Error codes A2 B4 98

Hi Makskomp, welcome to the forums.

First up, it is perfectly normal for all boards to cycle through codes on the
debug display during POST. Power On Self Tests, the codes each correspond to a
test in that process. Once all tests have passed the system will begin to boot.
So when a test fails and the system halts, the code displayed gives you an idea
of what test failed, you can look up the code and see what it pertains to. In
other words, the only codes you need to worry about are ones that do not change
and remain, typically with the system unresponsive.

As for the slow POST process, disconnect everything from the system except for
Keyboard, display and mouse. Quite often a flash drive or conflicting USB device
can cause slow POST times.

If you are getting a code, it will be the last one that remains on the display,
that is the only one we need to look into.
