My screen displayed a strange orange and pink fine checkerboard/herringbone
pattern today. The display then lost it's feed as if the pc had been turned
off but all case fans etc were still running. I pressed the power button and
the pc turned off immediately. I powered up again and the POST started with
a beep as normal, followed by another indicating a RAM issue. I took one 1Mb
RAM stick out and tried again but still with the RAM beep. I swapped the RAM
over for the other stick and nothing, not even a POST. I put the original
RAM in and tried again but still the same, no POST. I've swapped the
graphics card for another but still the same problem. I had what I thought
was a RAM problem (1 beep) around three weeks ago and got the RAM swapped as
it was only 6 months old - the problem seemingly cured but now it's reared
its ugly head again.

All lights on the case etc light up as normal, all fans run too along with
the hard drives. I've also tried taking out each PCI slot card in turn but
still no POST so could the CPU or mobo be the problem and if so, how likely
is it? I must admit, I'm leaning towards the CPU because for a P4 it has
seemed very lethargic for the last six months or so, with many fairly easy
tasks for it taking ages to complete.

Mobo - MSI 848P NEO-V
CPU - Intel P4 3GHz Northwood Socket 478
Graphics -ATI Radeon X1600SE
OS - Vista Home Prem.

Thanks in advance.

Maybe a compatibility problem with your 30 pin 1M simm and the mobo?

More seriously, 'Computer cannot boot up' thread has just addressed
same question.

Doubt it's that as was running before.

Thanks for that....I'll get on to do what you suggest now. I'll post again
