Hello, I've had my PC for about a year now and never had any problems with it, but in the last week when I turn it on the cpu light flashes, all of the fans spin but it won't boot, the only way I can get it too boot is my pushing down on the cpu AIO block, I've treid taking the ram and gpu out, switching the ram, checked for bent pins, checked the 8 and 24 pin connector, still no idea, can't imagine anything is dead and I can get it to turn on sometimes
