I'm really sick of my PC and I'd love to throw it off the 5th floor but unfortunately I don't have this luxury right now.

The issues started when I moved to a new house about 2 months ago. I didn't have this problem before.

Case: Arctic Cooling Silentium T1 with embedded Fusion 550 Eco 80 PSU.
M/B: ASRock A790GMH/128M
Gfx: ATI Radeon HD 5770

Here's what's happening almost on a daily basis:

I wake up in the morning, switch on the PC and all the fans start spinning. 9/10 the graphics fan stays on 100% and I know it won't post. If I'm lucky, ATI's fan stays on full power for a second, then goes back to normal and I get a normal post but that doesn't happen often.

No, instead it's just drives me crazy. When I get no POST I'm trying a lot of different things and what bothers me the most is that they all work. But not always. No... That way I could find out what the hell is going on and we don't want that.. right?

So, sometimes it manages to POST if I:

• remove the keyboard
• remove the power cable for a few minutes
• remove the graphics card
• remove the HDD cables
• do nothing, just turn it on and off a few times

Sometimes it doesn't POST even if I do all of the above. And I end up removing all power cables from the M/B, and connecting all the stuff one by one. Sometimes it works, sometimes it doesn't and I just have to pray and wait.

What the hell is that? I'm getting pissed of again just thinking about it. The only solution is to leave it on 24/7 but I don't want to do that. It should be able to turn on and off when I press the power button. I'm not asking much.

I'm starting to think there's some weird electricity/power issue but I really don't understand what it is. There's no logical explanation about it. At least I can't find one.

Any ideas?
