New board, ram, PSU... No video input...
Posted: Sat Jan 31, 2009 5:05 pm
The other night after cleaning my PC, my PSU blew. Seriously, smoke came out of it, it stunk. I went out and bought a new PSU hoping it would fix the issue but sadly my MoBo and PSU were dead.
So, I go out and buy a new MoBo, a new PSU, new CPU and new RAM. But I keep getting "no video input" on my monitor. At first I thought it was a bad MoBo, but I've changed that for qa new one and the problem stays...
Some notes:
1) I've reset the cmos jumper, no change.
2) I've tried a clean boot with just whats needed, i.e. the mobo, ram and CPU/fan, no change. The new board has no onboard VGA, but still even with my GPU plugged in, no change. So the problem is there no matter what video input I use.
3) Checked, double checked and tripple checked wiring. All wires that would be needed to boot are in place.
4) Same issue on two mother boards now, not just one.
Now as I said, I've already took the MoBo back to get that replaced and that never fixed my issue. I'm now left thinking it could be the CPU (Not Likely) or the PSU (Possibly). Anybody else think the PSU is the case here?
When I flip the switch on my PSU, the machine comes on straight away. The CPU fan spins full speed constant, the GPU fan spins full speed constant. I get no error beeps at all, regardless, unless I leave the power cable out of my GPU, in which case of course I get beeps...
So I'm really at a loss here... I've stripped it down to its basic components, three of them, and its not the mother board so I'm now down to two... Could it REALLY be a faulty PSU I've got? Would it still power up as such, but not give video input? Any thoughts guys?
Specs:
AMD Athlon X2 Duel Core 5000
AM2 ASRock ALiveXFire-eSATA2
550w PSU unbranded
DDR2 ram, 2gig, 800
Geforce 8800 GT 512meg...
That should be all you need for this anyway... Any thoughts would be AWESOME guys...
