So my PC randomly freezes, no BSOD at all, just freezes what im doing on the screen, sometimes the audio freaks out and beeps or buzzes, requires a hard restart, sometimes happens after 5minutes of use or sometimes does not happen at all for a whole day.

System specs are:

Windows 7 Ultimate (x64) Service Pack 1 (build 7601) 3.50 gigahertz AMD Phenom II X4 970 GA-880GM-UD2H motherboard 8190 Megabytes RAM

Samsung SSD 840 PRO Series [Hard drive] (128.04 GB) WDC WD10EZEX-22BN5A0 [Hard drive] (1000.20 GB) WDC WD5000AAKS-00UU3A0 [Hard drive] (500.11 GB)

AMD Radeon R9 290 XFX 700W PSU

Went to event viewer noticed quite a few erorrs mainly this one.

"Unexpected failure. Error code: D@01010004"

Also i'veuploaded the event log with only errors Here

Lastly ive ran a memory diagnostic with no errors, all 3 hard drives are new and replaced any old ones, once the random freezes started.

Any help would be very very much appreciated.
