Is my graphics card going bad ?

Berated · Sep 4, 2014

Two nights ago I went to turn my pc on and the monitor was showing "no signal " it was hooked up to the dvi port on my graphics card . Tried a new dvi cable and it still didn't work . So I tried my VGA port and it worked . Then last night I turned my pc on and my monitor went back to no signal . How in the world could my dvi then my VGA ports stop working within a couple days

Open up the computer and try unplugging and reinstalling the graphics card. With thermal expansion and gravity they can slowly work themselves loose. Always the first thing I try.

Can be a graphics card problem. Have you tried using built-in GPU?

M0j0jojo · Sep 4, 2014

Im leaning towards the PSU, It could be that either ur CPU or your GPU are not getting enough juice. My brother had the same problem, sometimes it would just happen at random times. If you can try to check your voltages in the bios

Yes , I took the video card out of the pc , cleaned it up (barely any dust ) and reinstalled it . The inboard video from the motherboard is working . I just don't get how 1 port could go then a short time later another port went .

@m0j0 I'm using a 500w power supply and it's a 2.2g core 2 duo chip with an nvidia gt520 card . I've never messed with the voltage before . Also this pc has had the same hardware for years now . Ther have been no recent changes .

M0j0jojo · Sep 4, 2014

Can you just check the Voltages just in case.

Berated · Sep 4, 2014

Yes . I can check the voltages . Never messed around with the bios before . What am I looking for ?

M0j0jojo · Sep 4, 2014

Go to bios, and then go to Hardware Health, it should say the 3V, 5V and 12V Voltages.

Berated · Sep 4, 2014

On the pc health menu it says

CPU temp 27c
System temp 28c
CPU fan speed 1415rpm
CPU vcore 1.296v
VDIMM 1.840v

I did this check with the monitor plugged in via VGA to the mobo

M0j0jojo · Sep 4, 2014

Did you scroll all the way down? cuz it should also say the 3,5,12 voltages as well, those are the most important as they will tell you if your PSU is giving out enough electricity to ur components.

Berated · Sep 4, 2014

Well here is a pic of my bios , it doesnt have the other voltages you had mentioned , I do have a program called speedfan and I think it is displaying what you were looking for on the bottom left.

those are the links to my bios and speedfan

Berated :

yup definitely the PSU your 12V rail is only putting 8Vs

Berated · Sep 4, 2014

Power supply ? Never would've expected that . So over time they can just put out less power ?

Berated · Sep 4, 2014

So my graphics card is more than likely still ok then ?

M0j0jojo · Sep 4, 2014

Yes because as you can see your System still runs, but after a bit its going to turn off because its not getting enough juice. so I recommend is getting a another PSU ASAP before the PSU causes any more damage to the components. My brother had this same problem, and since he procrastinating in getting another PSU his SSD died in the process. Anyways so he bought the EVGA 750B2, Johnny Guru gave it a 9/10 and its on sale at Newegg I suggest getting that http://www.newegg.com/Product/Product.aspx?Item=N82E16817438028&cm_re=EVGA_750B2-_-17-438-028-_-Product

Ok, think I'm gonna run up to my local micro center and pick up a new psu .

M0j0jojo · Sep 4, 2014

What is ur budget for the PSU?

Berated · Sep 4, 2014

I'd like to spend around 50$ or so . I built the pc in 2009 or so and I'm not looking to put much more into it at this point

Berated · Sep 4, 2014

Btw Ty for all your help so far

M0j0jojo · Sep 4, 2014

I would just get the Corsair CX430 for this build, as it doesnt seem power hungry http://www.microcenter.com/product/399979/Builder_Series_CX430_430_Watt_ATX_12V_Power_Supply

Berated · Sep 4, 2014

Ah ok , wasn't sure if I should get anything less than a 550 or 500

EasyLover · Sep 5, 2014

Better get seasonic/xfx series psu than cx430

Berated · Sep 5, 2014

Well I ended up picking up a brand new power supply this evening . Installed it and still no signal to my monitor . It is still the same 8v power reading as well through speedfan....
