PC not booting

4737Joker · 13 Aug 2008 at 20:02

Hi all,

woke up this morning and turned the PC on, nothing happened, just a black screen and the monitor doesn't come on. All the fans come on and the lights but no screen.
The PC isn't booting into windows I don't think, when I press some of the buttons on the keyboard the lights on the keyboard flash then nothing; capslock key doesn't make the light go on/off etc.

I've tried the following: -

Took the RAM out, tried RAM in each slot and in different combinations.

Took out the graphics card and reseated it several times.

Took out the Motherboard and rebuilt it all from scratch.

When the PC turns on the Graphics Card fan seems to go to full speed instead of settling down. The monitor light just stays at orange. There's no beeps or anything, the only thing odd is the graphics card fan going to full speed.

The system is as follows;

Abit IP35 Motherboard
OCZ 2x1GB PC2-8500 1066mhz
Intel Core 2 Duo E6550
BFG GeForce 8800 GTS 320MB

Anyone have any idea's?

Thanks!

Yeah I've just reset the CMOS. Also forgot to add I've tried booting without any RAM and the exact same thing happens.

Ok I tried his Graphics Card in my PC and the same thing happened so I think thats ruled out. Any more ideas guys?

If thats the case its fairly disappointing as its less than a year old. Any idea if it will be covered by warranty?

By everything I'm assuming leave RAM/CPU in?

Ok, tried a spare PSU and it does exactly the same. Also I get no beeps at all unless I remove the power cable from the graphics card.

Yeah the motherboard has onboard speakers as it beeps when I take the power cable out of the graphics card. I've just tried resitting the processor and basically rebuilt it from scratch and got exactly the same thing.

Think I'm gonna have to try my processor in my friends PC and see if its that.

Yeah I did try without the RAM and got nothing, no beeps or anything just the same.

Ok, tried the CPU in my mates PC and it worked fine. Tried the RAM and it just beeps for a long time, I think that might just be a compatibility issue though because 2 sticks of RAM are hardly likely to stop working at the same time.

I'm guessing this is gonna be a Motherboard issue but I'll take the RAM and Graphics card to my other friends house and double check. If they both work fine its probably gonna be the motherboard and I'll be looking to purchase a new one I guess!

Tried the mobo outside the case on some antistatic surface? Might be shorting it somewhere...

Yeah I took the motherboard out of the case and reseated it all and got the same problem.
