Need Help, Missing Bios Screen

Hi all, I'm in need of some help or ideas on what I can do.

My system:- Bought at Overclockers May 09.
Ultima Eliminator OC Intel Core i7 920 2.66GHz @ 4.00GHz
GTX 295 1792Mb DDR3, 12GB RAM, Motherboard GA-EX58-UD5, Win 7 Ultimate 64Bit

Problem:-

A few days ago I had a couple of screen freezes with the GTX 295 so updated the drivers to the latest drivers 266 I think. As I use a Sony Bravia 37" as a monitor I can't see any boot up screens until windows loads. Last night I had a screen freeze and decided to re-boot but the system didn't complete the operation. As it was getting late I knocked it off to do later.

Today I plugged in a Philips 19" to observe the boot up, at first the initial screen had dashed lines but as the BIOS screen kicked in it was a mass of symbols and totally unreadable, it would get to window loading screen and then stop and hang. (corrupted BIOS)
I re-booted the system and it got worse as now there is no BIOS screen at all. :confused:

On POST there are no beeps to indicate anything is wrong so I am assuming the CPU, RAM and video card are working as they should be but can't be sure. Motherboard GA-EX58-UD5 has a 26 showing in lights.
From manual
26h 1. If Early_Init_Onboard_Generator is not defined Onboard clock generator initialization. Disable respective clock resource to empty PCI & DIMM slots
2. Init onboard PWM
3. Init onboard H/W monitor devices.

After asking support via OC website, they said take CMOS battery out as below

I took the CMOS battery out of the machine for 15 mins (cables disconnected etc) as instructed but alas to no avail.

I can't see the BIOS to change to onboard, I can't flash the BIOS as I can't access the BIOS screen (F8 QFlash).
There are no burn marks, smell to suggest faulty boards/frying etc, all fans whirl away as normal.

Graphic card, I can't tell if it is working as there is nothing on screen and haven't a spare machine to put it into to test. All cables fitted and secure.

I thought I would ask here to see if anybody had any ideas, I am a qualified CompTIA A+ but I'm obviously having a brain fart/bad day as my logic gives me only two routes.
Graphics card or Motherboard, but I could buy one and it could be the other or none at all and just wasting money.

To be honest I'm stumped and at a loss, hopefully some kind person out there will help out and provide an answer. Hopefully I have given enough infomation for you to get the picture.

Thanks in advance

Do you mean you don't see the "Press delete to enter setup" message.

If so, you could try restarting the computer and keep tapping the Delete button as soon as the computer starts.
 
You took the cmos battery out. Now, I'm not familiar with your motherboard but usually one has to remove battery AND move a link in order to reset cmos. Then leave it for a few minutes. In theory 5 minutes should be enough but in practice I've known it take up to 30 minutes depending on the motherboard.
 
I had the exact same problem. It was the PSU that had gone and taken out a couple of ram slots

Ah thanks for replying, can you be more specific reference PSU.
How did you recognise that was the fault? Mine seems ok but I will need to have another look.
Possibly a new motherboard to boot :( and check condition of RAM/CPU

Sorry for the questions, gathering as much infomation as possible, but very helpful, thanks.

regards
 
I did try my PSU in a mates PC and it worked but after trying it again in mine still no post. So I used another PSU I had just to power the ATX connector and my faulty PSU to power the GPU/CPU etc and it booted up fine. So PSU wasnt supplying my MOBO with enough juice
