I am working on a desktop that locks up an won't react to any command or key combination.
I have tested memory and hard drive and they are OK. Am thinking it might be the processor but after placing an other processor the problem persist... which points me to the motherboard.
Now... my question is: Is there any app that can test the CPU and maybe other components besides the memory and hard drive?
By the way this comp has a "BIOSTAR :: MCP6P M2+ v 6.1" motherboard with 1 GB Ram and a 160 GB ExcelStor Hard Drive (basically an IBM reject

!!! err ...) with a Sempron CPU and... the rest...
It seems odd that I can trigger the look when I am using synaptic... sometimes it will go OK... most it will Frizzed... No artifacts on the monitor or anything, which to me means that the internal video card "might be OK" but I don't know...
Anyways I hate it when the hardware gives this types of failures... It looks OK until who knows what... well faulty hardware... This problem also happens on Windows XP, but way worse! Won't boot... just restart, not even its "Safe Mode" helps.
So... is there a way to use some app tool to get a definitive diagnostic on this cadaver? Am sure it is dying!
Thanks in advance!
