The 8800's are failing now.

And you have a very old PSU. Try the onboard video (no, I didn't hunt down your system parts) and two other things.

1. Old PSU.
2. Old video card.
3. The usual forgot to remove ALL motherboard mounting posts to be sure only the ones we need are installed gaffe.

8800 is working
by Pride1922 / February 18, 2014 9:47 PM PST

hey, thanks for your answer.

My graphics card is working, just tested it. Old system works. Anyway i've already tested with onboard graphics card and it still gives no signal on the screen.

Any other ideas?

Did you try it on cardboard? I don't know how many times I find an extra mounting post or that hilarious documentation error where the reset is marked fine on the board but not in the manual.

Here's a link about one of those.

"Also, use only as many standoffs as your type of motherboard requires. If you have any additional standoffs underneath the motherboard that don't line up with screw holes, remove them. Extra standoffs underneath a motherboard can cause a short or eventually wear their way through a trace and damage the board."

The board was shorter
by Pride1922 / February 18, 2014 10:12 PM PST

The new board is shorter so i removed the extra pins prior to mounting, ive checked the cpu and the board pins and all seems perfect. I've tried to power it on just with Board processor and ram, using the onboard graphics card. Still its a no show. I've cleared the cmos and unplugged the battery.

I tested my old system and it works. So my only guess atm is the PSU not beeing able to power the system.


The onboard led is green and no other led is turned on.

So the cardboard no case test was not done?

Odd. It's the standard of tests for this.

I didn't mention things from the manual I always see them get right such as the CMOS clear jumper location and such. The 8800 should be the last thing to install.

OK, how about power connections. This looks to be the usual 24 and 8 pin power (two connection) board. Five year old power supplies rarely have the 8 pin power plug.

PSU is fine
by Pride1922 / February 18, 2014 11:12 PM PST

Hey,

So i went to the store, tested everything and the system runs fine with another processor.

So i was unlucky to get a faulty processor.

Thanks for your help. Really appreciate it.

Just a parting tip.

Always get the CPU in a sealed box. Tray/OEM deals are nice but can be troublesome at times.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
