I have a client who I built a new PC for in March 2011.
The hardware is:
Gigabyte Mainboard H55M-D2H
RAm - 4Gb
Hard Drive - 1,000GB Sata
CPU - Intel Core i5-760
Graphics - Nvidia GeFroce GT220
Power Supply - Thermal master 420W
Dvd Burner Drive
The issue is that every so often, maybe once a week, when they go to start the computer up, they push the power button and the fans start but there is nothing on the screen. It is as though the computer is not booting. I had a look at it when this issue first came up. i disconnected the power cord and reconnected, nothing, then I disconnected the HDMI cable and put a VGA cable on and it came up and booted into Windows 7 fine. i assumed it was a faulty cable.
It worked for a few weeks then did the same thing again. Press start button, Case starts but no signal to monitor. I replaced the graphics card, no change.
Disconnected Power cable for a few seconds, no change.
Did it again, the computer starts up.
It seems a very odd issue.
It has done the same thing again the other day. I am not sure what the issue is, so I have told the client I will replace the entire case for them.
Has anyone else had such a ridiculous issue?
I have also checked the mainboard BIOS and it is up to date!
