DarkFire989

I just installed yesterday another 6970 into my computer along with an LED kit. I was playing BF3 today for about an hour and everything seemed to be running smoothly. Got off of BF3 and was just browsing the web. Then all of a sudden my PC shuts down, I hear a loud POP sound come from it, a burning smell, and then my PC turned on again. I think it was my Power Supply. It's a Corsair HX750. I did a lot of reading saying that this should be OK for crossfire but I am not sure. I'll probably have to get ahold of Corsair tomorrow.

I am not sure its the PSU but I am almost positive. It is not dead though since the PC started back up again and it did not BSOD.

I'm scared for your motherboard. Impossible to diagnose. Most likely the PSU, but can't be sure.

Lunchboxer

Do you run an UPS?

DarkFire989

No I don't LB.

Foxy wouldnt it have BSOD when it turned itself back on again if it was the Mobo?

DarkFire989

I am looking all over for burn marks or smell but I am not finding anything.

Lunchboxer

Hopefully it was just a small surge that hit the power supply but nothing else.. hopefully...

DarkFire989

I will run a surge protector in the future now though.

Lunchboxer

Yeah, I run a good UPS even on my really crappy desktop...

DarkFire989

Can I trade you my simple power strip for yours

If you don't see evidence on the motherboard of a failure then it is probably inside the power supply. Judging by the pop and how it seems unaffected you blew a capacitor which is common if you have a non solid state capacitor that's past its prime.

DarkFire989

Thanks bud. Would you suggest RMAing it?

Lunchboxer

Ha!

I have this one, it is pretty sweet!

DarkFire989

Yeah..... Im not gona spend 180 on one of those! I looked into the PSU with a light, i cant open it cause I'll void my warranty. I didnt see any blow capacitors but my Mom said she could smell something burnt. I will call corsair tomorrow. And probably just order the HX850 off of Amazon, then sell my new HX750 when I get it back.

If it has warranty and served you well for years then I would RMA it. If it's only a few months old and this happened I'd just not take the chances and buy another brand. It could do some real damage next time.

I'd bank on it being the PSU. I used to repair a TON of PC's that blew PSU's at the one place I worked, and that was always how they would act.


My last PSU served me well up till I installed 1 additional fan then went BOOM. I ended up throwing a 650 watt supply in so I'd not have to worry about blowing a PSU when I added anything else

For the record when I blew it I was running a dual core AMD, 9 Hard drives, a DVD burner, 9 case fans, forgot the gfx card((but it pulled a lot) looking back I'm shocked the 450W PSU I had lasted me as long as it did(ran over 2 years). Oddly when I threw in a 500 watt it blew after an hours so I returned it as defective, and got my current 650W in its stead.

DarkFire989

I got it in December. LB might be right and it could have been a power surge. My fault for not running a surge protector.

Lunchboxer

Spend $180 to protect a $3,000 computer, yo! Makes sense to me...

DarkFire989

No where close to 3000 man. Well under 2000 still.

Lunchboxer

With the rate that you add graphic card to it, it will be over $3k soon anyway...

DarkFire989

I have very bad luck with computers and RC cars.

Lunchboxer

Jumping RC cars 30' in the air and something break when landed is not bad luck.. it is just physics..

Just messing around, yo... good luck finding out what's the issue... !

One time when I plugged in an old PC and didn't know the power was switched on and same pop and smoke. Not good. My current PC is an Asus G72GX.. good computer but has the heat issues, white screen, flicker.. etc.. luckily gaming is a waste of time anyway but it would be nice to be able to use the hundreds I've spent on games..

Foxy

BSODs are just the way windows translates certain fatal errors, they are not related to any specific hardware failures, although a memory failure when populated with data will ALWAYS cause a blue screen, there are many other situations which wouldn't (necessarily).

I agree it's probably a blown cap. Which is worse than it sounds, as that cap may be responsible for buffering power spikes to critical motherboard components. Get er fixed quick, and avoid using it until you've found out what the problem is.

TDN, gaming is a waste of time!??!?! What??!? What is this sacrilege! You're BANNED!!




lol, j/k.

DarkFire989

Yup calling corsair today. Too impatient for the RMA process to be done so while that's going on Im gona get another one off of Newegg.

Probably a Cap in the PSU most likely, or video card. The caps are generally used in th the "filtering" aspect in converting AC to DC. The affect may not be noticeable, except for some pulsating DC as opposed to straight DC. A good visual of the Mobo, Video Card and PSU circuitry may reveal something...
