Boot Up issue--sign of infection?


Recommended Posts

This morning, my PC did not boot properly....

 

My monitor and speaker system are turned on separately first. I then power

up my tower; after that the cable modem and router.

 

This morning, I went thru the above routine....monitor did not have anything

on the screen, but I could see the led's on the tower all working. Nothing

on the monitor. The light was blinking, but nothing. I powered down the

entire system...everything.

 

I turned everything back on; this time the system booted up, on the the

bottom of POST, just after the system components show, the was a message

that said "the system failed to boot several times. Hit F2 to reconfigure or

to get into BIOS"....well I did neither and the system booted fine.

 

Several days ago, I turned my system off, but left the modem and router on

so my husband could use the internet connection. Later in the day, when I

went to power up my PC, the PC exhibited the same behavior exhibited this

morning.

 

I have WinXP SP3; Super-AntiSpyware; Ad-Aware; Spybot S & D; Comodo firewall

and AVAST, and hardware firwal in the Netgear router.

 

I am asking about malware or trojan or virus here because someone on a

hardware forum suggested my PC could be infected, but I could find nothing

in the scans I ran.....and, no other symptoms.

 

Thanks.....

Hello Diane:

 

Is the age of your system well beyond three years old? Your system's

motherboard CMOS battery becomes a candidate for replacement as systems

age. Some CMOS backup batteries don't make it to five years. YMMV.

 

You have a good lineup of antimalware in your arsenal and the only

additions I'd make are MBAM (as a partner with your SAS) and MRT if you

forgot to mention it. Some might add GMER for periodic rootkit checks,

and others might add Windows Defender.

 

You might wish to schedule a chkdsk scan for some future boot-up.

 

If your system has an actual video board, reseating it wouldn't hurt.

The cable that runs between your monitor and the computer could be

unplugged and replugged to clean the pins that carry the video and sync

signals to your monitor. If you /do/ have an actual video board, it

could be in the early stages of failure.

 

Opening your computer to check for excessive dust might also include a

check of all your system's cooling fans.

 

If any of the hardware checks give you a feeling of dread, many self

guided instructions can be had with Googling.

 

Thank you for the lucid description of your trouble. We don't

frequently see this. Tell hubby you deserve a hug. Please post a

follow-up with progress.

 

Best wishes,

 

Pete

Hi Pete:

 

I ran all the security software again ....nothing found.

 

The first thing I thought of was CMOS battery. The mobo and chip are June

2007, but it they seems a bit too new to be acting up. We refurbished this

PC back then. The "C" drive is 18 mos old or so and "D" is 6 mos old.

 

It was also mentioned to me by another person in the forum, that he had a

similar problem to mine, but his was caused by a flaky PSU, an Antec to be

precise. Guess what mine is...an Antec 650W; so, it was suggested that I get

SpeedFan which I did. I figured out how to check the disk drives as SMART

was enabled; they passed. The fans ran pretty steady at 2130 or so; But,

reading the voltages threw me a bit. There was flucutation, but it seemed to

me to be minor and then settled down. I am not sure what I am supposed to

see, but I will have familiarize myself with the use of the software. I will

Google it and I'm sure I'll find the answer

 

I do have a video card, Nvidia 8600GT, but I haven't done anything with the

driver for a couple of months. I have PSI and use Firefox as my browser; and

the only thing that has come my way for updates has been Java and Firefox

and of course the Windows updates.

 

I thought of the monitor and videocard connections and the dust. Cleaning

the pins is a great suggestion. I thought of an overheating CPU, but my

specs call for 45-65C and this chip runs at 50C, but the PC had just been

turned on and wouldn't have overheated that quickly. The hub is the go-to

hardware guy and after a hug(like you suggeested), I'm sure I can con him

into getting inside the case for me. I am no hardware person and he's redone

the inside of this PC for me umpteen times.

 

I also ran memtest...no errors found. I use MRT at WUpdate time and just did

use it after the lastest update. I'll do the MBAM thing though. Thanks for

that.

 

I think I'll have him do voltage checks at bootup and check the battery

while he's got the PC open. It's so frustrating when the prob is

intermittent like this one.

 

Have a great day and thaks for your suggestions.

Hello Diane:

 

I too recently tried SpeedFan and although it wasn't compatible with the

mobo I tried it on, it appears to have good promise. I'll need to let

the author know what my hardware setup consists of.

 

Memtest86+ is probably the top in its category.

 

An excellent companion utility to Secunia PSI is FileHippo's Update

Checker. Both are in the "must have" category now.

 

If you ever feel like taking SMART monitoring to the next step, try

looking at smartmontools.

 

Judicious (but careful) reseating of the other usual suspects might be

fruitful.

 

Lest you forget, the Nvidia video board should be reseated while the

case is open. Also, it's a good time to carefully look for electrolytic

caps that are swelling or leaking. Badcaps has very good photos.

 

<http://www.badcaps.net/>

 

Another "divide and conquer technique" is to exchange monitors (or other

suspect components, with your husband's system). I'm sure he'll never

notice. :-)

 

After doing your check/replacement with the CMOS battery, see the following:

 

Three notes regarding your bios in passing: 1) Remember what keystroke

would be required to go to your computer's bios setup. Hence, if you

sense that your /not/ going to have video, if you allow the boot to

continue, go into bios so you won't need to probably depress and hold

your computer's power button for recovery. 2) Go into your bios setup

and record any non-default settings you may have changed to. Try going

to the default setup and re-enter any custom changes made. 3)

Hesitantly, check to see if your computer's manufacturer has issued an

applicable BIOS update. However, if it doesn't directly address a

current problem, I'd probably forget about it; "Here there be dragons!"

 

I would say that you have a good start on your list of due diligence

items.

 

Googling might give you the acceptable voltage limits for your system's

particular mobo.

 

What kind of monitor are you dealing with - make/model and age?

 

If you wish, keep this thread going although we're way displaced from

malware issues, or if you like, move it to the previous forum.

 

Best wishes,

 

Pete

There is also the possibility that the boot code is ready to access the

boot disk before the disk is fully up to speed. Sometimes you can avoid

this by energizing long enough to get some good spin and then a quick

off/on to start the post again. Sometimes there is an option in the bios

setup program that allows setting a delay to allow more spinup time

prior to attempting to access the disk.

 

Sometimes a more powerful power supply unit is suggested - but this

usually occurs when someone adds an additional drive that pushes the

specs a little.

Hi FTR:

 

I believe the OP stated that her monitor's display remains entirely

black throughout a failure. Even if the hard disk drive were missing,

the BIOS splash screen or possibly a line or two of BIOS information

would still make it to the screen.

The OP's power supply is not in the clear yet. They're going to try

some further tests in that regard.

Lots of info - I thought I read something about the monitor being black

with something blinking. I assumed the flashing cursor. I probably

misread the post - hard day at work.
