Hi folks,
Looking for some advice on an issue I am having with my PC. It have had it for 3years with no issues at all, but recently when I turned it on the monitor did not come on. After more investigation it seems that BIOS does not POST - i.e. I don't get my usual beep when it boots. The CD drive and hard drive and fans and power lights are all powered but it will not boot.
I have spent some time on Google and tried the following:
- Power supply: multimeter shows that 12, 5 and 3.3V supplies are spot on. Also green LED on motherboard is lit.
- RAM - tried removing this completely, still no error beeps from BIOS
- Video card, HDD, CD drive all removed - still no beeps
- Reset the BIOS to default - no change
- Case does not have a reset button but the motherboard jumper is correct (i.e. its not held in reset)
- and yes - the monitor works fine tested from laptop
Any ideas as to what else I could try? My gut feeling at the moment is that the motherboard is broken however I have no idea why this happened - I have literally never even opened the PC case since I purchased it. The only other thing I could think is a processor problem, but I'm sure the BIOS would still detect this - is this correct?
