Signal lost usually means the cable is lose that connects the monitor to the back of your computer.
with the computer off and unplugged , disconnect the monitor cable from the video port on the back of the computer and physically inspect the pins to make sure they are not bent on the monitor end.
some monitors have the same plug on both ends , so it doesn't hurt to check the monitor side of the cable.
Once the cable has been checked, if the cover is off the computer, i would check all cables and add-in card to make sure they are fully in thier slots and ports.
check memory for the same issues.
If your monitor is a multi-function device , make sure you didnt forget to hit the source button on it , could be on the wrong input.

    If the hard drive activity light is staying solid, its showing you that something is keeping it busy.

    this could be a virus scanner set to run at startup, a program or virus, or windows try to check the system or hard drive.

    tell me, when you replaced the hard drive, is it internal or external? Did you set the jumpers correctly on the hard drive? Are all cables connecting the hard drive and other devices inside snugly in thier slots? Is the RAM seated correctly or the video card loose in it's slot?

    pull the cover back off the computer and physically inspect these things.

    we have to get a picture before we can work in the operating system.

    then post again here and we go to another step.

That problem would either be with your video driver or your video card or both.
I suggest looking up your audio device whether it be a card or onboard.
If its onboard, the manual for your motherboard will have it.
Update the drivers.
If its the video card faultering, i suggest buying a new one that fits your motherboard.
The socket size for your video card will also be found in your motherboard manual.

Xp s/3 windows hard drive has computer virus -- something S.M.A.R.T WANTED ME TO BUY THEIR PRODUCT SO THEY COULD FIX WHAT THEY CAUSED


hey, yeah just spyware its annoying i remove them daily,
i will run through some basics to try and get rid of the screen so u can get a virus checker on to remove the rest.
ps even if u buy it you will still get problems so please dont lol.
first thing is go into safe mode, you wont be able to get it off in normal mode as its still running.
once in safe mode, goto start msconfig, click startup, look for the virus in the list, write down the location of where its stored,
you then go into my computer, you will have to set it so u can see hidden files on the pc,
once u find the file delete it and it will stop it from appearing on next start up. then try installing www.superantispyware.com .
if its too complex for you try downloading the program and virus checker to pen drive, load safe mode and install it in safe mode and do a scan in safemode, ;) hope this helps

Userinit.exe application error


Hi again:

I would suggest that you may have a virus / spyware infection that has infected this windows file.

If you can boot into SAFE Mode ( reboot the computer) and when the screen goes to the black background with white writing start pushing F8 - keep doing so until you get a screen that gives you a list of things you can do -
ie:
restart windows normally
safe mode
safe mode w/networking

use the arrow keys on the keyboard and choose to boot into safe mode.- may take a couple of minutes

once there i would suggest running virus / antispyware scans as well as running a BOOT SCAN (a type of virus scan that scans the hard drive before it gets into windows)

NOTE on running virus/spyware scans - ALWAYS QUARANTINE the file infected - DO NOT DELETE - if you delete a critical windows system file you will cause windows to completely crash and in that instance you would have to reformat the hard drive and reinstall everything.

Screen locked up, turned computer off, turned computer back on, fans running, monitor won't come back on, and keyboard won't respond


Hi hay783...
Sounds like you may have a virus/trojan/worm/etc...
--------------------------------------------------------------------------------------------------------------------------------------------
To remove a virus,trojan,worm,etc from your computer...do it the EASY way...let someone else do it for you.
Start your computer, as the computer is starting keep tapping the F8 Key.
This will start the computer in the Safe Mode.
Once in the safe mode go to the following webage below and download,install, and run Microsoft Safety Scanner for FREE.
Once you run the Microsoft Safety Scanner (it may take quite a while depending on the size of your hard drive) it will remove all the virus's,trojans,worms,etc it finds, if it does not completely remove them all you will be given a chance to chat with a Microsoft Professional thru a pop open window and he will take control of your computer (with your permission) and finish removing all the rest of the virus's, trojans, or worms that are on your computer for FREE!! Can't beat FREE!!

Hi There,

Your problem has likely only 3 sources.

1. Corrupt Boot Files in Vista
2. Virus
3. Hard Drive locking up.

PLease boot into Safe Mode, download Malwarebytes Free Edition malware remover, stay in Safe Mode and run it there.

If no viruses are found for you to remove, you nedd a Vista Program Disc. Boot from the Disc and use Repair.

If no luck there, return to Safe Mode and use Sytem Restoego back to the earielst point in time in the past when you remember you puter running correctly.

Failing in all these, you likely need a new hard drive and start fresh.

Remember,

DON"T SHOOT THE MESSENGER!

Regards,

Selk

I beleive that this is a virus. some Viruses corrupt the device settings on a mouse or keyboard. you will to try to boot the computer in safe mode. to this when you tun the computer on press the F8 btton on the keyboard. then select safe mode with networking and hit enter. when the computer boots up you will need to run a virus scan. another option is to take the hard drive out of the computer and put it in another computer and run a virus scan on it. Viruses that usually cause this type of problems are redirect viruses found when searching on google.

My eMachines T3882 with Windows XP just reboots over and over


Sounds like a sick hard drive. When it starts to reboot, press F8 and choose Windows Diagnostic Test. It will show a hard drive failure if one exists. If it finds a hard drive error, the hard drive is junk and needs replacing. Once replaced, you can run your restore/recovery disk to install Windows back to the condition it was in when you bought it.

When the computer starts up. "Gateway" appears on the screen. Then the computer freezes. None of the reinstallation discs do anything. How do I fix this?


Reboot and keep tapping on F8 to go to Safe Mode. Do not put the reinstallation disk yet. Once in Safe Mode select "last known good configuration".

You can also run "Chkdsk" from the C hard drive Properties if you get to Safe Mode. Double click "My Computer", right click on C drive, select Properties, select Tools tab, go to Error checking and click on "Check now" then check "automatically fix file system errors" and "scan for and attemp recovery for bad sectors" and click "start"

If that doesn't work proceed to do System Restore in Safe Mode or remove previous programs that may have caused your Windows to freeze. If you suspect virus, run your anti-virus in Safe Mode.

If none of the above works then try your XP CD (or reinstallation disk) and do a repair.

Xp wont start on sony vaio v94vq


Try booting into safe mode completely. Then shut down completely. Unplug for a couple minutes and plug back in and see if it will boot normally. If not, then go back to safe mode and use a restore point in XP. If that does not work then either XP is corrupted or the hard drive is going bad. You can try restoring your system with the restore discs. NOTE: This will erase all data, pictures, letters, financial info, etc. you have saved.
If that does not work then you can try replacing the hard drive.
Hope this helps!
