I recently upgraded to windows 8.1 and upgraded my tablet with a 62 gb ssd hard drive with no issues. I then installed a pny 8gb ddr3 pc3 12800 memory chip and my computer has gone through a series of blue screen failures. It has booted twice with the 8gb memory stick installed, but eventually shutdowns with a bsod and goes back into the reboot cycle of trying to solve the issue. My question is did I buy the wrong memory stick since its a pc3 12800? It says its compatible with the 1600mhz, 1333mhz and 1066 mhz. Please let me know if anyone has any solutions.
