Hi guys, 1st time poster...im having the weirdest problem...my pc works fine at my friends but when i bring it home (built at my friends) it gets to windows load screen and i get no signal on monitor and fans in pc go nuts (i think mainly gpu). The only thing that changes from my friends house to mine is the power points...my power points also work fine, even running my mates pc.


My specs: cpu i7 920 lga1366
Motherboard: asus p6t
Gpu: asus 560ti 1gb
Memory: 2x4gb ddr3 1333ghz
Psu: nexgen 650w, not modular.
Running: 4 case fans 9mm i think
Keyboard:Thermaltake challenger pro
Mouse: thermaltake theron
Monitor: Aoc 2434pw

Tries multiple power points, different monitors.

Ran 3dmark benchmark program thing on performance and its handled it fine at my mates, nothing overheating system works 100% fone at my mates

When you power on the system, try hitting F8 for boot options. "Enable VGA Mode" see if you can get into Windows via this mode.
I know it's working fine at your friends house... but make sure the 6 pin additional power connector is plugged into the video card.

Do you have an outlet tester? Did some cables come loose transporting it from his to your place? You might want to reseat the gpu.

I could be wrong, but nexgen looks to be a cheap psu.
The price for a 650w unit looks too low for a unit of decent quality.
It might have a problem if your power source is weak/variable/not grounded... etc.
Does your friend have a different psu?
Can you try a different psu?
If it turns out to be a substandard psu, do shop for a quality unit.

Have you tried bringing it back to his house and seeing if it works? If you've ruled out your house's power (the first thing you should do), then it's likely something came loose or has failed between his house and your house. Check all the power connections and failing that, the shoddy PSU is probably the first place to look. Even if it turns out to be a loose connection, I'd still return/replace the PSU as soon as possible.

Hi and thanks for the reply, the pc is 100% working fine. It boots and gets to windows 7 load screen, then its like a surge of fan power on the gpu then i get no signal, im leaning towards the cheap psu and the fact that i know im i old house with old power points etc
