Leaving the computer off for 1 hour before it boots up properly should tell
you what is causing the problem - heat! The computer cools sufficiently in
that time to allow proper operation.

Check that all the fans are spinning freely when nudged with your finger.
Listen for any mechanical noises, other than air flow. Look for clogged heat
fins in the CPU heat sink and the video card heat sink. Make sure the fan in
the power supply is spinning and that the P/S is not clogged with dust
bunnies.

Hi guys and gals

I really hope someone out-there can help me as I at my wits end over
this problem:cry::cry::cry::cry::cry::cr y:,
where do I start........mmmmm... so as far as I can remember it all
started after an update for MS office + gfx driver and then all the
problems began, mainly my PC won't start up properly, no signal to any
of my monitors, my mouse and keyboard don't work, blue and green lights
on my tower running constantly and fans on full.
The only way I can get it to boot up properly is to do a hard re-boot(I
have to leave it unplugged for at least an hour to do this) and has been
like this for almost a fortnight now, I have already tried 1). restoring
it to before the update. 2). CHKDSK. 3). repair with installation disk.
4). changing power options. 5). un-installed Microsoft Office.
5).updated to most recent nvidia graphics card drivers.
Can't think of what else at the moment but have been going through the
forum and google to no avail..... so can anyone help


many thanks in advance Mic
