Can't boot system - monitor display is blank

June 16, 2009 at 18:16:01
Specs: can't get to BIOS even nevermind Vista, 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)
Hi all - I recently completed a self build for the
first time. I was feeling good about it until it
wouldn't start. The monitor is brand new too
so its possible thats faulty, but it IS giving me
a "signal not found" after briefly displaying the
ACER logo every time I turn it on. Other than
that, the fans work (2 cooling + a CPU fan),
the DVD drive works, and both boards flash
the proper colors (MOBO green, Radeon Video
red). It sounds fine although I can't prove the
Hard Drive is working either. HELP!

Here are the specs:

MOBO - ASUS M4A78 Plus AM3/AM2+/AM2

CPU - AMD Phenom II X2 550 Black Edition
Callisto 3.1GHz 2 x 512KB L2 Cache 6MB L3
Cache Socket AM3 80W Dual-Core Processor

Video Card - HIS Hightech H489F1GP Radeon
HD 4890 1GB 256-bit PCI Express 2.0 x16
HDCP Ready CrossFire Supported Video Card

HDD - Western Digital Caviar Black
WD6401AALS 640GB 7200 RPM 32MB
Cache SATA 3.0Gb/s 3.5" Internal Hard Drive

DVD Peripheral - SAMSUNG Black 22X
2MB Cache IDE 22X DVD±R DVD Burner with
LightScribe - OEM

Power / Cooling (besides case + CPU) - PC
Power & Cooling Silencer PPCS500 500W
ATX12V / EPS12V SLI Ready CrossFire
Ready 80 PLUS Certified Active PFC Power
Supply compatible with core i7

Any help is appreciated.

I can see the processor, dvd, video card and hard disk, however, the RAM appears to be missing in your list. Is that simply a typo?

He appears to have the correct memory's in the CPU/Ram header of his original post.

Gotta ask if the power connectors are plugged into the card? It's a good psu but I wonder if 35a on the +12v rail is enough to run everything.

I'd be curious to see if the machine would boot with a more modest video card.

You can only use a single 1066 frequency Dimm on that motherboard, your specs list 2. Try booting with only 1 DIMM

Tried bootin with 1 memory stick to no avail...Brought it to the
Geek Squad at Best Buy for a 5 min free checkup...He seemed
to think it was most likely video card but could be anything
(Mobo/CPU)...HDD and DVD seemed to be fine...I think my next
move is to send back the video card and get a new one...I would
love to try with a diff video card but I dont have one...I would have
to ask around my friends, I dont think any of my good friends
have them.
