[SOLVED] HELP! : PC Will only boot with my old graphics card

[George521dj2]

Hi there,

Last week I went to turn my comuter on (which was running a gtx1050 at the time), to which I discovered that it would not boot. The system had been working fine for a year before but when I turned it on there was no beep from the motherboard and no display whatsoever ( not even the bios screen ).

So I tried resetting the CMOS by taking the battery out for 15 seconds, but it still wouldn't work. I also tried uninstalling all of the display drivers using DDU before putting the card back in but it still didn't work.

After testing the other components in my system, I finally decided that the gtx1050 was broken and put my old AMD Radeon R7 250 back in - which worked.

I ordered a gtx1650 super to replace the card and when I put it in the system, it did the same thing as the 1050.

I am currently using the r7 250 to use my computer to write this post and it works fine but it won't even output a display with either of my NVIDIA cards.

Any suggestions would be greatly appreciated

My specs are:

CPU: AMD Fx-4300 Quad Core

GPU : Currently AMD R7 250 - ( the gtx1050 and gtx1650 super would not boot).

PSU - 550 Watt

Memory - 2 x 4gb DDR3 Kingston HyperX

Motherboard : Gigabyte ga-78lmt-usb3

Hey there,

Hmmm. That's a tough one.

My first answer would have been that older mobo's like that without a UEFI bios often have trouble with newer GPU's. Specially cards from the AMD RX4xx/5xx and Nvidia GTX1xxx/2xxx series cards. Anything before that seems to work okay.

However, you've said the GTX1050 did work, so that's why I'm scratching my head a little. It might be worth updating your bios if you haven't already done so. That could kick it into gear again.

The only other thing I can think of is the PSU. What make/model is it? Although the R7 250 and the GTX1050 are only 75w they don't need a 6 pin connector. The GTX1650 is a 100w part and requires a 6 pin connector, so it may be the PSU just isn't working correctly and providing enough power.

Can you confirm he power cable going into the GPU is in right?

Hi thanks for responding,
My psu is a Winpower plus 550w. The 1050 used to work but last week just randomly stopped working and my pc wouldn't boot. The same thing is happening with the 1650 super

Have you another PSU you could use/borrow from a friend to test?

No I don't 🙁 . My friend has tested both the gtx 1050 and the 1650 super and they are both working. Obviously due to the current circumstances it is difficult to borrow a psu. None of the lights to indicate lack of power were flashing on the graphics card when I tried soI'm not sure. Do you think that it is more likely to be a faulty psu than a problem with the motherboard?

 

[Roland Of Gilead]

It certainly could be. That PSU is not great at all. The cards may work on your friend system, if his mobo is a little more modern. Did you confirm if the cable from the PSU was connected to the GPU's correctly?

Could be worth trying a new PSU, but if it's not that and you spend the money, you are back at square one.

I don't think it's a mobo issue, but, rather a bios issue.

If it's a bios issue then how come my 1050 used to be running fine? Thanks for the help

Also the cable was connected correctly from the PSU to the GPU. The 1050 doesn't require external power from the psu

Yes, I mentioned that, it's very unusual.

Okay, that what I hoped for. Is it a full PCIE 6 pin cable, or one done with a connector?

Yeah it's a PCIE 6 pin connector

You might try and clean out the PCIE slot with some compressed air. It could be a bit of dirt on a contact stopping it form working.

I bought a new PSU and it still won't work. Will try this but I doubt it will do anything.

I only did a quick search, but if this is the PSU:
https://www.amazon.co.uk/Winpower-Plus-550w-SATA-Molex/dp/B01K7H1432

Then in the blurb, it "brags" about the 12V rail having 25A available. That's only 300W total for the 12V rail, ergo, realistically, it's a 300W PSU. I would definitely change that out ASAP. See the first link in my sig for a guide to picking a high quality PSU.


EDIT: just noticed that you bought a new PSU - what brand and EXACT model number is it?

I bought an EVGA 500 W1, 80+ WHITE 500W, Power Supply 100-W1-0500-K3

At this point I'm just going to build a new PC as I believe that there is a problem with the motherboard.
