Hey everyone,
I'm not very experienced with PC hardware or any of that but I have been having many crashes while playing games. It's actually only really Fortnite, There is a few things I want to tell you guys before I get into it but I bought this PC off of a close friend of mine that went into the Navy. The specs on the computer are pretty good I would say but obviously there is something I am doing wrong. In the middle of games ill get a blue or black screen, sometimes green. My mouse might or might not be completely disabled but the time the crash client comes up. Sometimes it will give me the error "Application has been blocked from accessing graphics hardware."Another thing I ran into a few times is when I launch my fortnite it will just say "busy" on the tab then immediately switch back to launch. I had some guy come look at my computer and there was drive that wasnt being read and it ended up being completely dead. Maybe thats the reason this stuff is happening? idk.
Like I said, not really experienced in this so that's why I am here. I honestly feel my computer can just be running more smoothly as well since the specs are pretty okay. I'm just gonna list stuff thats probably important but thanks for reading. I'll play other games if I have to Fortnite client just hates me for some reason.
help plz

NVIDIA GeForce GTX 980 Ti
Samsung SSD 840 EVO 250GB
Intel i7-4770K 3.50 GHz

Please follow the steps below to help troubleshoot your system.

Step 1:
Download Speccy to your desktop
1. File > Publish Snapshot. This saves your snapshot to their servers
2. Copy and Paste the link to your next Reply

Step 2:
Click on Start menu
Type command to start searching
Right click on command prompt in list and select Run Administrator
and Paste each the commands below into the command prompt and press Enter key
1. sfc /scannow

2. (Windows 8 or higher)
dism /online /cleanup-image /restorehealth

If any Errors are found with sfc /scannow then:

Copy and Paste the following command, and press ENTER:
copy %windir%\Logs\CBS\CBS.log "%userprofile%\Desktop\CBS.txt"
This will copy CBS.txt to your desktop
Upload CBS.txt file
(if it is to large then compress to a .zip file and/or use file sharing site and provide the link)

Step 3:
Download Process Explorer to your desktop
  • Right Click on the procexp64.exe or procexp.exe and Select Run As Administrator
  • In the View menu click on Select Columns
  • Check Verified Signer, Virus Total on Process Image Tab
  • Select the Process I/O tab and check Reads, Rights and click OK
  • Select Options Menu and Check Verify ImageSignatures, > Check
  • Double Click on the CPU Column to sort by highest CPU usage.
  • (Highest CPU Processes should be at the top once sorted properly)
  • Wait approximately a minute
  • Select Save or Save As from the File menu
  • Save SystemIdleProcess.txt to Desktop
  • Upload file to your reply

Then run the following Hardware Diagnostics:

Step 1: Test Hard Drive
Download USB Seatools Boot file to your Desktop
1. Uncompress the .zip file
2. Open the USBbootSetup-SeaToolsBootable folder
3. Double click on the SeaToolsBootable_RC_2.1.2.usbBootMaker.exe file
4. Follow the steps to create a Bootable USB
1. Boot from the Seatools USB and Run the program
2. Once it starts it will scan for all drives connected to your computer.
3. Select drive you want to test.5. If it passes then
4. Select the Long Generic Test under the Basic Tests menu
5. When the test is complete you will see the result under Test Status
6. The test will indicate either Pass or Fail.
7. Provide the Results in your reply.

Step 2: Test Memory:
Run memtest86+ version 5.01 for at least 8 passes.
Memtest86+ - Advanced Memory Diagnostic Tool
This may take hours so plan to run it overnight.
Testing takes approximately 1 - 2 hours /GB RAM
Just 1 error is a fail and you can abort testing
Then test 1 RAM module at a time in the same DIMM each for 8 or more passes
When Memtest86+ has completed 8 or more passes take a picture and post an image and upload to your reply
MemTest86+ - Test RAM BSOD Tutorials

Step 3: Stress Test Your CPU - Prime 95
Download the correct version below:
Windows 64-bit:
- extract the contents of the zip file to a location of your choice
- double click on the executable file
- select "Just stress testing"
- select the "Blend" test. If you've already run MemTest overnight please run the "Small FFTs" test instead. (run all 3 if you find a problem and note how long it takes to error out with each)
- "Number of torture test threads to run" should equal the number of CPU's times 2 (if you're using hyperthreading).
The easiest way to figure this out is to go to Task Manager...Performance tab - and see the number of boxes under CPU Usage History
Then run the test for 6 to 24 hours - or until you get errors (whichever comes first).
Monitor the CPU temperature using either your motherboard monitoring software, SpeenFan or HWMonitor. DON'T let it exceed 85ºC. If it does, then you probably have a CPU cooling problem. This won't necessarily crash the system - but check the output in the test window for errors.
The Test selection box and the stress.txt file describes what components that the program stresses.
