Slow PC boot - A2 error

[uher.dom]

When I start PC, It sounds like it wants to boot normally than it is silent for some time and than black screen appear with error code A2 in right bottom corner. After approximately 5 minutes it launches Bios and windows normally. In windows, everything runs normally. It starts doing this slow boot two weeks ago.
I reinstall windows didn´t help
Reset BIOS settings to default didn´t help
Checked all SATA cables didn´t help

When I disconnect Pc from electricity for some time and than put it back for the first time it launches normally but next start is slow again.

Don´t know what to do. Any idea?

A2 is for harddrives, if it stays for too long on this post code, one (or both) of your harddrives starting to have issues and that drive will die soon
u do have only 2 drives, so u just unplug sata cable (small one) from one drive than do same with the other to find that bad drive

If it is what this guy says then I would download and install - Hard Disk Sentinel this very second and see what state the hard disks are in. Plus I would always recommend this software just because it has saved me and warned me about failing HD's.

Sentinel says my first HDD has only 7% health. So it might be the problem will check if disconnect help.

then use is maker software to test it you might need to get a new one .

7% is on deaths door - get your important information off of that ASAP
Either to USB, HDD or Cloud!

It could also be loose cable. In smart in the disk it should be mentioned as many records in interface errors or something like this.
If you can, you might as well show us smart on this wrong drive. But as people mentioned before - back up the stuff as quick as possible. Best - without power off the pc and disk, it might be dead next time.

So I wait some time for HDD to crash. But the health rise up to 70% (HD sentinel software). Anyway i bought new SSD disk to replace it. But even in clean instalation on SDD when only SSD was connected tha A2 error was still there on every boot. So i gues HDD wasn´t causing the problem. Any other suggestions? Thanks

Did you remove ALL old hard disks, before installing the new one?
Also did you use a new or old cable?
If you are installing windows from new, you should only put the hard drive in you want to install windows onto and disconnect all the others.
A2 is an initialisation issue of Hard Drives.

a2 itself isnt issue, its just post code telling you what your PC currently does, if PC sits still too long on this post code than it waiting for all ide/sata devices to get initialized before it moves to another post code

disconnect all sata/ide cables, start pc and see if that a2 still sits for too long

Yes during instalation only new SSD was connected. I tried remove all HDD and SATA again and connnec new SATA cable to SSD. System boots fast now but A2 code is still on the screen but only for a second. Than i start to add Second HDD with diferent SATA cables works good with all. Than I add last problematic HDD, boot was still fast but Windows didn´t launch. So i removed last HDD and repaired Windows. Now it boots fast with A2 code. What do you think about this? Is the Last HDD causing this? For me it is like magic i just unplug all and put it back one by one and it works. wierd?

So the code is just it telling you "what its doing now", so when my mobo turns on, a whole range of codes are shown as it goes through the loading sequence, and when it gets to A2, for me takes about 2-3 seconds because I think its my 9 Hard Drives in my machine.
When I have had a problem before, it sits on A2 for a long time like you said, which means it normally is a failing HDD.
Can you put the Last HDD in and the new SSD?
If you can, then try Hard Disk Sentinel to see how bad that HDD is, if it cannot boot up, then yes, that last HDD is dying/dead.

all seems to be fine now, once slow a2 reappers, u will now know what to do
