Motherboard: MSI H77MA-G43 1155 socket. Alternative motherboard: ASUS H61M-K 155 socket CPU: intel core i3 3220 3.3ghz dual core. PSU: Intex AC 230v Alternative PSU: older. 400 watt. ~220v - 240v. GPU: Nvidia geforce gt240 ddr3. RAM: Apacer 4gb UNB PC3- 10600 CL9 (not sure what specs to give) A week ago I made a wall mount for my pc. In the weeks leading up to the mount going up my components were just scattered across a table (everything plugged in and working, just not mounted on anything). When I tried to switch the pc on after mounting it, it started power cycling without booting or displaying anything on the screen. I unplugged each component one by one to determine what was wrong. I also tried another PSU. Eventually only the ram was plugged in (by this time I had the screen connected to the on-board vga port). It still did the same. Without RAM or the CPU, but a cpu fan, It does not power cycle. It also does not beep for a ram error without a cpu though. Before I realized it does not cycle without a cpu, I got a new cheaper MB online, an ASUS H61M-K. With the CPU in this MB it does not power cycle, but I still don't get any output to my screen via either the graphics card or onboard vga port. My gaming keyboard also does not light up. can I assume the cpu is broken and buy a new one?
