dell vostro 1500 windows xp working fine a few weeks ago. was gone a few hours and came back and trouble starting up ever since. sometimes, just the power light comes on when i restart it, but not screen (usually, this'll happen many times in a row).
sometimes, it starts up, but either freezes sometime during the startup, or after startup when i try to open something.
a couple weeks ago it stayed on long enough that i did some virus searching, cleaning, defragmenting, etc. before it froze finally. for awhile it seemed to only freeze when i move the laptop, but the last couple days its freezing without me touching it too. i didn't worry much for a couple weeks cause the cleaning seemed to help (that was the phase where it pretty much only froze when i touched it). but the last couple days, much worse
other hints are the following messages i've received

blue screen saying "check adequate disk space. if a driver is identified in the stop message, disable the driver or check with the manufacturer for driver updates.
try changing the video adapters
check with the hardware vendor for BIOS updates.
disable BIOS memory options (caching or shadowing)
for safe mode, to remove or disable components, restart the computer. F8 for advanced startup, then select safe mode

memory address line failure at .....(numbers here)
to resolve this issue, try to reseat memory
decreasing available memory
the amount of system memory has changed
if you didn't change your memory...
to resolve this issue, try to reseat memory
F5, onboard diagnostics (i chose this option, and as a result got a blue screen saying no user memory available)

couple weeks ago, it came on long enough to do a symptom tree diagnostics test.
it passed all but the following sections of what i tested-
primary battery bay- battery charger test
primary battery bay- AC adapter info test

also, got the message "your battery is able to charge normally, however it is nearing the end of it's life". didn't think it was a battery problem, cause i didn't think a battery could cause computer to freeze or shutdown. can it? a pet chewed on the cable and may have messed up the wires a little, but i didn't think that'd affect the computer

got a new battery after that, and seemed to improve things for awhile. didn't get a new ac adapter cable (though tempting since it's chewed on) but problem happens whether using battery or ac power, so i assume that isn't it.

since things got worse last few days, finally decided i'd try to reseat the memory. did that. no improvement at all.

i always get the bios revision A04 message on powerup btw, not sure if that matters.
unlike before, i don't get error messages when it freezes. no sound either. it just freezes. then i start it up again. usually its fine for starting up again, but sometimes it powers on but the screen is black. i just turn it off and on until the screen finally comes on (usually about 5 times on and off).

today it wasn't starting up at all without crashing, so i reseated the memory again. after that, for the first time, it wasn't turning on at all. no lights, nothing. kept trying, then gave up for a couple hours. just tried again, and got lights but no screen (like i've had before many times), and then finally the last time i pressed power it started coming on, screen and all. but what came on is completely new. i now have a screen blue horizontal stripes. in between the stripes are red symbols (spade, smiley face, rectangles, double sided arrows) on a white background. the top of the screen has some black background mixed in. what is going on here? please help! not sure if i should shut it off again. thanks

the next time i started it up after that weird last crash with symbols and all, i got 2 fast beeps, and message "amount of system memory has changed. if you didn''t change your memory, try to resolve the issue. try to reseat the memory.
now its back to crashing when i move the laptop, or on occasion, crashing whenever. any ideas? thanks.

Let's take a look :thumbsup:

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Please do a new, full scan, with MBAM and post the logfile in your next reply.
Also do this please:

Please go to Kaspersky website and perform an online antivirus scan.
  • Read through the requirements and privacy statement and click on Accept button.
  • It will start downloading and installing the scanner and virus definitions. You will be prompted to install an application from Kaspersky. Click Run.
  • When the downloads have finished, click on Settings.
  • Make sure these boxes are checked (ticked). If they are not, please tick them and click on the Save button:
    • Spyware, Adware, Dialers, and other potentially dangerous programs
  • Click on My Computer under Scan.
  • Once the scan is complete, it will display the results. Click on View Scan Report.
  • You will see a list of infected items there. Click on Save Report As....
  • Save this report to a convenient place. Change the Files of type to Text file (.txt) before clicking on the Save button.
  • Please post this log in your next reply.
