Re: strange computer problem

first thing, remove the CMOS battery and leave it out for about 2 to 3 minutes.

if possible, try ALL of your system critical components (PSU, video card, RAM, CPU) in another motherboard to see if they work in another board. if they do, then your board is dead. if ANY one of these components does not work, then you know it's that system component that's causing this.

also, unplug any unnecessary fans or coolers. only the CPU and North Bridge fans should be powered up. case fans need to be unplugged from where ever they're plugged into.

for a system not powering up like you are describing, this is really the only thing you can do for testing.

Re: strange computer problem

keep at it then. try the PSU, CPU, and RAM next if these parts are available. or try these same parts, including your gfx card, in another machine if possible.

Re: strange computer problem

Seems to rule out the monitor...... Do you have a different PSU you can try?

Re: strange computer problem

It's mostly to point out a mobo issue, if a good PSU has the same fault then it's mobo/agp slot problem. If it works with the good PSU then part of yours went down. Easier to find a spare power supply than a mobo usually, that's why I asked.

With the system's reaction to the CRT monitor I think your LCD may not be the problem.

Re: strange computer problem

Many power outages due to storms begin with a huge spike, way over voltage. Unless your system is on an isolation transformer something's going to get burnt. (most UPS's are okay too) Those little power strip/"surge protectors" most people have really don't do much for this.

Living in Ohio I learned long ago to shut it off, unplug and wait for the storm to pass. You wouldn't believe the burnt stuff that used to come into the shop a day after a storm.
