Boot up issue

[Z4 Animal]

Ive started to have start up problems with my pc.

Bought the Sabertooth X58 board less than a year ago with I7 cpu and memory.

Problem is when i press the start button on the tower the fans start,HD light comes on and LED's but like in half power.

Repeatedly resetting or removing power cable or flicking PSU on and off gets it past the first stage and then posts.

After that pc is perfect no issues at all.

Failing PSU or faulty board? I have downloaded the latest bios and it's not overclocked.

PSU 1000w bought 3 years ago from PC World.

That makes it sound like the PSU to me.

Yep, sounds like PSU.

one thing to try is to remove all "mormal" cables off the motherboard, pci cards, cmos battery, memory , power cables, disk drive cable, Then plug in motherboard power and power on (probably wont go), check any beeps with manual
Put new CMOS battery in and power up (probably wont go), check any beeps with manual
Put in memory and power up. At this point you should be able to power up reliably into the BIOS setup

If you can't, then it is the PSU

I have just spent the last few weeks fixing/prepping about 300 used PCs and have had a high success rate with this process from Acers to HP to IBM PCs that wont boot or wont boot reliably. 98% megatrends BIOS crap

sometimes (acers esp) a dead CMOS battey will cause boot problems or not boot at all due to flat battery

Agree with the above posters, PSU on its way out.
