Computer will turn on but I see nothing on my monitor..

Iomega0318 · 06-05-2008, 08:20 PM

Hey guys it's me.. again lol,
I didn't exactly know where I should post this so I figured this might be a good place..

The computer "will" turn on and the CPU fan will kick on and stay on, I checked the thermal paste and it seems fine, should I still replace it? Anyways on to the problem, the computer was working fine and I turned it off to move it I did not unplug anything except the power and moved the whole desk with everything on it plugged it back into the wall and then boom dead.. I thought it may have been the PSU so I replaced it since I had been meaning to anyways, switched it from a 400W to a nice 580W power supply.. And still the same thing, computer will start and stay on with everything inside running fine but I still receive no video signal, I tried pulling to graphics card out and using the motherboards built in one and still no go..

Any ideas?

Try another CPU. See if it works, make sure the socket for the mobo marches with the cpu u r gonna try. That happened to me last weekend, and just found out today that the problem was the cpu. You might also want to try another RAM stick

Iomega0318 · 06-05-2008, 08:40 PM

Ouch, that is really going to suck if it is the CPU..
The only other one I have that matches the motherboard is one I bought to replace it a long time ago but never got the heatsink for .. Anything else it might be that I can try without replacing it just yet.. I will go ahead and look for a heatsink for the other CPU though..

angelr10 · 06-06-2008, 12:09 PM

Cant you use the same heatsink for your old cpu?

Iomega0318 · 06-08-2008, 02:06 AM

I am not sure if it is rated to cool a 3.12 GHz CPU, it is only cooling a 2.26 GHz one right now..
I would rather not try and end up damaging the processor..

Iomega0318 · 06-08-2008, 08:05 AM

Ok.. well I got around to switching the CPU, and I can now say it is not the CPU..
So any other ideas?

angelr10 · 06-09-2008, 08:07 AM

Have u tried another stick of RAM? If it's not that, I assume it is the mobo then.

dai · 06-09-2008, 02:11 PM

what
video card
cpu
m/board
power supply
brand
wattage
are you running
any error message
check your tempretures and voltages in the bios and post them

Had this happen one time. Turned out, the cable on the back of the monitor was pulled out just enough to cause it. Sometimes its just that easy.

Here is the motherboard:
Biostar P4M80-M4 VIA P4M800 Socket 478 mATX MB w/VID & SND
http://www.geeks.com/details.asp?inv...M80-M4&cat=MBB
The power supply:
Echo Star 580W 20+4-pin Dual-Fan ATX PSU w/SATA
http://www.geeks.com/details.asp?invtid=ESTAR-580-24
The PSU that came with the computer shorted out about 4 months ago, and I had been using a spare until the computer went down and I thought it may have been the PSU again so I went ahead and replaced it..

As for the video card, I can't exactly remember what it is, but I do know it is an ATI card..

And I cannot get anything on the monitor at all, not even the boot screen..
So I have no idea if I get any errors or not..
Hope that helps if you need anything else I will do my best to get it for you..

i would be checking this out
Echo Star 580W

Iomega0318 · 06-11-2008, 10:11 PM

I just purchased it though, could it really still be the problem?

dwalk1989 · 06-11-2008, 10:12 PM

I had this problem recently because I had been fiddling around in the BIOS and messed something up and it would do the same thing you descriped in your first post. I pulled out the battery in the motherboard and reinserted it a few minutes later, resetting the BIOS, and it booted up fine.

Nope just tried it..

turn the computer off
remove the power lead from the back
take the side off
remove the cmos battery
move the cmos jumper from pins 1 and 2 to pin 2 and 3 and the back to pins 1 and 2
replace the battery
put the side on
replug in the power lead
boot the computer

there can be 2 solder points you touch with a screwdriver
2 pins you touch with a screwdriver or use a jumper
a cmos clear switch or button
there will be a diagram and instructions in your manual
have you checked what the video card is yet
