Hi all,
My parents computer started randomly freezing up a couple of days ago and it gradually got worse to the point where now it won't even show anything on the screen.
All of the fans and the hard-drive, etc. boot up OK, the motherboard light is on, but none of the keyboard/mouse lights work and nothing is displaying on the screen. I also don't hear any beeps when it starts up.
So far I have tried a different GFX card, RAM and hard-drive but it still won't display anything.
I have tested the PSU using a multimeter and the 5v and 12v rails are reading OK; I'm not sure how to check the 3v rails.
The PSU is a Corsair and it's only 6 months old so I doubt it's that. If the 5v and 12v rails are reading OK, does that mean it's probably not the PSU?
I'm suspecting it's either the CPU or motherboard now but I don't have any spare to test it with.
What do you think it is and what should I do next?
To be honest this PC has been a pain in the backside. It blew up just 6 months ago and I needed to replace the PSU, motherboard and RAM.
Here are the specs:
Intel P4 Northwood 2.6Ghz CPU (Socket 478)
ASUS P4P800SE Motherboard
512MB Kingston RAM
nVidia FX5200 GFX card
Corsair CX 400W PSU
Maxtor 120GB hard-drive.
As you can see it's quite an old machine now, except for the PSU which is newish. I'm tempted to just upgrade the CPU, motherboard and RAM.
