Have an 8 year old AMD Athlon PC running XP and some 2 weeks ago the monitor started showing "No Signal" when PC booted up. Tested the monitor with my laptop and it works OK. I assumed the graphics card had given up the ghost so bought another. Put it in yesterday but still "No Signal" is showing. I cannot load the driver CD as not even the boot up screen shows. I'd be grateful for any advice. Thank you.
PSU or motherboard failure? Try a different PSU and you could try clearing the BIOS to factory defaults by either using the pins on the motherboard or by removing the battery for a couple of minutes with the PC turned off and unplugged.
Ditch999 - thanks but I'm a bit unsure what you mean. "PSU" presumably = Power supply, but as the lights go on - see above - that should be OK? Would you kindly advise in simple terms what the "pins on the motherboard......" means. I'm afraid this is a bit technical for me! Thanks for taking an interest.
Beside the round silver battery the size of a 10p piece, is usually 2 or 3 pins named CLR_RTC or CLR_CMOS. Shorting these pins (creating a connection) for a couple of seconds resets the BIOS to default settings. Removing the battery has the same effect.
As woodchip says just because the lights are on doesnt mean the PSU (Power Supply Unit) is working ok.
