Hi friends. It happened this way today, after upgrade of my PC new strip of RAM at 8 GB, the computer ceased to understand that is when you press the power button everything starts up (coolers, hard disk drive, all the lights are on) but the screen is dark and the computer did not ship. Thought not themselves compatible RAM, but there's a caveat, when you insert the strap I cleaned the PC and changed the thermal paste and before I push it back, it's hooked up to check that whether the strap and the computer was loaded and worked fine - 1 time. Aida showed 16 GB. But after all stuck in the housing and turned, the computer ceased to boot. When one pulls the bar, it starts to boot and work. Just tried to run the computer on one plate, then insert the other when it is enabled, then restart, and then also the RAM works and all programs show my 16 gigabytes, but once off, then again it is not loaded. What could be the problem? If the RAM was not compatible, they probably would not have worked at all or am I mistaken?
