Glitchy boot screen, stuck in Windows 8 repair loop

Hi.

My desktop pc just crashed and is now stuck in the infamous "Your PC ran into a problem" loop.
At first, it just booted into a black screen after the Win8 logo. Following the advice of other threads, I tried resetting the CMOS; nothing. I then went into BIOS settings and loaded default settings. That made it get stuck in the repair loop. I've tried starting up in safe mode and system recovery, both of which did nothing. Safe mode gets me to the black screen after the Win8 logo. I tried resetting the CMOS again and now it's back to the black screen.

Furthermore, when I start my PC the bootscreen of my Gigabyte motherboard has these odd glitches, like dead pixels / digital noise. Could it be a problem with my gfx card? It's not completely dead, because I CAN see the Windows 8 repair dialogs.

Motherboard: Gigabyte GA-PA65-UD3-B3
Graphics card: AMD Radeon HD6700 Series

Thanks

It's the card. When you see corruption outside of Windows, you can eliminate driver problems. It can either be overheating or power issues. If you eliminate those, it's almost the card 100% of the time. You don't often see PCI-E ports act up. The PCI-E lanes are built into the CPU now, so you can usually eliminate the motherboard. Not alway but usually.

Since your computer works with a different card, it's time for an upgrade.

Let us know what your budget is, and we can throw out some suggestions.
If you are seeing screen corruption outside of Windows something is wrong with your display adapter.

How long has it been since you cleaned the heatsink on your graphics card?

Also check make sure your PCI-E power connectors are fully inserted into the card.

There is also a possibility your PSU is failing, but I would look at the first two first.

Okay, so I tried cleaning my card, although it's not that old so there wasn't much to clean. Nothing. I then tried a different PCI-E connector. Still nothing.

I the tried troubleshooting a bit. First I replaced the PSU. That got me a little further. I can now boot up in safe mode and when I don't, I get as far as the login screen, before it goes to black screen again. I then tried with a different graphics card. I can now start my PC! So I guess the problem is with the PCI-E port on my card or something?

Oh well. Guess it's time then. It was a bad card anyway.
Some recommendations would be nice. I had Asus GTX 760 recommended to me and that + a little more is my price roof.
 
I bought my son the ASUS Direct CU 760GTX, great little card.

However if that is out of your price range, you could have a look at the 750GTX or 750 Ti. Decent cards, low power usage. The vanilla 750 comes in around the $150 mark, the 750Ti comes just under the $200 mark depending on the manufacturer and pre-overclock. Of course these prices are CAD, if you are in the US, it'll be a little less.

My AMI Bios troubleshooting and system diagnosis reported System Memory Failure. This was on an HP d5000t with ASUS motherboard. 1 Gb Hynix sticks were mixed with 2 Gb Samsung in each memory bank. After removing the Hynix, the system booted normally. There is some really flaky memory out there. Sounds weird, but it fixed my problem. I will no longer mix memory manufacturers. Have just ordered 8 Gb of Crucial memory in case the Samsung and Crucial are not compatible.
