This is my main desktop system:
Intel I-5 Quad Core 4670, Gigabyte Motherboard Z87M-D38, 128 GB Crucial SSD drive, WD Raptor Sata III 300 GBb Hard Drive, 500 GB WD 7200 Rpm Sata III 32 meg hard drive, 8 Gb 1600 Ddr3 A-Data ram, EVGA GTX 280 video card, Pioneer DVD-RW 24X, Seasonic 750 watt Psu and Windows 7 Pro and its about 2 years old.
Lately I have been having a few issues with occasional BSOD and in my experience, 98% of those are caused by ram or hard drive and that is where I believe my system is the weakest. A-Data Ram is not great and as much as I love Crucial Ram, Crucial ssd drives don't have a great service record. I have Corsair Vengeance 16GB (2x8GB) DDR3 2133 MHz (PC3 17000) Desktop Memory (CMZ16GX3M2A2133C10) coming and I bought one of the 240 Gb PNY Ssd drives listed in Deals here in that forum. I also have occasional mishaps coming up from sleep (PM) which I believe are related to the Ssd drive also and an occasional freeze up. Memtest86 shows nothing, I have run chkdsk /r with little or no results. I should add I have 2 2 gb external usb 3.0 drives plugged to the system but they are only on when in use and a Pioneer external Dvd-rw as well as a networked Brother Laser black HL 2040 and Lexmark Color Laser C544XL printer.
I am not crazy about Corsair ram, however I like to use only memory tested for the motherboard as I have found that cuts out a lot of issues and that Corsair model was the only ram I could find at a reasonable price...Amazon beat Newegg by $15 which surprised me. I will let you know how I make out.
