Do I have a Virus? Shutdown problem

[Guest the_best_of_fools]

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

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

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.

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

avenues asap.

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

the Power menu?
