Upgrade computer no image on screen

Hey guys,

So i just bought a new motherboard and a new processor.

This is my specs now:

Intel i7 4770K
Asus Z87-A
Kingston DDR3 4GB 1333Mhz
Geforce 8800 GTS
Power Supply is a LC6600 5 years old +/-
Ive a chassis fan on the front and back

Everything seems good but i got no image on the screen. No red lights on the board now warnings no nothing, everything is connected good. Double checked everything. Out of ideas now.

Thanks for your help

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

In reply to: Upgrade computer no image on screen

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?

Still leaves the other 2 usual.

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

In reply to: Still leaves the other 2 usual.

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?

In reply to: The board was shorter

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.

PS. "1 x 24-pin EATX Power connector(s)
1 x 8-pin ATX 12V Power connector(s)"

PSU is fine

In reply to: So the cardboard no case test was not done?


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.

In reply to: PSU is fine

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