Hi,
About half a year ago I decided to build my own PC.
For this I used these components:
-Intel i5-3570K
-Club3D HD 6950 coolstream
-MSI Z77A-G45
-ADATA S510 60gb SSD
-some HDD I scavenged from my old PC
-2 x Kingston HyperX Blu 4 GB DDR3-RAM 1600
-Corsair CX600M PSU
Everything went good in the process and I ran it for a few months without any problems whatsoever. However, more recently I started to have a lot of issues, about every program I run (mostly games) crash 10~20 minutes in, they either CTD or I get the "program.exe has stopped working" window. I also had a few BSODs mostly in the more intense parts of games. At first I suspected my pirated version of windows 7 to be the problem, but after downgrading to a legit version of windows 8 I'm still having these issues. Therefore I assume the hardware to be the problem.
I tried running memtest86 for a day but I didn't get any errors, so I assume my RAM isn't the problem.
My CPU idles at ~40 °C and my GPU at ~50 °C. I don't know what else could be the problem. Please help.
Best regards, Spermcube.
