What are all your system specs..PSU wattage and what is the GPU you have now?

His psu shouldnt matter, hes using a 9400gt. That should run on any crappy psu.

Also if your cpu doesn't work, then you cant even boot to the bios. You need to get a new cpu first.

It would matter if it does not have PCI-e connections for his new GPU

i need to know what is to blame before i buy new parts.

many things can cause the symptoms you are displaying. Since you bought a second had GPU, it could be that. It could be the PSU or MB as well. do you have any way to test the GPU in another Machine?

 

[Guest]

No i do not ive tested differ gt 430 on this mobo with different psu

 

[larrym]

Did the other PSU and gt 430 work?

 

[Guest]

Yeah prfectly

 

[larrym]

can you test the 9400 with the other PSU?

 

[Guest]

I tried a 300w psu and same result

 

[larrym]

Since other components worked, that tells me your MB and PSU are fine. And since the CPU you bought was faulty, and you bought the GPU from the same guy, well it looks like the GPU is bad as well.

 

[Guest]

And i tried with a underpowered 250w

 

[Guest]

Ok so faulty gpu can make hole system fans to spin max?

 

[larrym]

Yes, It can do all kinds of things. Since your system works with another GPU (GT 430) and not with the GT 9400, and you tried multiple PSU's, then I would say your GPU is at fault.

 

[Guest]

Thanks can u suggest a cheap gpu cheap but capeable

 

[larrym]

what is you budget and from what country? And what PSU will you be using?

 

[Guest]

Uk and ordering a cheap psu tomorrow 750w on ebay tomorrow, and 100

 

[larrym]

Don't get a cheap PSU, meaning quality, not price. What is your total budget for a psu and GPU?

The PSU powers your entire system and if it goes, it can take everything with it.

 

[Guest]

30 for decent size psu
