Freeze on motherboard splash screen.

[Kronos]

Last thursday I booted up my PC and before I was fully booted I received a black screen with 'Parity Error' in top left hand corner and nothing else. Not the first time I will admit as I happened a week ago. Did a bit of Googling and it was suggested that it maybe a RAM issue so downloaded and ran Memtest 86 but no errors reported.
Had a look in the BIOS and the timings were all wromg and I have no idea why. Whether resetting these cures my issue only time will tell.

The following morning, yesterday, I powered on my PC to find it would go no further than the splash screen, beep once so I assumed all was well but obviously not.

Okay so I must have buggerd up the settings so simplest thing to do would be to go into the BIOS and set to default, except I could not as my hitting the delete key on the mech KB had no effect, Decided to try a bog standard keyboard in a front USB and I managed to get into the BIOS reset it and booted as normal, problem solved.

Except it was not, this morning same thing again, same process of connecting the other KB went into BIOS, did nothing but exit and booted as normal.

Googling this issue I have come across it being a USB issue and with the KB connected to the rear this might in fact be the case thoough I am not convinced.

I might try reinstalling mobo drivers in case it is an issue but anything else I should look at?

BIOS battery, BIOS update, reinstall.

I would try clearing the CMOS by taking the battery out for 5+ minutes, maybe remove anything unnecessary from the mobo such as usbs, sound cards etc. If this still fails remove all but 1 RAM stick and repeat.

Be sure that the CMOS really was cleared by seeing the default splash image or whatever your mobo does.

If you have access to a BIOS file I would probably flash the mobo the first chance you get.

Depending on your mobo it might have a dual BIOS which can be activated by turning your PC off, holding the power button until it turns on and off again. Press it a 2nd time and it should hopefully try and boot from it.

I had some boot issues quite recently and this is how I finally got it sorted.
Beast of luck.

Should have mentioned guys that I did indeed remove and change the battery, and cleared the BIOS yesterday so when it happened again this morning it came as a bit of a shock.

Will see if there is a BIOs update but I am sure mine is up to date.
