MSI 870A-G54 No video...

Hi Guys,

I've been cleaning all the dust out of my computer today and also gave my cpu some fresh cooling paste. I've moved the power supply, memory banks and gpu in and out of the case to do so (and so disconnected them from the mobo). I also installed a new SSD on a unused sata port.

However... when checking if all looked and sounded right when booting up - which it initially did as all the lights were on, all the fans are working and I can hear the hard drives booting up fine - the video never came through... I initially thought it might just be some dust stuck in the PCI slot so I removed the GPU again and tried making sure the connection was right. But still nothing.

To rule out a broken GPU I borrowed my friends gpu to try and see if it'd pull of a video signal this time, but no luck. I also tried resetting my mobo's CMOS with the jumper and disconnected the new SSD and other external hardware. I've got all video outputs (2x DVI, HDMI, Displayport) covered with different monitors to make sure I'm not missing the signal on a different output as I had this once before.

I fear that something somehow got fried, but is that even possible? I certainly consider myself a gentle cleaner when it comes to touching computer components... A static energy discharge is ruled out as well (I make sure of that always).

Any ideas anyone? Or maybe even a possible solution?

Tech Specs:
MB: MSI 870A-G54
CPU: Athlon X6 1055T
GPU: XFX Radeon 5850

Oh yes... and then there's this strange involvement of this plastic cover thingie on this picture here...

This was laying underneath my GPU when I took it out the 1st time. I can't imagine it could be involved somehow. But on the hand... I have no idea what it is or where it came from. It's around 5 cm's / 2 inches long.

Any answers would be greatly appreciated :)

It looks like part of a PCI slot, there should be three of them on yor motherboard, check to make sure they are all in place. I hope you had the video card installed in the PCIe slot nearest the processor (BLUE Slot).

They're all in place and they seem fine. I tried moving it around but it doesnt seem to fit as something that was previously attached anywhere...

And yes, the GPU was installed in the upper blue slot, closest to the cpu. Which was the only 16x PCI-e on this mobo anyway.

I'm becoming more and more desperate here as I've also got a RAID-0 array set-up on this mobo... I fear for the data on it. If anyone has any ideas on how-to save the data, I'd love to hear those too.

I found the answer:

After a whole series of numerous tests it appeared that both a single RAM module (1 out of 4 total) had a defect, causing the entire system not to boot. The other modules appeared to be fine after running some tests.

But... the CPU also turned out to have a defect. As the system would only boot if either slots 1 or 3 or both were used. As soon as any module entered slot 2 or 4 the system wouldnt boot. I initially hoped that it was the mobo that had the defect as obviously it's cheaper to replace, but it turned out to be the CPU. I'm not sure what exactly went wrong with the CPU but apparently it's no longer capable of booting in dual-channel ram mode. So I replaced the 1055t CPU with a different AM3 processor and all the RAM slots kicked back into action with no errors whatsoever. So I'm going to RMA my 1055t and in the meanwhile I've ordered a new Asrock 970 Extreme4 mobo to go with my new AMD FX8350 B.E. CPU.

I can vouch for the ''POST/boot/no video steps'' topic, it helped a great deal and made me look at some things I hadnt thought of yet :).

Thanks for the support guys!
