I have purchased a new pc last week but I have been experiencing the weirdest crashes.
The PC was purchased from a quality vendor with all new parts. The specs are as follows:
-INTEL i5 4670k
- ASUS B85M-G
- ASUS 2GB DDR5 GTX770
- 500GB HARDDISK, 7200RPM, SATA6G
- 8GB DDR3 1600MHZ HYPER-X KINGSTON
- 550W XFX 80+ CERTIFIED PSU (SEASONIC)
On a unrelated matter: I realise that the 4670k is the overclock edition while the motherboard does not support overclocking.
I have installed Windows 7 ultimate and ran the windows update and installes the latest video card drivers and directx.
I noticed while playing FFXIV that when I alt+tab and browsed a bit, the PC would crash. The crash can be described as a full black (or other color!) screen and the keyborad/ mouse would not work anymore.
It went fine ingame, great FPS, low GPU temperatures (<50 C) but when I went alt+tab and browsed a bit, the PC would crash. Often even, the pc would not start for a few minutes
Following this I did the following:
I tested GPU stability by running Furmark.
The benchmark/stress test performed fine but AFTER the test, when pressing the 'compare scores online'..it would crash again.
Alarmed by this, I ran various tests..I tested HDD stability using WD diagnostic tools. I stress tested my CPU with prime95 and ran memtest86 to test my ram. No problems found.
One pattern however: AFTER putting my GPU on full load and doing stuff that was 'easy' such as browsing, instant crash.
Installing different browsers (maybe it was a browser issue?) did not help. Installing Windows 8.1, did not help.
I am at the end of my rope. I have no clue what it is, not even completely sure if its hardware/driver/software related.
My Windows (7 or 8.1) crashes AFTER stressing my GPU in Furmark (or a game). During stress, performs as expected, but afterwards, immediate and full windows crash
CPU tested using prime. Pass
HDD tested using WD Diagnostic tool. Pass
Memory tested using memtest86. Pass
Gpu tested using Furmark. During test: pass, afterwards FAIL.
