I built my PC last year and had problems with it which were fixed but now months later I'm getting random freezing. The computer freezes completely and is non-responsive, I have to do a fore restart.
I started off with using Anti-Virus and Malware scans. Nothing found.
I did a memory check with the Windows own RAM checker. No problems found.
Did a thorough hard drive check. No errors found.
All drivers and Windows Updates are up-to-date.
Motherboard: ASUS P8Z77-LX
Processor: Intel i5 3570K
RAM: Corsair CMZ8GX3M2A1600C9 Vengeance 8GB
Graphics Card: Asus Nvidia GeForce GTX 760
PSU: XFX 650W XXX Edition 80+ Bronze Semi-Modular Power Supply
Hard Drives: Seagate Barracuda 3.5 inch 2TB 7200 RPM 64MB 6GB/S Internal SATA Drive (Secondary)
Seagate ST1000DM003 Barracuda 1TB 3.5 inch Hard Drive (Primary)
I also have been monitoring temperatures and everything seems OK except with the ASUS Suite 2 which seems to be giving me warnings of the PSU volts being too low occassionally but CPUID HWMonitor says they are steady.
If you need more info, let me know.
