Leadtek TV tuner problem

Hey everyone a couple of months ago i bought a new computer, new everything.

Phenom ii x4 840, gigabyte hd 6870, 4 gig ram, asrock 880-gm-le (mini board), neo eco psu 520 w

and as of yesterday this product http://www.umart.com.au/newindex2.phtml?bid=2

so i installed it and the first thing i noticed was how extremely close it was to my GPU, simply because my GPU is huge. However everything works fine, but when i choose to enable hardware acceleration, after about 5 minutes my PC will reboot. I have checked the temps of the card and they stay below 40 despite rising somewhat with hardware acceleration on.

Could this be PSU problem? I thought i had a well decent PSU for my requirements. Could it be the GPU and tuner card are physically touching causing problems? (i doubt it because it runs without a hitch without hardware acceleration). Or could it be something else like my new 6870?

Lastly, i do notice an increase in quality when enabling hardware acceleration, so it would be great to get some assistance. thanks

If temps are ok it could very well be PSU problems.

Antec Neo Eco is a prerry cheap psu and 520w is a little on the low side even for a good psu.

If you have any unneeded devices (hdd's etc) unplug them and see what happens.
Everyone will tell you 520w is enough, and yes it is. But a 520w PSU produce 520w of constant power.

If it is your PSU, id suggest a good brand and ~750w. After i moved up from 650w, I could drop my oc voltage. My psu runs cooler, quieter and will last far longer.

ok thanks man, it could very well of been my psu because it was the first thing i suspected as well, however, since trying today, i have had no such problem with hardware acceleration being enabled so will wait it out a bit

I highly doubt that your Seasonic made Antec Neo ECO 520 is the problem.

The Antec Neo ECO 520 should be capable of providing its labeled 40 Amps on its single +12 Volt rail.

The Radeon HD 6870 has a maximum board power of 151 Watts under full GPU load. This means that it will draw up to 12.6 Amps from the +12 Volt rail.

A TV tuner card draws little power.

Your power supply unit is more than capable of powering your system.

So firstly, why is my computer using a windows NT driver? Is that the problem right there?

Secondly, this person is experiencing exactly what i am experiencing however my pc will hang and then restart every time.

It definitely appears to be a conflicting driver problem
