Okay, so prepare for an absolute wall of text..
- Corsair CX 750M (upgraded from previous Corsair CX 500W)
- Intel LGA1150 Core I7 - 4770S
- MSI GeFroce GTX770 2GB Gaming PCI-E
- MSI LGA150 b85M-E45
- Crucial DDR3 BasllistiX 1600Mhz 16GB KIT
- Samsung DVD + RW SH - 224DBfBEBE SATA BULK
- Seagate Barcuda 2TB SATA3.0
- *added* Windows 7
Some may be spelled wrong, read off an old scrap of paper.
Over 3 months ago, without no new hardware or obvious software, my computer began having freezes and crashes. They started becoming more of a problem than a nuisance after a week or so, when they would occur from everything within 5 minutes, to ~3 hours.
There are several different types of crashes which occur:
- Regular crashes - instantaneously and with no warning (hard reset needed)
- Sounds & music slowing down, beginning to fall behind and suddenly getting stuck and sounding awful to the ear, when the screen goes blank - hard reset needed
- Nvidia share or display driver crashes as a forewarning - hard reset needed
- Not entirely a freeze, but everything on screen freezes while programs keep running, as well as sounds and music. - hard reset needed
That's about it, I believe.
And a problem on startup which I've encountered:
- Black screen upon start, some sort of error code with either "A2" or "9c" - sometimes unplugging my keyboard makes it boot, other times a hard reset would be required
All of the crash logs points in the direction of something with either my motherboard or my graphics card. But now comes the fun part.
I have sent in my graphics card to begin with. No errors found with it being tested in a different machine.
My computer can run without crashes for a whole day, and even more if I bothered (no crashes occur just to be clear), with no graphics card in.
I then proceeded to send in my entire PC, but again. Nothing was found, even after testing in various stress programs and games for days.
My PC may crash after 5 minutes in a GPU stress test, or run for at least one and a half hour.
I then upgraded my PSU just to be sure it actually got the correct power supply. But please note, that this PC is 3 years old. So there should not be any sudden problems with the PSU which has worked for 3 years (almost). I had an electrician check all power sockets, and they had no problems. I replaced all extension cords, and tried running my PC only off a separate one from all my other stuff (like my display and speakers). Nothing changed.
I tried getting help on another forum, and I thought my issue was fixed as it didn't crash for a couple of days and abandoned the thread.
I'm currently communicating with some guy from the support of the website I bought my PC from via e-mail, who is absolutely clueless about what is up with my PC. So I turned to you guys!
I have attached some Logs etc.zip 180.06KB 1 downloads. you may find useful.
Fixes I've tried so far:
- Clean install drivers
- Update BIOS
- Install new & older drivers
- Clean installing Windows
- Running without my GPU (fixes problem)
- Running with my brother's GTX1070 (fixes problem)
- Doing memtests and CPU stress tests
- Replugging all PCI-E cables in my PC.
- Cleaning my computer (which was already cleaned just a month ago)
Throwing it out of the window in frustration
I can obviously not keep using my brother's GPU, nor am I able to use the computer sufficiently enough for both gaming and regular things like watching Youtube without a GPU.
So as you can tell by now, this is not just some common turn it off and on again problem. It HAS to be hardware-related (looking at you GPU and motherboard). I still have my warranty until the 27'th of may, but time is running short, and I cannot afford to buy new parts!
Thank you in advance!
