Hi any help would be mightly appreciated as I currently cant boot to windows.

I booted up the computer and it told me specifically this "AHCI BIOS NOT INSTALLED " and "CMOS CHECKSUM ERROR- DEFAULTS LOADED". So I went into the BIOS menu and reloaded the last good configuration which then, in turn, started the computer and managed to get all the way to desktop I do what I needed to for around 5mins (get word docs for the mrs) and then switched it off again making me believe all the problems were sorted. Switched it back on again an hour later and it comes up with the same problem, CMOS CHECKSUM FAILURE, so I loaded the last known good configuration expecting this to rectify it once again but unfortunatley after the reset it just held on the LAN Party JR X58 T2H6 screen (the mobo makers visual before loading the POST screen) and stayed there for around 40-50 seconds (Normally takes 1-2 secs) whilst I can hear the computer working away. It then loads up with a screen saying :

" PXE-E61 : Media test failure, check cable
PXE-MOF : Exiting PXE ROM.
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER"

After going into the BIOS Menu again and clicking "Standard CMOS features" I see that although my 300gb Baracudda drive is seen by the computer under heading "IDE Channel 3 Master" my SSD is nowhere to be seen (operating system is on SSD) yet they share the same ¨power cable so its definitley not the cable which I was told by the computer it might be + Ive already checked all that and its fine (Could it be my crappy PSU not providing enough power is what im wondering? Its been fine up until now and has run it for a week)

What I've done -

Reloaded CMOS to previous known working configuration - No change
Checked Standard CMOS Features for changes - SSD (OS) is not there yet other HDD is
Load Optimized Defaults - No Change
Checked physical connection between mobo and SSD - Absolutley fine

In all fairness I have no idea where to go next. Best I can hope for is to find an OS disc somewhere in my old place but its bloody miles away (I've just moved house) and even then I'm not sure how to get this SSD working.

If any computer whizzez / bright sparks out there could lend a hand I would be massivley grateful. I'm running Windows 64x Ultimate if that helps and my specs are :

i7 920

6gb Corsair Dominator

OCZ SSD 60gb

300gb Barracuda

DFI LanParty JR X58-T3H6 MicroATX LGA1366

Atrix Power 12v P4 Extreme Power 650W - (Will be changing tomorrow to Corsair Silver 750w)

Coolmaster v10

GTX 460 SE

Any more details that are needed please dont hesitate to ask and thanks again for your time it is very much appreciated

Have you tried a new CMOS battery?

Wrong section to put your question! damb it!
I am her to chill out and escape the PC talk... now you have ruined my relaxation :D 

Go into BIOS and find something along lines of perestrials or simular, set the controller to AHCI mode and save/reboot. If this fails set the controller to IDE and reboot.

If all fails it may well be a registry problem and you can then try setting the controller to AHCI mode in registry... just google it and its fairly simple(EDIT: noticed you can't get into windows, sorry)
Try changing Boot order in BIOS, change cables and sata power cables... disconnect everything no needed to boot i.e Opticle drives and usbs ect... thats what I would do...sorry I can be of more help!

Hi

There seems to be a misunderstanding of the PC startup procedure

'So I went into the BIOS menu and reloaded the last good configuration'


After the BIOS runs POST procedure it reads the master boot record of the boot device (hard disk or DVD)

Then Windows boot manager starts to load but if there are serious problems you get a message from Windows about 'Last known Good' 'Safe Mode' or 'Start Normally' (This is NOT a BIOS message)

You should not have needed to use 'Last known good' as this does not fix BIOS problems

as said previously you need to get into the BIOS

find option to Load cmos Default values , check that SATA Controller mode = AHCI for hard disk is on (if it was on previously)
(AHCI sometimes called Native mode. The opposite is ATA compatible)

check that date & time are correct as if the clock is scrambled Windows may have problems or fail to startup

check that boot order is correct if you have more than one hard disk.

usually the cmos button batteries last for many years so if this occurs again check the voltage of cmos battery
(usually lithium technology 3.0 Volts)

Are you overclocking the CPU or RAM etc in BIOS ?
as overclocking could cause crash with corrupt cmos settings as could hardware failure
(cmos = battery backed memory storing critical configuration information)
