computer POST problem

[bluemoon_19]

Hi guys I have been having trouble with my pc and its slowly gotten worse to were I can hardly get my pc going. The problem is it wont POST without repeatedly hitting the reset button or powering off and on.
Once I get it going it works perfectly boots to windows in less than a minute and works fine for hours. I have had it for 1 year and it hasn't had even 1 BSOD so I'm pretty sure the hardware is good.

I recently found giving the case a bang on the top helps so I thought mabye the power button was the problem. Today I turned it on manually from mobo and it still didn't POST. Do any of you guys have any ideas?

Did you try unplugging and plugging it back in again?

There's little I can actually suggest without a little bit more information, but clearing the CMOS and going from there would be a fine start.

Ok thanks will try when I get back home. Oh also just remembered I updated the BIOS to the latest version

OK back home now I cleared CMOS and still no luck need a few bangs on top to get it going. I did take it to my local computer shop twice and both times it worked fine for him. He reseated everything and when I got it home it worked ok for 2 days before it started again. It seems like the car journey must have shaken the thing into working.

specs of the machine as follows.

CPU: AMD FX-6300
GPU: Sapphire R9 270X
PSU: Corsair CX 600
Mobo: Asus M5 A97 R2.0
SSD: Kingston V300 (120 GB)
HDD: WD 1TB black

Are all of the power connections secure?

After doing a bit of research it would appear your board is a little fussy when it comes to booting, you can try what's suggested in this post on Tom's Hardware:

I called ASUS tech support directly with this issue and this is what they had me do:

In BIOS go to AI Tweaker and scroll down to change boot options on your hard drive from "Legacy opROM" to "Both, UEFI first" to fix boot issues. It defaults to Legacy opROM and most hard drives are UEFI now.

Also in AI Tweaker change the ram settings from "Auto" to "D.O.C.P." and then select the proper profile (profile #0) for your xmp settings. If your RAM is rated above 1333Mhz, you'll have to do this so the bios will load the proper speed for the ram. To see if your ram has xmp settings, in the bios hit F3 and select S.P.D to check out all your ram specs.

I had the same issue where the computer would not boot properly. I would either have to pull the ram out and reseat it every time, or power cycle 4-6 times before I could get into the bios and manually select to boot to my hard drive. I tried upgrading the BIOS, changing out the ram, changing the video card, changing the power supply, nothing helped. It was buried in the bios settings.

Thank you for helping but my BIOS looks different here are the pics (sorry for the huge size but photobucket was playing up and not loading editor to resize). I could only find the boot option you mentioned and that was under a different tab.

If I had enough money I would take a sledge hammer to this thing and buy something that worked.

And when you reboot using both legacy and UEFI, nothing changes?

Have you tried moving your 270 down (or up) a slot?

Seeing as you flashed the UEFI firmware, did you follow the instructions on resetting defaults after doing this?
Even though you flashed with new firmware, the CMOS chip which holds settings still has the older versions data.

I would back up your things straight away.
You could have a HDD issue where it will betected at times and then wont.

I would recommend installing a program called diskcheckup by passmark.
It will show SMART values for all hard drives

Yes the option to use both was already selected when I had a look. Sometimes when I do get the computer going it makes a different sounding beep and I briefly see an old American megatrends boot screen. the only thing of note I see is it says no keyboard found(could be because its USB?)

I will try moving the GPU later.

I think its OK as when I flashed it before it would boot it made me go back into the bios to put the info it needed back in.
I had some SMART programs on the PC and they said it was fine but I downloaded the program you said and got this. Not sure if its good or bad but the program says its fine.

I ordered a little board from Ebay that is supposed to display post error codes so hopefully that will be able to help. Only problem is its at least a week before it will be here.

But you need to reset the bios after the flash.
Just cause you had to readd the configuration doesn't mean much.
I learnt to reset defaults after any firmware flashing.

Ok I did clear the CMOS yesterday and I still have the problem. Or do I clear the BIOS another way? I don't know a lot about stuff like this.

You can do it one of three ways.

One is at the exit screen select the "set defaults or load failsafe settings" option then save and then configure the firmware.
The other way is to remove the CMOS battery and disconnect the power plug from the PSU and hold down the on button for 15seconds to drain the power from the caps, this method works the best IMO.

The last way is to use the CLRCMOS jumper and refer to the manual on how this should be done.

I would like to play a hunch. Can you provide more screenshots of your bios, in particular all of the options from the CSM? Feel free to PM to me in a zip file if it isn't too much worry.
