bsod errors seemingly at random , once on skype and once on youtube

Hello i have been having a few problems with seeming random blue screens , i have recently placed my old hard-drive into this laptop as the one in this laptop seemed to have a problem with it and my old laptop had a broken fan. i replaced several drivers in order to make everything run on this laptop such as lan and wifi drivers. Im really not sure whats causing this so any help would be appreciated , thanks for your time

Welcome to the forum LucMelt95,

Perform a Clean boot:

• Troubleshoot Application Conflicts by Performing a Clean Startup

Reduce items at start-up. No software except anti-virus is required plus doing this improves the time for logging into windows:

Uninstall AVIRA and use MSE in its place. Microsoft Security Essentials is recommended from a strict BSOD perspective, compatibility & stability compared to other internet security software. Malwarebytes is a great combo to MSE. They are free and lightweight.

Also uninstall your existing Antivirus software before you install MSE.

Good and Free system security combination.

Other Tests:

 

• Upload a screenshot of your hard disk using Crystal Disk Info.
• Make a hard drive test from the hard drive manufacturers website.
• Test your Hard Drive with SeaTools.

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

• RAM - Test with Memtest86+

The goal is to test all the RAM sticks and all the motherboard slots.

Check your motherboard manual to ensure the RAM sticks are in the recommended motherboard slots. Some motherboards have very specific slots required for the number of RAM sticks installed.

If you get errors, stop the test and continue with the next step.

1. Remove all but one stick of RAM from your computer (this will be RAM stick #1), and run Memtest86 again, for 7 passes.

*Be sure to note the RAM stick, use a piece of tape with a number, and note the motherboard slot.

If this stick passes the test then go to step #3.

2. If RAM stick #1 has errors, repeat the test with RAM stick #2 in the same motherboard slot.

*If RAM stick #2 passes, this indicates that RAM stick #1 may be bad. If you want to be absolutely sure, re-test RAM stick #1 in another known good slot.

*If RAM stick #2 has errors, this indicates another possible bad RAM stick, a possible motherboard slot failure or inadequate settings.

3. Test the next stick of RAM (stick #2) in the next motherboard slot.

*If this RAM stick has errors repeat step #2 using a known good stick if possible, or another stick.

*If this RAM stick has no errors and both sticks failed in slot#1, test RAM stick #1 in this slot.

4. If you find a stick that passes the test, test it in all the other motherboard slots.

If Part 2 testing shows errors, and all tests in Part 3 show errors, you will need to test the RAM sticks in another computer and/or test other RAM in your computer to identify the problem.

In this way, you can identify whether it is a bad stick of RAM, a bad motherboard, or incompatibility between the sticks.

   Information

Errors are sometimes found after 8 passes.

   Tip

Memtest should be done overnight.
