[HELP] My PC shows No signal to HDMI - with youtube link

[Squimoth]

Specs- http://www.scan.co.uk/savedbasket/ba366941b617466eb48af...
Running Windows 7 SP1
This is a post after many others which haven't helped. A few days ago i (posted on reddit) http://www.reddit.com/r/techsupport/comments/1g7a80/urg... and then thought i had solved it by taking out the drives and plugging them back in. Then the random and often bluescreens came back and i was memory testing and one of them (RAM) was fine (from what i see). Plugged the other RAM in and it didn't work! Now it won't work. I have no signal to my monitor again. And i really need my computer back! It seems to boot as usual like before i fixed it the other time which is strange so here's the video on
Youtube link - http://www.youtube.com/watch?v=gL0J2bv4vIQ

Steps i have tried:
A Different HDMI Cable
VGA through Motherboard to a different PC
Reseating Ram
Unplugging Drives
Unplugged all cables in Motherboard and put them back in.

Hello Squimoth, welcome to Anandtech! There are a lot of knowledgeable people here, so let's see if we can figure out what is going here.

First of all, I don't totally understand what is going here. The reddit site is a mess, and the link to your system specs doesn't work, so listing some specs here would be a great help.

I think I see over there that you replaced or reseated some RAM, and now your display doesn't come on through HDMI. Was anything else going on at the time? Why did you have to mess with the RAM? Had you installed any other new hardwre/software at the time this happened? Do you ever see anything on the screen? Was this the original RAM or different sticks? In other words, talk to us like this is the first time you have reported this issue.

Without answers to these questions, I can only recommend that you check and make sure the clips on the memory and grabbing the RAM like they should, check the 2 power connections on the motherboard (24-pin and 12v 4or6-pin by the CPU), and the power connector on the video card.

Start with the basics. Board, Chip, one stick of ram and using the onboard video. If no video, try turning it on with no ram. You should get an error beep code. If you don't then you have a bad board or a bad power supply.

What don't you understand? Specs - i3 3220, XFX Radeon 7770 DD, B75 Mobo, 8GB Corsair Vengeance Ram, Corsair 430V,

Nothing was going on, I had many bluescreens and one i specifically remember saying memory management so someone told me to reseat. I Don't see anything! Original RAM... this is the original post

'Solved: I took out the HDD and odd cables and it booted without so I tried without odd and it seems to be back to normal... Thanks everybody. Not going to plug odd in and I'll post again if needed!
Basically I posted yesterday about BSOD'ing all the time. I thought i'd solved it when it did it again and crashed my League. So i thought f*ck it and reseated the RAM. I did it very carefully and i thought it'd be fine and now it will not come through to my monitor and it seems to be booting properly. Getting very worried! Please Help!

But that's what solved it the first time. The RAM Looks fine! And power connections too!

Tried onboard video and no RAM and there's nothing!

If you are down to just the board with no ram and you don't hear an error beep code, that narrows it down to board or power supply. My experience has been about 50/50 between the two however a power supply is the easiest to swap. If you have ruled out the power supply make sure you take the board out and test it out of the case to eliminate a grounding/short issue.

Hi! Erm me and a friend built the PC and i'm unsure whether the speaker cable is plugged as i get no beep with no ram!

 

[Matt1970]

It's been a while since I saw a new board without a built-in speaker but yes, make sure the speaker is plugged in. If it has the speaker soldered to the board it should look something like this:

Right i'm really confused because my Grandad just reseated the RAM again and voila it boots! Going to wait for it to bluescreen now! Will you guys be able to help me diagnose BSOD problems?

 

[Matt1970]

Well that makes me lean towards what ketchup said that maybe one of the ram clips wasn't locked in.

maybe though ive done it lots of times and im sure one of them is not working according to windows memory diag but im scared to take out now!
