This is my first post on these boards, they always pop up in google when im looking for computer help so i thought i'd give it a go.
Here's my problem, I was hoping you could help me with:
I just bought a new PSU a week ago, switched from my Corsair tx650w V2 to a Be-Quiet Dark Power Pro p9 650w.
The first time i switched on the computer with the new psu, it wouldn't work. All the fans started, including the GPU fan, but the monitor (a 42" LG tv) said "connecting...no signal".
So I restarted the computer again, and this time it worked. The same thing happens about 1 in 5 times when starting the computer.
I noticed that whenever it fails to boot, the DRAM LED on my motherboard doesn't flash...Edit: It actually did flash the last time and still failed to boot, however there's never any activity from the HDD LED.
Also, after a period of inactivity, when i switch from the tv to the hdmi port on the tv display, the monitor gives me the same "connecting...no signal" message, until i move the mouse, I dont think this happened with the old PSU.
I'm not sure where to go from here, I've contacted the Be-Quiet tech support, but haven't gotten an answer yet.
Is this problem most likely due to a faulty PSU or are there any settings i need to adjust? This PSU is modular unlike the last one.
Ok, so I've had the old power supply in since yesterday, started up the computer a number of times without any failures.
The only difference between the setups, is that i use 2 molex connectors to the GPU with the Corsair, and one of the case fans runs on full power, also with a molex connector.
The B-Quiet one has its own fan contacts which i used for that case fan.
None of that should make any difference, should it?
