Strange BIOS / No input signal problem...

[jimbobsimmonds]

Hi all.

I am literally at my wits end trying everything with this PC, asking everyone and 8 weeks later no luck...

basically, i have a computer that, for some reason will boot some of the time and other times just will not. Resetting the CMOS seems to help but not everytime...

All i get is "no input signal" and it doesn't even go to BIOS...

here is what i have tried...

Another mobo
another G-Card
Removing reset button
new monitor/cables
new PSU
turning to jesus

none of the above have worked...

really on my last straw and considering selling for bits...

cheers
jimbob

well before the mobo was a Foxconn 975X7AB-8EKRS2H with 2 sticks of Samsung DDR1 1Gb RAM. and an intel 2.66GHz quadcore processor and 2 crossfired ati radeon x1950XTX... also has 2 hotswappable 500Gb HDDs (sorry cannot be more precise, will check hardware next time it starts)

I bought an 850W PSU, new P5KC mobo, 4Gb new RAM (compliment the 2 in there) and a new ATi radeon 4870 g card. , DVD R/W and a decent used case.

yes, 8 weeks and a lot of money and swearing i still can't get it going consistently...

its DDR2 RAM but there are DDR3 slots in my mobo...

looks like im going to be snowbound tomorrow so will definitely give it a try out of the board...

what's your hunch atm?

 

[jimbobsimmonds]

and yea, that's the mobo!

how do you think the CPU could cause the problem and tbh i do not know what it is. Just its an Intel Quad Core 2.66GHz...

it is pretty much the one thing that has remained untouched...

doesn't beep even when it starts good

and i dont know about the thermal paste as a mate did it but it seems unlikely the same fault would occur on 2 mobos... CPU looking like a prime candidate now...

right, tried taking all the RAM/HDD/DVD out... no joy...

next potential solution please snowed in today...
