Windows 7: Multiple BSOD errors

Multiple BSOD errors

Dear Staff,

Recently encountered various BSOD errors, can't determine any pattern in them as they happen during all kinds of activities. Laptop is 2 years old and is an xps l502x, this all started happing in the past week, had no errors before that. Clean installed windows but errors persisted and looking at similar BSOD error threads on this site hasn't lead to me solving it.

The main errors im getting are something like;


"COOOO135 %hs is missing"

"Stop: 0x000007E"
"Stop: 0x00000F4"

Dump files are attached, i'll be running memtest tomorrow as i have the day off. Thanks in advance for any advice or info.

Welcome to SF jripper, please follow the Blue Screen of Death (BSOD) Posting Instructions :) .

At the moment it appears to be an issue with the storage system.
warning   Warning
The Following Method Should NOT Be Performed On An SSD!

Testing the HDD:
  1. Perform a Disk Check | Disk Check- Scroll down to OPTION TWO of the tutorial and use the /R switch in the CHKDSK command | chkdsk C: /R.
  2. Then Post the Disk Check results following | This Tutorial.
  3. Once back in Windows, download Crystal Disk Info and post a screenshot (multiple shots if you have more than one drive).
  4. Download SeaTools for DOS if you don't want to use a CD to test the HDD you can use YUMI Multiboot USB Creator to create a bootable USB (instructions are found at the bottom of both pages).
  5. If SeaTools for DOS is unable to recognize your HDD:
  6. Visit HDDdiag and follow the instructions | Or follow the instructions below.
If SeaTools For DOS does not recognize the drive;
Boot into the BIOS using the *Fx key.
Look for an entry called SATA Mode (or something similar), it should be set to IDE / AHCI.
It's probably set to AHCI which is why SeaTools doesn't recognize them in the DOS environment.
Set it to IDE then save and exit usually by pressing the F10 key.
Now boot into SeaTools and it should detect the drives.
Start the Long Test and let it run.
Upon completion don't try to boot into Windows as it will only result in a BSOD, go back into the BIOS
and change the SATA setting back to what it was in the first place.

Hi again,

Ran seatools long test this morning. I can't seem to find the log, it's not in programme files/seagate and i didn't save it, but it said "passed" for both the long test and the short test which it ran automatically after the long. Is that info any use or will i have to run it again?
