Pc wont boot

sjcf1 · 18 Dec 2011 at 01:51

Just tried putting in a new modular power supply into my pc, and the thing wont boot up. No post nothing. Specs on the thing are. I7 920, asus p6t. 6gb ram. Xfx 5850 with 3 1tb hdds.

Old psu was a 600w tagan, and the new one is an ocz modxstreme 700w one. Ive tried putting the 5850 in it, a 5770 in it, and a x550 in it, and only the x550 works after a cmos reset.

Any idea why the other 2 cards arnt working?

The modxstreme is about 2 weeks old and it came out of a cheap uni build after the psu in that failed, but the ocz psu has worked and did do up until today with my uni build (q6600,4gb ram and a 5770).

Any ideas why the thing wont work now?

Thanks in advance

Check that the modular cables are pushed right into the psu.. Afew people have commented on the connections recently.. Is there power to the board at all.??

Just tried it with a different powersupply an the 5850 in it, and it still wont boot, so im thinking that the gfx card has gone

. Im using a powercable that came from one of my monitors, it power a test pc that is next to it atm. And the cable works the rest of the board gets power. So unless theres any other suggestions i think its the graphics that have failed probably.

Does mobo have multiple pic slots you can try!??? Failing hat try he card in another pc or another gfx in yours if you can..

Update stripped the thing down to bare mininimum, and it makes 1 beep and then 3 short beeps, this ive looked is a motherboard timing issue or faulty board.

Tried the card in a differnent pci slot and that doesnt make a difference, ill take apart another pc that should be able to power the pc in a mo

Tried the GFX in another machine, and the card doesn't work in that, so I'll have to RMA that. Tried building my main machine with a spare 5770 that i have and it decides to restart multiple times before posting, and now its not posting... great.

Ouch not having much luck.. Anyone else with Any suggestions??

Another update, i've put all the working stuff together with the P6t and its now taking four restarts to successfully post. I've tried it with different memory, and contacted the reseller who suggest its a motherboard fault - so thats going back today.

The card on the other hand is deffinatly faulty so I'm currently arguing with XFX and a competitor about who I have to send it back to - there both helpfully telling me the other party has to take it back.

Thanks for everyones contribution to this.
