Blue Screens, CPU spiking, and general problems. Help?

May 4, 2015 at 14:28:52
Specs: Windows 7
Where do I start? About a month ago my GPU began artifacting. CPU would spike to 100% and computer would blue screen. Temps were a little high but nothing ridiculous so I cleaned out all the dust, replaced the graphics card and I decided to reformat as well. I reapplied the thermal paste to my CPU while I was in there and I had no other issues for almost a month. I thought my problem had been solved.

Now, my computer has blue screened 3 times in the last few days again. CPU spiking, but staying between 80%-100% with next to NOTHING running. Froze/Blue screened on me last night so I manually restarted. While starting up it just simply failed to start and windows suggested I restore to an earlier point. I did. And here I am. I'm almost positive this is a hardware related issue. Because even after reformatting I'm having the same issues. I use my computer mainly for browsing and gaming. (CS:GO, LoL, and various other steam or indie games. Nothing super tolling besides CS:GO)

MOBO: Fatal1ty
GPU: Geforce GTX 960
CPU: Intel Core i5-2400 3.10GHz
Memory: 8.00 GB RAM (7.98 GB usable)
Windows: 7 64

If I left out any info, just ask. I really appreciate any help.

If the computer is spiking like that then something must be hogging it. Try this and see if you can see what it is:

I would also run these free and safe malware checks just to get an idea whether you've picked up anything:

(blue Download button near top - not anything else on the page).
Download and "Save" the file somewhere. Go to the saved file then double click it to run the program. Use the "Scan" button, followed by the "Cleaning" button.

Junkware Removal Tool (JRT)
(blue Download button near top - not anything else on the page).
Download and "Save" the file somewhere. Go to the saved file then double click it to run JRT. It might appear to have stopped at times or flash the screen but sit tight until it has finished.

(green Download button top right - not anything else on the page)
Install and Run the program but before doing its Scan go to "Settings > Detection and Protection" and put a checkmark in "Scan for rootkits". Quarantine anything it finds.

If any of the find anything please copy/paste the logs on here and let us know if there has been any sign of improvement. If there's malware further cleaning is likely to be necessary.

Always pop back and let us know the outcome - thanks

Where are you reading the CPU usage? Check in Task Manager> Processes to see what is using the cycles.

How are you monitoring the temperatures? What are the real time temps and voltages?

How did you clean out the dust? Best to use canned or compressed air. Don't forget to blow out the power supply from both ends. DO NOT ever use a vacuum cleaner. Static discharge can damage sensitive components.

If you just formatted when you reinstalled you may have left behind something from a rootkit. The best way to prevent this would be to delete ALL partitions, create a new partition and then format. After which the reinstall would be completely clean.
Second, If you saved your personal files and then put them back, you should first scan them with antivirus program, Malwarebytes, and possibly other things as well.
Scan system as recommended above and copy/post the logs back for review.

You have to be a little bit crazy to keep you from going insane.

I've run a few scans. I do have Malwarebytes already, so I'll be running that as well. I have also been just going through and uninstalling any program that I no longer need. I got rid of my old virus software (Panda Antivirus) as it looked very tolling on my CPU (Thanks to Process Explorer that you suggested, thanks!) and went back to Baidu (much lighter, cleaner, etc). Baidu has already found a few worms and suspicious files that Panda never detected. Will update after scans and restart.

@ OtheHill I was reading CPU usage through Task manager, but now through Process Explorer (thanks to Derek).

I used canned air. I built my computer myself so I know a bit about hardware and how to take care of it.
