815612 2009-09-30 20:08:00 Hi, I can't understand what's happening to my PC. I opened the case of my PC and gave it a blow clean. After that, I tried to restart as normal but found it has no power to keyboard, mouse and monitor. There is power to my HDD, front LED light, fan going and beeping sound. I googled search, and some said it is PSU is playing up. But I used another PSU to power it, and problem still the same. I also used took this PSU to other PC, and it is fine. Is my mobo (GA-8IPE775-G) the culprit? Please help. Thank you in advance. ahd8888 (184)
815613 2009-09-30 20:17:00 Are all the plugs still in nice and tight inside the case on the motherboard gary67 (56)
815614 2009-09-30 20:23:00 You say no power to the monitor... the monitor would normally be powered directly - can you clarify this please? inphinity (7274)
815615 2009-09-30 20:25:00 Yes, I have check then over and over again. I am sure the power cable from PSU to motherboard, HDD and the cpu are pluged in. ahd8888 (184)
815616 2009-09-30 20:27:00 What I meant is the little light on the front of the monitor stay orange, instead of green. The Cap and Num LED on Keyboard won't light up. I have tried the PS2 keyboard and mouse, instead of USB ahd8888 (184)

Sounds like one of three things.

1- Faulty Motherboard
2- Faulty/unseated RAM
3- PSU issues.

A great first step is to do this:

Unplug any unnecessary cables and PCI cards from the motherboard, eg hard drives, optical drives, front USB/firewire, modems, graphics card, that kind of thing. Just leave the power connectors and the front panel connectors plugged in. (And monitor/mouse/keyboard obviously.)

Remove the RAM and power on the PC. It should beep at you like a mad thing. If it beeps - good. Put the RAM back in and try again. If there's no beep, you're down to either the motherboard or PSU at fault. CPU failures are one in a million. Due to what you've done, I would expect it's just the RAM has become unseated and needs removing and replacing.

Are you using a graphics card or onboard video?

Try that and post back with the result.
