Help : Dads PC not displaying? Opinions?

Sime · 28 Dec 2008 at 15:36

Hey everyone, for xmas I bought my dad a new CPU, GPU, RAM and mobo.

Swapped everything over, booted it up but nothing is displaying on the screen at all...Not even the light it powering up.

The actual tower SEEMS to be alive and well (not rebooting or anything) so im pretty confused...

I thought it could be the graphics card (8800GTS 512) but i had the in my PC like 10 mins ago and it was fine.

What would make my dads pc not display AT ALL? (no monitor activity)

System Specs

6550
DS3
8800GTS 512mb
400W PSU
2x2gb 6400 ram

Help?

By no light do you mean on the pc case or the monitor?
if monitor recheck cables/fuses
Is there on board gfx and gfx card?plugged into correct one?

on the montior. All the fans and light seem to be fine on the case. Wired thing is, the montior is fine becuase im useing it as we speak but just with my bros PC.

if monitor recheck cables/fuses

As said above, everythings working with my bros PC.

Is there on board gfx and gfx card?plugged into correct one?

Nah i dont think theres any onboard video on a DS3. Yes plugged into the correct one

check all power cables are connectedinside case?check psu power cable outside case and fuse?

Like i said, if it was the PSU, would all the fans and lights boot up aswell? Wouldnt it just be dead?

Few suggestions

Poor dad

He was looknig forward to some new PC stuff aswell

I had this and remounted the CPU and it got it going... just an idea

ANDARIAL · 28 Dec 2008 at 17:09

maybe try safe mode,to see if the res or synch has been set too high/low?
Can you try another monitor on the pc?
Just reread your original post,you mean that you changed the cpu.mobo and gfx and ram and just put the old hdd back in WITHOUT reinstalling windows?

Might be the psu, 400w ain't a lot for that hardware.

The single most common cause for a system 'starting' ie fans spinning, but no video is the 4/8pin 'Intel' connector isn't plugged in.

Is that definitely plugged in?

Check all connections again and maybe reseat everything.

If it's still not working and all the connections are correct then I'd suspect either the PSU or motherboard.

What brand PSU is it?

He is right. Mate had this exact problem the other week, make sure there plugged in.
