I'm running win 7 64bit

New power supply, new SDD, New ram, 1 CDROM connected. AMD Phenom quad core processor

I've tried to boot the computer from windows disk which worked for about 10 seconds and then the display went out. No signal etc on monitor. I tried to reboot and still no display. I left it for about 15 minutes and it went to bios setup for about 30 seconds before completely freezing. Every time I power it up the lights an fan turn on. Is the processor dead?

This equipment listed is literally the only things connected to the system.
I've had so much trouble I have isolated it down to basic core components to start there.

Running an ASUS M4A78T-E Motherboard, 2 x 2GB DDR3 (Brand new), 700w Power supply (brand new), AMD II Phenom Quad Core w/ stock heatsink/fan, `120GB Mushkin SSD (Brand new), 1 CDROM.

Again, I have tried to boot windows from a CD but still lost display.

Could be overheating. Check the heatsink mounting.

I already removed the heatsink, thoroughly cleaned the old dried up compound, added new thermal compound and reattached the heatsink. Any thoughts? Im at a complete loss and would just like to know before I go and spend several hundred dollars on a new processor and motherboard.

Thanks

I don't have quite enough information:
a) motherboard, or
b) Power Supply, or
c) Monitor

I believe if the motherboard works, but the CPU doesn't you are supposed to get some beeps. However, I can't remember if that requires a speaker attached (I don't think so).

Troubleshooting:
1) swap the monitor (if no joy)
2) swap the Power Supply (if no joy)
3) probably MOTHERBOARD

*It's interesting that you mention a new Power Supply:
- Has it ever been verified working?
- Did you already have an issue and that's why you got a new Power Supply?

A: Beeps do require the speaker.
B: I doubt you will get any beeps without a working CPU
C: Motherboard is definitely suspect.

Yes this system has had many issues as I said.. this is a brand new power supply and the monitor is 100% working because I use it for multiple devices (cable TV, xbox, etc).

Disconnect the SSD and optical drive. If it still doesn't POST, try each RAM module independently.

Can you get to BIOS with this absolute minimum configuration?

look at the cpu support list and see what bios is needed to post with this mb. there are a lot of bios updates for this mb and it may be the mb you have has an old bios.

He has to be able to POST first to update the BIOS...

Also I'm not sure if it the bios because at one time it worked for about an hour. I can't even get to the bios screen with the current setup I have described.. There is no display

Are you using onboard graphics?

At this time yes I am using the onboard chipset to elimate a faulty GPU as the culprit. It will POST only Sometimes... When I am able to get nto BIOS setup I have about 10 seconds before the screen freezes. After I power down and back up.. no display.

sounds like bad power or a bad cap/vrm on the mb.
