly caused by a failing hard drive:

Code:

things to try:

Fun the system file checker:

SFC.EXE /SCANNOW
Go to Start and type in "cmd.exe" (without the quotes)
At the top of the search box, right click on the cmd.exe and select "Run as adminstrator"
In the black window that opens, type "SFC.EXE /SCANNOW" (without the quotes) and press Enter.
IF when the program finishes running it says anything other than "no integrity violations found" run the command two more times
If after the third run of the command there are still problems run the SFC command at boot

Also run the check disk command from an administrative command prompt:

Code:

chkdsk /f /r

and last try running some hard drive diagnostics:

Hard Drive Diagnostic Procedure

:) Is the firmware for your SSD up-to-date?

Check for one and see if the stability returns.
