Hello everyone;
I have an issue.Couple days ago i bought a new [ G.Skill Ripjaws 4GB 1600MHz DDR3 Ram (F3-12800CL9S-4GBRL) ]
New ram was the same as the old,so i thought it wont get me trouble.After 3 days of no-issue work,i got BSOD.(Critical process died & In page error)Then i updated the BIOS.I unplugged and plugged the rams to 1. and 3.slots,but when i restart i got the screen of EFI Shell Version 2.31 [4.653].Then i reset the bios by waiting for 15 minute to plug it back.Finally computer opened with no issue,after 3 minute it froze and BSOD 'd again.Last thing i check before creating this topic,i realized BIOS doesn't see my HDD...
