Hello entropical, let me see a few things if you don't mind. Would you please go into bios and give me the values of the +12V, +5V and +3.3V. Also, while in bios, please look in the Advanced tab, Sata configuration and tell me what the Sata configuration is. Also tell me if your BIOS Version is 2202..
Also, please , if you don't already have it, download and install CPUz
CPU-Z | Softwares | CPUID and post screenshots (
http://www.sevenforums.com/tutorials/9733-screenshots-files-upload-post-seven-forums.html) of the CPU tab, the Mainboard tab the Memory tab and the SPD tab. On the SPD tab, in the upper left you can select each Dimm Slot. Please just post screenshots of just the Dimm slots with ram in them.
While we are posting screenshots, Please click start, type Device manager, click on Device Manager and post a screenshot of it for me. Also please post a screenshot of Disk Management

Also, please open an elevated command prompt ( click start, type
cmd in the search box,
right click on the cmd entry and select run as administrator) in the black box that opens, copy/paste
sfc /scannow. If you decide to type it, notice the space between the sfc and the /. It is a system file checker which will scan your system files and attempt to correct any missing or corrupt files. What we want are the results to say windows found no integrity violations. If it says files were found but could not be repaired, close the box, reboot and run it again, after opening the administrative command prompt. You may have to reboot and run it three times for it to repair all system files. If it can't repair them after 3 reboots, let us know.
All of those screenshots may take 2 or 3 posts, which is fine with me. Hopefully we can find something. But, from what I can see, I would agree with Arc that it looks a lot like a ram problem.
