Pc freezing with discrete works fine with integrated

I see your build in your sig. What is the make/model and wattage of your PSU?

Sounds like a Dying video card, Whats the power supply that you're using?

thenks for the fast replies

I'd almost bet my next paycheck that's the issue right there. Do you have a friend or someone you can test your video card with? If not see if you can take it to a local pc shop or best buy and have them test the vid card before getting a new psu.

well I am almost sure it's the psu cause the gpu temps are fines and since the problem started I tried it a couple of times and it ran well but after few minutes it freezes or crashes

and I have been running this rig for a year if it matters

Best bet would be that PSU. I would get that thing replaced with a quality PSU ASAP before it takes the rest of the system with it. That is if it is not already to late. It should be illegal to even sell PSU's like that.

hehehe
thanks for the replies
do you have a good psu in mind less than 40$

A Corsair CX430 should be fine for your needs: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Lol personally i would go for the XFX core edition psu same price just better build quality and better looking. For your information i'm facing the same problem and i'm pretty sure its the graphics card. My system freezes when gaming and have to switch it off manually (won't let me go into task manager)

well is there a way to be sure of the cause of the problem

Yup. Test the psu and graphics card in another machine. Thats about the only way to be certain besides replacing parts. Personally and not trying to discredit him but... I don't think Haider is correct. All signs point to the PSU and it's not exactly a reliable one  .

If.. it does end up being the card. Replace that psu anyways. That is the heart of your system and when a psu goes... (especially non quality) they can take other parts and sometimes the entire system with them.

well now I tried to boot with my discrete card and nothing shows up and after few seconds the pc automatically switches to integrated graphics , is something wrong with my GPU or it has to do with the PSU

lol whats not correct? i didn't even say anything significant haha. Im 80% sure its a PSU problem cause i'm facing the same issue   Replace it before it kills the system entirely.

Make that a 100% Besides he needs to replace the PSU anyways. I would NOT trust a generic PSU (already made the mistake once running a 9600gso on a generic 250w psu haha)

I thought that you were saying it was the graphics card due to this statement. "For your information i'm facing the same problem and i'm pretty sure its the graphics card."

I apologize if i read it wrong. Wasn't trying to offend, was just stating I didn't feel the card was the issue. Regardless... To OP a quick test of the card in a diff system will give you the answer  .
