Wont boot with Graphics Card

Hello guys.

New poster here but always on the site..

Basicaly I purchased a new graphics card yesterday from OCUK. After installing drivers everything was working fine, I was very happy. I played a few games for a test and everything was running smoothly. So turned off the PC at night..the next day went back for some gaming, still everything is fine. After turning off my PC today and going to work for 4 hours I got home hit the power button.. and nothing. No signal or boot bleep. So I manually powered down then hit the power button again, this time it works so I thought id shutdown and try again just to make sure.. this third time same again, no boot up but the fan is still working.

After taking out the GPU and inserting again I realised the 6pin to molex was a little fragile and one cable was very loose. So I gave it another fire up with no keyboard or mouse and everything started up fine. But silly me had to restart to plug keyboard/mouse in.. after the reboot again nothing no boot screen just no signal on monitor and no sign of loading?

I then inserted my old GPU which is terrible, but that works perfect. I am very confused as to how sometimes it will work and be fine, but then other times I cant even get a boot? Faulty?

Can anyone help me out? Is this a problem with the GPU power cable? My PSU is 550w so meets minimum. Or do I need a card replacement?

Thanks, if you need anymore info just let me know and i'll try my best.

Sound like you could possibly have a dodgy card to me. Had the same issue with a previous card; worked fine for a few days then wouldn't power on with it plugged in.

Sounds like an RMA job!
 
If the old GPU worked fine with the 6 pin to molex... I would say the new GPU is suspect. One final check before RMA would be to try another 6 pin/molex cable first to eliminate that possibility :)
 
I would recommend trying the graphics card in another PC before RMA and see if you get the same problem. Also what make is your 550w PSU, because if it's a cheap PSU it won't be kicking out 550w.
 
Could be motherboard, i had a similiar problem awhile back and it turned out to be the pci-e x16 slot.
 
Agreed, try in another PC if you can, and try another PSU connection.

I however suspect it won't be the slot if one card works and the other doesn't.
 
Thanks for the replies guys.

Just about to head out for a new 6 pin power connection. I'll also try the card in the my friends PC. And the crappy old graphics card I have in now doesn't actually require the 6 pin so it could well be the cable which is causing this.

I'll post back later with my results.

The make of my PSU is R-Senda.
 
HIS ATI 5750 512mb. But like I said, I had no problems for about 2 days.

2/10 times it will boot up perfectly?
 
Yep cheap PSU, would not suprise me if this is your problem. Bet you would be lucky if it kicks out 400w constantly, never mind 550w.

Solved.

Well the new 6 pin worked a treat. Obviously was sent a crappy cable, oh well.

Thanks a lot for the replies and I'm also looking into a new PSU which I will purchase next pay day.

Thanks
 
Have the same problem as you, will boot to onboard some times and to graphics card sometimes.

Really weird suspect nforce pcie 1.1 to be the number one suspect, considering it is quite old and people had problems with 5k series let alone the 6k series, anyhow going up to the overclockers shop some time to test what the problem is.
 
I just managed to get 3 boots out of it in a row..

I have a friend telling me it could very well be my motherboard.
 
Well after using the card in a friends PC with the exact same setup I have the same issue.

I am going to be looking at a return so I can exchange for and alternative (same as my friends)

Is this an option after unboxing the card?

That could just mean the cards faulty?
