Incredibly slow post boot with GPU fitted

Someone must know the answer to this

One day i moved the case slightly and the machine wouldn't boot...red mem light on.

Eventually after a lot of messing about i found that the psu was dead , 1 stick of ram dead and the cpu gone.

Time To upgrade , i got a new Asus p8z77-ws Booard , 32GB Ram and a 3770k CPU and a Corsair Rm 850 PSU,

loaded it all into the Silverstone case and after leak testing fired it all up.

One thing i noticed straight away was that the thing was sluggish , it took a long time to boot , you had to mess about restarting it but eventually it fired up , water temps were always acceptable ,but something wasn't right.

In the end i took it all apart and cleaned up the gpu, the 590 was almost 4 yeas old and i noticed some of the pads had melted and crublemd so i took it all aprt and cleaned it all up.

While all this was happening i found a cheap Corsair 900D on Ebay so snapped it up.

Rebuilt the machine back into the new case, added in 2 extra radiators as there was room to handle it.
Added in a lamptron Fan Controller to power the fans

Fired it up and got the no VGA Beeps , nothing i could do would fix it , so i threw in the towel and bought a brand new GTX 980ti from Overclockers (block fitted as supplied)

Fitted the card , fired up...Bios still very slow , gets stuck on the q-code B2 for a long time , it will boot eventually but you have time to RTFM a few times whilst it does but it is still sluggish

the motherboard has on board gpu so i unbolted the gpu , pulled it out slightly so it wasn't connected , removed the power from the Card and fired up the system....

It shot throught the post , and booted withing a few seconds.

I card was brand new and i don't think both cards would be out so i'm looking at the PSU either being faulty or just not up to the job

System specs

Case Corsair 900D
MB P8Z77-WS (Latest Bios v 3505)
CPU I7-3770K
GFX Nvidia GTX 980 TI
1 Bluray Drive
1 Samsung SSD
2 x 4TB Seagates HD
1 x front sata drive caddy (2.5 / 3.5)
1 x lamptron Fan Controller
1 x 480 (4 x 120 fans)
1 x 240 (2 x 120 fans)
1 x 480 (8 x 120 fans 4 pull , 4 push)
1 x 140 Fan (Exhaust)
2 x 120 (front pull)

Yeah it is probably fan overkill but i consider myself slightly Autistic and if i have a slot free i need to fill it

all this is powered by a Corsair RM850

Question is is it up to the job?

***UPDATE****

I disconnected all the fans and HD's etc except the SSD.....Same Thing

I pulled out the 980 and replaced it with a passive cooled brand new 210. Same thing. Post is VERY slow.

I put the 210 in the 2nd x16 slot....Same thing. Post is VERY slow.

I've removed the cpu and checked for bent pins , can't see any bent pins.
 
When the bios is slow like that its very often a motherboard issue. I had the same problem before the motherboard eventually died.
The irritating thing about them is the problems can be intermittent or just slowly get worse. I recommend getting another motherboard to test if you can get hold of one.
 
Disable legacy usb support in your bios. Happened to me when I switched to team green last week, haven't got a clue why but changing that seems to fix it for most people!
 
Wow you has 17 fans, far too much fans. :eek:

Accorded to ASUS P8Z77-WS manual, Q-code B2 mean Legacy Option ROM Initialization.

So you will need to disabled Legacy Option ROM if you don't used RAID.

have you reset the bios and told it to boot from gpu to see if its still slow to boot to windows,

have you removed the old drivers, if so you may need to do a clean install of windows

I have done , although this was done whilst the GPU was fitted , no change.

As this is a low level POST issue Installing Windows or drivers will have no affect

As others said in your other thread, turn off legacy BIOS features

At 5.35 am , after a sleepless night , a lot of coffee and swearing , Post boot is behaving normally with a GPU fitted into the first PCI-E slot.

Currently using the 210 as it is easier to swap in and out. as it had the same symptoms i'm reasonably confident the 980 will work.

I removed the GPU and booted into Bios setup using the internal IGPU , couldn't find any option to turn off Legacy rom stuff

so...

Turned off Legacy USB....didnt work
Turned off EVERYTHING in the bios that had a disable option....didn't work

tried a sound card in each of the pci-e slots , too see if the ports were dead....didn't work

Removed the ram and tried one stick at a time....didn't work.

I noticed on the board has 2 switches EPU & TPU which are disabled by default

I turned on the EPU one and got a nice little green light.....didn't work

i turned on the TPU one and got a nice little green light and a nice normal fast post boot :)

not sure exactly why enabling the TPU one effects this but looks like it is working normally.

This is what the manual says about TPU & EPU

TPU
Unleash your performance with ASUS’ simple onboard switch or AI Suite II utility. The TPU
chip offers precise voltage control and advanced monitoring through Auto Tuning and TurboV
functions. Auto tuning offers a user friendly way to automatically optimize the system for fast,
yet stable clock speeds, while TurboV enables unlimited freedom to adjust CPU frequencies
and ratios for optimized performance in diverse situations.
EPU
Tap into the world’s first real-time PC power saving chip through a simple onboard switch or
AI Suite II utility. Get total system-wide energy optimization by automatically detecting current
PC loadings and intelligently moderating power consumption. This also reduces fan noise
and extends component longevity.

Thanks for everyone who helped :)
 
If it's any help my system booted fine till yesterday. Now it takes 30s longer. Something must have updated in win 10 which is causing it
