Help! Whats wrong with my pc?


Recommended Posts

The other night I sat down to my pc for a night of MOHAA, but discovered my pc won't boot up. I turn it on and it gets as far as two leds on the mobo and stops, blank screen and all, but hdd's are spinning away. After 5 hours on testing, resetting cmos, testing resetting cmos again and so forth I have now come to a grinding halt! I'm out of idea's. This is what I found in my testing:

1 both gfx cards in, pc won't boot.

2 take the lwr gfx card out, leave top one in, pc won't boot

3 take the top card out, leave lwr one in, pc won't boot

4 switch card around, pc won't boot

5 put lwr card into top slot, pc won't boot

6 put top card in lwr slot, PC BOOTS!

WTF!

lwr card doesen't work at all but top card only works in the lwr slot! Man I'm confused.

I have also switch the ram around, ptu one in at a time, used different ram altogether aswell.

I thought first maybe the bios is screwed and I need a new chip but I haven't flashed the bios at all since building the pc, it had the original bios on it.

 

Any other suggestions. :confused:

Can I assume there is no leak at all? You mighjt need to try to boot the system out of the case. It sounds like something might not be seating correctly or there might be a short of some kind or loos connection.

 

Dude I've tried everthing excapt for pulling it right out of the case. I can't see how that will help coz it worked one night and the next it didn't without even touching it.

 

Btw it wasn't overclocked at the time of death.

Hello,

 

What BIOS are you using?

Original BIOS = 310 or 125.

 

Both are not recommended for your CPU and modules.

Try BIOS 510-2FIX.

Well I'm not sure coz it's the original one on the mobo, I have never flashed it before coz I'm not sure how too so i left that alone. But someone said to me it might be 125 as thats what came with the boards, or used too.

Just replace the BIOS name with the one you use.

 

Use BIOS 510-2FIX.

Sharp, your help is awesome and much appreciated, but I think you should point out to people that the 510-2 FIX (or any other BIOS besides the official 125, 310 and 623-3) are beta, and usage of these BIOS'es will void your warranty.

 

Nonetheless, the tip you gave is still good, because 510 seems stable by many users. So, no offence ;)

thanks for the reply guys but I can't even get into the bios to do anything atm. Well yesterday I gave up and sent it to the place I bought all my parts from and he will have a look at it for me. I don't think he's to happy though, I bought all my parts from him and the psu and one of the hhd's were faulty before I even got it booted up for the first time.

I hope its only something like the bios chip is screwed and needs to be changed and hot flashed or something, for his sanity too!

 

If anyone has anymore ideas please feel free to throw them my way.
