Video Card - MSI R7850 Twin Frozr (ATI Radeon HD7850) What could possibly cause at the same time both a dead video card and 2 dead DIMM slots? Note also that DIMM4 was not even occupied at the time. After experimenting in multiple systems, I discovered my video card had died as it completely prevents POST in any system I try it in. After which my computer would not POST upon restart. Whenever either of those slots are occupied my system will not POST including after clearing the CMOS.Īs said in the previous post, whilst playing Guild Wars 2, in the middle of a world boss battle, my computer crashed, displaying a brown screen with equally spaced grey vertical lines and frozen sound. Upon experimenting with the many sticks of memory I have laying around, I have discovered that any memory, including multiple sticks I confirmed to be fully working prevent POST when inserted into DIMM slots 3 and 4 (The second color-coded bank). The other day I posted about an issue I had that turned out to be a dead video card preventing POST from initiating, where a RAM stick also prevented POST.

What slots does the ram go in
