My computer keeps freezing

[Altethia]

Hi I am really getting frustrated with this as I have done literally everything to fix this problem but it wont work.Anyways what the issue is,my computer will freeze when I try to download games or play them(Browsing the internet seems fine but if I watch videos it will freeze in like 5-10 minutes as well as playing or downloading games),it will freeze on the image of what I was doing at the time it froze(no black or blue screens)and the mouse and keyboard will be unresponsive also when I have the volume up sometimes(not all the time) a buzzing noise will come out of it.I took my computer into the shop a couple days ago and when I took it in they said it was probably a hard disk issue, but after they tested everything they told me it was the power supply so I went out and got a new one but still no luck,so I even did a reinstall of windows 10 and that didn't work either, and also I got a new graphics card even before taking it into the shop so honestly I have no idea what the issue is. I'm honestly at a loss and this is just frustrating me but here are my specs(taken from speccy)

Operating System: Windows 10 Home 64-bit

CPU:AMD FX-4300 Vishera 32nm Technology

RAM: 8.00GB Single-Channel DDR3 @ 669MHz (9-9-9-24)

Motherboard: ASUSTeK Computer INC. M5A78L-M LX3 (AM3R2)

Graphics: K242HQL (1920x1080@60Hz) 2047MB NVIDIA GeForce GTX 950 (ZOTAC International)

Storage: 931GB Western Digital WDC WD10EZEX-00KUWA0 ATA Device (SATA)

Optical Drives:HL-DT-ST DVDRAM GH24NS95 ATA Device

Audio: High Definition Audio Device

Also the power supply I got was an EVGA 750 BQ 750 watt Bronze power supply

also the temps on my computer range from:

cpu:7°C-17°C

motherboard:31°C

Graphics Card:33 °C

Hard disc drive: 25 °C

That's how it is right now when not playing games,but I cant download or play any games due to constant freezing.Also I don't think the computer is overheating since its always really cool when playing games.

Your temps are very moderate if you measured while in a demanding game. Uncertain about PSU diagnosis since the more than adequate replacement PSU did not resolve the problem. Likewise the GPU which you apparently replaced as well.

In troubleshooting the best idea is to try the diagnostic steps which are least cost first. The second principle is to replace components with 'known good' alternatives (if problem goes away when you replace something, it is a good bet [not always] that you found the problem).

Of course there is a zero-eth principle which come before the others - run several Anti-malware tests - like Malwarebytes Anti-malware (free version) and BitDefender Rescue CD (free). Any indication of problems (even if 'removed') should lead to a visit with Broni ( https://www.techspot.com/community/forums/virus-and-malware-removal.28/ )

Least cost diagnostics include:
- check for error codes in Event Viewer and turn off 'automatic restart on error'
- checking temperature and voltage ranges leading up to an error condition (watch video for only 2-3 minutes)
- checking SMART on HDD
- running memtest86 from Passmark overnight

I am suspicious about malware in your case, so test thoroughly.

It wouldn't be malware because we've re-installed the entire OS using a fresh copy of Windows 10.

OK, I'll accept that if you are certain of your installation media.

So, on to the next:
- check for error codes in Event Viewer and turn off 'automatic restart on error'
- checking temperature and voltage ranges leading up to an error condition (watch video for only 2-3 minutes)
- checking SMART on HDD
- running memtest86 from Passmark overnight

I have used SPeccy and HWInfo to check temps/volts

Try to remove the graphics card, and use an air duster on fans heatsink.

Did you motice a buzzing with the volume up before the freezing issues? If not it may be indicative of a grounding issue.. Try changing the kettle lead... It's a stretch but has happened before.
