Hi
You may have already read a thread from me posted a month ago about an issue i had with a newly acquired GTX 750 it. I thought it was solved since then, but in fact, it's not.
Here's a recap:I've bought a MSI GTX 750 ti (without PCI-Express connector, only powered by the PCI slot) to improve my PC (based on a motherboard Gigabyte ga-ma785gmt-ud2h rev 1.1, roughly 5 years old, and an Athlon X2), play and mine a bit.
At the time, my PC was booting and was even reaching windows (i know it as my wifi dongle is only turning on when windows has started), but without anything on screen. I was using a HP 300w PSU, so people on this forum have advised me to change it for something more powerful and stable.
I've purchased an Antec 600w bronze PSU, and then the GTX was working. Nonetheless, since one month, every now and then, i had the same issue that with my old PSU, the PC boots but without anything on screen. I am generally able to fix this by unplugging/plugging the components inside my rig.
I thought this issue was again deriving of the PSU (it was emitting an annoying hissing/rattling noise), and changed to a 550w platinum of high quality, but this time, the GTX wasn't displaying anything. I switched back to the Antec PSU and it worked 70% of the time as explained.
I have dealt with this tiresome situation until today, when regardless of my manipulations, the PC boots but i don't have an image. I'm currently using an embedded graphic chipset in my motherboard as a last resort while trying to resolve this problem.So, what do you think is the issue?- PSU: At first, i thought it was because of that, but i have the same problem with three different PSU, 2 news with a power above 500w which is more than enough for my rig (my CPU is like 60/70w, the GTX 750 ti is 38w and Nvidia recommends a 400w PSU).
- The GTX 750 ti: It's brand new, and when it worked, it worked fine (good performances, no artifacts). But i'm wondering if i don't have a semi-defective unit. When checking the back PCB, there are some "strains" around some chips, wonder if it's normal (not burns, just light strains).
- The motherboard: it's 5 years old, i'm wondering if it's not too old to handle this recent graphic card, especially as it's only through the motherboard and the PCI slot that the GTX is receiving its power. Perhaps the MB isn't reliable/stable enough in that light (although even if i don't have an image on the screen, the GTX fans are turning which would mean it's at least partially powered). I've tried another CG (an old radeon x1600 hypermemory), and it's working, so not sure if it's coming from the pci-e slot. Note that the MSI card is very long and hit a heatsink (but it hasn't prevented the card to work, when it worked). Concretely, do you think it could come from this motherboard? Are there any reported similar issues when we combine these kind of motherboards and brand new graphic cards?
So i'm a bit lost here, i would like to avoid sending the GTX for an RMA if the issue isn't coming from it. I may also buy a cheap micro atx motherboard and a new CPU to spruce up my rig (preferably intel isn't it?) but not sure it's the right time for this and what to acquire (and perhaps the issue isn't coming from my satisfactory enough mb+cpu).
Thanks in advance for your help
