Windows 7: Bsod ntoskrnl+748c0

Bsod ntoskrnl+748c0

My first post! I keep getting BSODs with various error codes. I downloaded and used Blue Screen View. It seems all (with 1 exception) of the .dmp files have the the crash address of NTOSKRNL.exe+748C0. I keep researching and they results say there's a bad driver in the system. I ran Verifier and it found a problem with Avast Anti-virus. I deleted it and all register entries for Avast; I'm now using Bitdefender. Ran Verifier on it and there were no problems.

Help!
Thanks!

There are various different BSODs including stop 0x51. So there is a chance of an infection there. Do two things.

Scan the system for possible virus infection with the following programs.
Stress test the Graphics Card using Furmark.
Video Card - Stress Test with Furmark
Take a screenshot of the furmark window before closing it. Upload the screenshot for us. Also let us know if you have experienced any crash/BSOD and/or artifacts during the test.

Let us know the result. A camera snap of the memtest86+ window before closing the program will be nice.

Also upload your MSINFO32.nfo file.
  1. Click on the start button
  2. Type "msinfo32" (without quotes) in the search bar of the start menu, click the resulting link. It will open the System Information window.
  3. File>Save. In the "File Name" filed, put "MSINFO32" (without Quote), give the save location to desktop, and click the "save" button.
  4. Give the time for processing, it will save a .nfo file on your desktop.
  5. Zip it, and upload it following the instruction.

Update

I've run the tests that you've suggested.

I ran:
- TDSSKiller twice - both no issues
- Memtestx86 overnight - no issues
- Window Defender Offline - no issues
- FurMark - no issues
- Kaspersky Security Scan - no issues

I've attached pix.

The computer would not start last night. It'd go through the BIOS start and then all I had was a blank screen and a blinking tab. Reverted to my Repair Disk. Checked the Start files and it did a repair.

All seems well now, as I've rebooted a few times.

Any ideas?

Many thanks,
Mark

Remove the Crucial RAM that is there is slot 0. Using RAMs from different brands is not a good idea.

Also run MemTest86+. You ran MemTest86. You must run MemTest86+.

Actually, I ran memtest95+. It ran overnight, but found nothing.

Here's something weird: I downloaded the latest mb BIOS. Tried to install 2x, and both times I got the attached bsod.

I've downloaded several drivers and deleted others:
VIA Tech - usb3 card - deleted
REALTEK - nic - downloaded and loaded Cupid HW Monitor - deleted, new version loaded

ARGH!

This is not the RAM failing, it's the DIMM slots failing. Replace your motherboard.
