I need some help with a strange PC problem

[CoryAlan]

I bought an old Radeon HD 6850 off a friend for $50. Now I like this card, It matched well with my Sandy Bridge i5 based system, Now I decided to take my gpu into where I've been doing work experience for the past 4 months. It's a small computer refurb company. I cleaned my card with a few quick bursts from an air compressor. 

 

But for some reason when I plugged it back into my PC, it wouldn't display anything, but power was running through it. A friend of mine there said that it could be the refresh rate on these old monitors and that it should work when I get home. The 6850 had the same problem when I tried it at home. Now i CAN'T even use my PC since the motherboard won't display anything either. I've tried both VGA and DVI. So I'm assuming my motherboard crapped out on me.

 

Sorry for the long message, but I need help.

Its not a long message, but you might have broken something with that air compressor depending on how strong it was :L

[CoryAlan]

That might be true, but my mobo won't display anything. And it doesn't make the start up beep noise anymore.

try to see if the PSU is working

 

then with only the CPU and RAM installed

 

and using onboard display connect to monitor

 

and try to boot to BIOS

So its not posting.

Have you tried the usually tests removing your ram ect.

I have a 610 watt Gigabyte PSU(which I don't trust all that much). The PSU is working fine, when I turn on my system all the fans are running, even my GPU fans. But the mother board doesn't do the 4 beeps it normally does. Hence why It's a strange problem for me.

try with only 1 stick of RAM in first slot

 

if there is no beep 

 

it means the mobo is truly dead

Its failing one of the tests what motherboard do you have?

 

Its normal for it give out when there isn't ram or sometimes a keyboard.

Sure sounds like you fucked it up ^^

My System parts are in my profile. I only have one stick of ram. First time I've encountered a problem like this. But then again I have only been working with PC's from as far back at 2004.

ouch looks like the mobo got shorted by something

 

time for a new board and CPU

 

the Pentium and Z97 combo might be a good option

[CoryAlan]

3 different computer stores(2 near me, 1 in another state) still sell 1155 motherboards. I like my little sandy bridge i5. It's a workhorse ahah. But I do believe the mobo has been shorted in some way. I'll be my comp in next time I have work exp, and run all the tests from that thread. Thanks for the help guys.

Got it working guys, turns out my power supply is a tad dodgy

What's the rating of it? Probably can't handle the GPU.
