Upgraded CPU & mobo....no POST, fans, beeps, lights...NOTHING!!!

[JLiRD808]

Pulled the RAM and HD's so as just to narrow it down to PSU, mobo, CPU, and CPU fan.

Push the power button and NOTHING happens (even tried bridging the "power on" heads with a screwdriver). We thought we grabbed a bad mobo [ASRock z77 Pro4 1115] so I just swapped that out. Same problem!!

So maybe the CPU? Its an i5 3570k Ivy. Perfectly compatible with a z77 1115 correct? Almost impossible to seat a CPU wrong IMO- the notches lined up, clamped the cover down, Hyper 212 mounted correctly as far as I can tell (done it like 10x before)

Tried two different PSU's, one was BRAND NEW out of the box. Though, I found at a lil after we ruled that out that it was a bit of an older PSU. It also only had a 4-pin atx12v and the mobo has an 8-pin. The ASRock manual clearly states that a 4-pin should be ok though.

Standoffs in place, and no extra standoffs anywhere. CPU fan is plugged into CPU_fan1 on mobo. Tried the brand new stock fan too...NOTHING 😡

Cant think of anything else.....reinserted the mobo battery, reseated CMOS jumpers.

Anything I forgot??

THANKS!!

Ram model? have you confirmed with Asrock's website that it's compatible with your board? and yes ram model compatibility can be vital.

HA! Ok....so yes, the ram is NOT compatible. I can get that resolved tomorrow.

However, with no ram installed, shouldn't it still power up until I get the 3 beep codes for "no memory found" or something? I thought it at least tries to make it to POST without any ram installed.

Do some mobo's not even power up at all if there is no ram installed?

THANKS!!

users have reported the mobo lighting up at the very least. otherwise, you've already went through 2 PSU's/mobos, so either whoever you're buying from has a stockpile of bad batches or you just have plain sh***y luck to have grabbed 2 bad batches of either (or both) in a row.

no offence, but it's better to be sure and it has happened before; have you plugged in the 24-pin power connector to the board? maybe try plugging in an 8pin EPS despite the 4-pin compatibility?

eitherway, the RAM's a new start, i guess, and hopefully, a solution. good luck.

Yeah I plugged in the 24-pin....just ran this test though:

...and my PSU's NOT starting up. I dont have access to my friend's PSU anymore so I cant test his. Crazy that his brand new one out of the box would be DOA, but I now CANT rule out mine (unless I did the test wrong lol).

Gonna head to MC tomorrow and I think they'll do some POST tests for $20. I can try their PSU, and rule out whatever seems to be the issue.

Thanks for the help!
