Hi every one,

I've been experiencing a weird problem with my computer recently. When I
turn off my computer, the light on my monitor will go from green to the
orange standby state and the computer will shutdown normally. But after 60 to
90 seconds, my monitor light turns on green again and the power 'on' light on
the front of my tower flickers really fast as if the computer was turning on
and off and on... I can also see the fan at the back of the computer turning.

Any idea? I my computer corrupted?

thanks,
tbof
 
Re: Do I have a Virus? Shutdown problem

This sounds a little like poor electrical connection/s somewhere, probably a
mains kettle lead not firmly plugged in somehwere !
Are the mains kettle leads, (if yours is a desktop PC), all firmly plugged
in ?
If not a laptop or notebook, and with mains power disconnected - Check all
power connectors, including motherboard power connectors, and all pin header
connections to make sure they're good and secure.
While you're "in there" disconnect motherboard power supply connectors and
examine carefully for any sign of scorching or overheating esp. on the pins
that carry lots of current e.g. red and black. (never switch on the mains
power with these disconnected by the way!).
Check for correct function of the case front "power up" button, (using a
multimeter, check resistance i.e. when not depressed, the "power up" button
should be fully open circuit).
If all seems fine but, the problem persists, you might like to try swapping
out the psu.

regards, Richard

Always state your full Windows version (e.g., WinXP SP3) when posting to
this newsgroup, please.

Run a /thorough/ check for hijackware, including posting your hijackthis log
to an appropriate forum.

When all else fails, HijackThis v2.0.2
(http://aumha.org/downloads/hijackthis.exe) is the preferred tool to use (in
conjuction with some other utilities). HijackThis will NOT fix anything on
its own, but it will help you to both identify and remove any
hijackware/spyware with assistance from an expert. **Post your log to

http://forums.spybot.info/forumdisplay.php?f=22,
http://castlecops.com/forum67.html, or other appropriate forums for review
by an expert in such matters, not here.**

If the procedures look too complex - and there is no shame in admitting this
isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA or Geek Squad) computer repair shop.

I think that reply is far fetched.

As the OP stated "computer will shutdown normally" indicates that the OS is no longer
running and at this state one must conclude it is hardware related.

In this case the OS isn't important, the make and model of the system is.

Try unplugging any externally powered USB hardware, including any hubs or
hard drives. I have seen this happen when a broken or badly designed USB
device was feeding 5 volts back into the computer.

The same can be said for any Ethernet cabled device like a cable or DSL
modem.
 
Re: Do I have a Virus? Shutdown problem

Thanks to everyone for your input. Will look into all of these possible
avenues asap.

Re: Do I have a Virus? Shutdown problem

Could my problem be in the BIOS configuration? What should it ne set to in
the Power menu?
