Socket 775 System no display

post #1 of 10
Thread Starter 
I'm trying to figure out the cause of this system not displaying video.
It was working fine before, now it won't show display when I turn it on.

The CPU fan spins up really fast, and then throttles down to a really low RPM.
There are no beeps, but I get RAM error beeps if I take the RAM out.

Motherboard: P5LP-LE (Rev 5.83)
CPU: Pentium D 3ghz
Video Card: GV-R465OC-1GI (Radeon HD 4650)
Power Supply: HIPRO HP-D3057F3H

I took the heatsink off the CPU and it was there was heaps of thermal paste, far too much, in my opinion. I also unplugged everything except for the CPU and one stick of RAM, still no display. I also reset the cmos.

The power supply has a max output of 300w.

Plug your monitor into the onboard VGA port and try to boot. When I upgrade the video card in my PC (sig rig) I had no video. I switched back to the onboard video, set the video adapter to PCI-E (it was set to "Onboard") plugged the video cable into the 4670 and it worked fine. Just a BIOS setting.

Report back.

I've already tried using the onboard video. I forgot to mention it came with onboard VGA.

"I also unplugged everything except for the CPU and one stick of RAM"

I'm currently testing the RAM, in other another machine.

The RAM tested fine in another machine, using memtest.

I also tried a zalman 600watt power supply, still no display.

Going to try and test the CPU at a friends place this week.

Try de-energizing the board. Pull the plug and cmos and then hold the power button for 30 sec.

If that doesn't work, throw it in the oven @ 400*F for about 7-8 minutes.

I had the same issue earlier, also with a 775 board. After thorough testing and swapping out everything for known working parts, my problem turned out to be the mobo itself.

Its the oven trick. Search my posts, I revived a dead monitor this way. Its last resort obviously, but if it doesn't work correctly or is completely dead its worth a shot.

I had this strange issue before on my 775 system... i had a new rig working fine but when i replaced the CPU cooler the monitor didn't show anything.
looked everywhere , unplugged everything still no use. i looked over the MOB and i noticed there was a Curve diode on it , once i straighten it the monitor started to post.

please go over the MOB and search if there is any inflated diode or curved one ....
