Pc fails to boot

BringTheRain · 15 Sep 2011 at 16:48

Problem seems to be getting worse.

Had this problem once two weeks ago, and then twice last week. Now about 4 times so far this week.

Sometimes when i power on the machine, it wont post and just keeps restarting.

Once it just hung and failed to boot.

Never get anything on the screen.

It usually restarts after about 3/4 seconds. Sometimes it will get to windows after restarting 3 or 4 times. But once it refused to boot.

So far I have

Removed overclock.
Reset CMOS.
Checked connections inside.

I haven't got a pc speaker installed, would be an advantage to get one installed. The next time it happens, hopefully I would get some bios beeps.

So guys, what to check now?

Thanks

Havent got the gts 250 flogged it.

Will try the ram thing, but it only happens every now and then grrrrrr

Never installed the 6990, as no point, as knew psu wouldn't handle it.

Will have a think on the psu, if not will just sell it as it is.

I would lend you one of my motherboards but dont fancy posting them or wanting them killed

ROFL - Bad idea

I am thinking about taking it to a local pc shop.

I am just too busy,

Got a mountain of parts sitting in my room for this build as well lol!

I am tempted to think the psu or mobo. But the thing is, with this sort of ****ing problem it could be anything FFS!

EDIT - Hmmmmmm

is Internal PLL overvoltage Enabled?

Get the latest BIOS, and if it is enabled, disable it, i was having this problem on my sabertooth and had this enabled when i didnt need to. I disabled it and it solved my problem of the cold boot on off on off on thing.

Well mine was enabled, so have disabled it

BringTheRain · 15 Sep 2011 at 17:52

I havent really done any testing other that what i did in OP.

Will give memtest a bash then as well.

Thinking of getting a new psu anyway, i need something easier to sleeve

Good thinking batman.

Will re seat everything and have a nose.

But it only seems to be from cold boot.

So will have to keep switching on and off over the next week or so.

Thanks guys. Helpful as ever

Yeah had a look at it. Not going for red and black though

Got my parts from Germany though (silverstone)

OMG they were quick, expensive. But quick.

Ordered a few more bits for the case.

So should be able to start my build log properly soon

Even got a nice camera, instead of iphone 4

Nah, just asked my dad for his nikon 12 mega pixel jobby lol.

He dont use it any more

Cold booted today and no issues.

Bit on reading up on another forum.

It seems to be quite common on asus boards.

Searched online and it happens to quite a few people.

So not bothered now

Seems to be sorted with the advice given on another forum.

Just did the PPL thing.

Tested about 50 times on and off over the last 36 hrs and it is GOLDEN

Seems to be asus boards do it :confused:

But they call it a double boot ?

Ah well all good, thanks for the advice/help.
