Little issue with my video card (Radeon HD 6xxx Series)

But I have to say the card does look very suspect I don't know what Boozad thinks he is probably more experienced with those.

At this point I'm inclined to agree, if the PSU test proves to be OK I'm pretty much running out of ideas.

I think its a overheating issue due to the fact the 4 grey pins on the gpu gets burning hot within 10 seconds of the pc being on.

WHOA!! that is a real problem mate the cables / pins should get warm but hot relates to me to something shorting out in that card.

Have you got a multimeter you can stick across the pins and measure the resistance that should show up some are zero full on open circuit and some should show varying resistances.

Then get onto a board hold down screw (ground) and then touch the socket holes it the card there should be two that are a direct connection (zero) and some again that show up varying or no connection at all.
In all probability this card has some serious problem within it. Without going all the way back have you or anyone had this card apart - it isn't hard to do and check out for any evidence of overheating or caps that are damaged bulging, splitting etc Of course the really obvious is the fan able to spin.

There's no point anymore, I threw the card away and got myself a Radeon HD 7750, with a new power supply (To stop the random restarts).

I should get it Tuesday so I'll post back with the results when I get it.

No probs mate hopefully this will be the end of your tribulations. But do let us know how things turn out.

By the by if you are inclined I would take that puppy apart and just see for yourself it might come in handy in the future - but there again I am a predictably curious and pedantic sort of errrmmmm alien LOL!!

No worries mate as before hope the new one works ok:)

Without wading all the way back did we mention this

PSU - Jump Start

then this is a really good reference to keep

Power Supply 101: A Reference Of Specifications - Power Supplies

this will give you most of the gen on volts etc.

Now you have to keep in mind that correct volts do not necessarily mean correct current ie the 12v rail is probably the most important rail and it might show up as 12 - 12.2 v or conversely it might fall below 12v. There is a discrepancy of 5% +/- for the output voltage.

So for example 0.6v is 5% of 12v therefore 11.4v would be under voltage and 12.6 over. Either way it is not good for the machine as the leeway as you can see is fairly limited.
Plus you have to remember too that these days we are using much smaller architecture hardware that in turn uses decreasing voltages and I am sure you know that even very small changes to the volts can have a great effect on the frequency of the CPU for example.
So having the PSU operating at the optimum levels is most important and something that a lot of people (as Scott Mueller if you have ever heard of him states) seem to overlook as a primary cause of machine failure and that he deals with more problems with PSU failures than almost anything else.

At this moment I have a tester machine wit a PSU that is reading 11.2v on the 12v rails and am having to replace it with a recycled one from another machine because the case fans which I hadn't noticed previously were running very slow and therefore causing some overheating issues with that machine.

Now I am sorry if I have gone on a bit but I do end to get carried away but I hope this is of some help to you .
