Red Light Woes (hd4850)

[bojangles]

I had the same problem with the red lights a while back. My thread should be in the troubleshooting sub forum. I dunno... I just took it out everything from the case and tested it on a large box. Worked fine after that. Check for grounding issues in your case like pegs and dust. I'll find the thread when I get on my computer.

you have onboard vid?

just take out ALL cards then, it should boot into bios just fine regardless of settings.

just 1 stick of ram and cpu and NOTHING else...

Ok, new info.

I used a different PSU, same results. Then I removed the card and installed it in another computer, fans boot up on the card and the red light disappears. However still no visual, I tried using different ram sticks, but nothing.

I tried last night removing everything from the case and booting off a cardboard box, then completely reassembled the whole system to no avail.

Donimo- I'll give it a shot.

did it work on the cardboard box?

if it DID work you may have an issue with the mobo shorting to the case somewhere.

if it DIDN't work you can scratch that off the list as a possibility


My HP wouldnt boot when the psu started to go, took my x800 out of it and it worked into BIOS at least off the onboard.

I thought the vid card was toast so I ran it off the onboard for a month while I RMA'd the card, then the PSU went all the way and took my HD with it with all the pix from xmas... Not that that is your issue, just killing time till my shift is over.

Nope, no luck on the cardboard.

Just threw everything back into my old case/mobo/processor. Everything works fine, boots up no problem.

So far.

Ram is fine
Video Card is fine
Hard drive is fine
Psu is fine
Mobo?

So it isn't a shorting issue seeing as I have the same problem out of the case, Card won't work in either Pci-E slot. No luck at all trying to use onboard video..I dunno why the mobo would work one day then not the other if its the problem.

Maybe I should just rma it and go back to my phenom 9550 till it gets back...

[donimo]

process of elimination, if all the components work in the other system then the issue is with whatever was changed, ie: CPU and mobo.

its like sherlock said "if you elliminate the impossible then you are left with the truth" or something like that...

It "could" be the cpu, but I would lean strongly towards the mobo being pooched.

Also, the reason the mobo is pooched could still be the PSU so be careful when you use the psu on anything else as you may end up with 2 dead systems!

[aviduser]

Shouldn't I get some "beep" codes from the mobo if the processor is gone?

I'd be pretty dissapointed if it is the Psu, I dropped too much money on that thing just to have something reliable. Time to go pack up the mobo I suppose.

Try the 9550(or older AM2 chip) in the board,if it boots then you just need a bios update
if it doesn't then look like RMA time

[aviduser]

Nah, I already flashed the bios to the newest version, which supports the phenom II. I threw the phenom 940 in my old rig to test it and it works fine. In fact I'm using it as I type this.

I also tried installing everything outside of the case again, no luck. I can't see any blow capacitors or anything. Hopefully I can get it replaced or at least repaired.
