At first, the only thing that happened was that sometimes, after I closed the laptop to put it in standby and then later opened it, the screen would stay black. The power light would change from yellow to blue as if the computer had successfully resumed. When I moved the mouse or pressed keys, nothing happened, nor when I pressed the power button briefly (as if to take it out of a standby begun through the shutdown menu). Closing the laptop changed nothing; the power light remained blue, and re-opening it would still not wake it up.
Then, the screen started going black in the middle of using the computer, and would be similarly unresponsive. This has been happening with increasing frequency, and seems to mostly happen when I do something that increases the memory load. However, it does not seem to be related to how much the load is increased or how much the total load is; I have had it crash when I clicked the play button on a Youtube video, but I have played Civilization IV for hours with no incident. The problem seems to mainly occur when a new process is started, but it also happens randomly when nothing new is started.
Most recently, I have found that some program settings are reverting entirely to their default values after a crash. This has happened twice now; the first time it was Google Chrome that lost settings, and the second time it happened to both Chrome and Skype.
System: Windows XP Media Center Edition, Version 2002, Service Pack 3; I am completely up-to-date with Windows Updates
Hardware: Toshiba Satellite A105 -- S4094; all hardware is stock except for an upgraded hard drive
Antivirus: AVG Free Edition 9.0
Browser: Google Chrome
I run CCleaner fairly frequently; I have it clear index.dat, various IE history data, %26quot;Run...%26quot; prompt history, system search autocomplete, other explorer MRUs, recycle bin contents, temporary system files, the clipboard, memory dumps, chkdsk file fragments, windows log files, DNS cache, and various Firefox history data. It also clears data (though it does not specify WHAT data) from Adobe Reader, MS Office Picture Manager, MS Office, OpenOffice, Google Toolbar Firefox, Sun Java, Flash player, Quicktime player, Quicktime player cache, Real player, Windows Media Player, 7-Zip, AVG, WinRAR, MS Paint, Wordpad, and RegEdit. I also use CCleaner to scan the registry for errors and to correct them.
I keep AVG updated, and I run a scan almost daily.
What I usually have running at any given time is Digsby, Skype, and Chrome.
Does anyone know what is going on here?What is going on with my laptop?
wow could be any number of things, I would start by running some diagnostics tests on the hard drive and memory.
go to : http://www.ultimatebootcd.com and download the UBCD 4.1.1 ISO image and burn that .iso file to a CD using either NERO (right click on fight and select open with and then Nero) OR a program called IMGBurn if you don't have Nero (free download Google it)
this CD is to be booted to by restarting the computer with that CD in the drive and allowing the computer to boot FROM CD.
it may be necessary to go into your BIOS and change the boot order to prioritize the CDROM higher than the Hard drive.
I would suggest running DFT (drive fitness test) first to check out your hard drive. do the advanced test.
and then run memtest86 to check out your ram.
if those pass then you may unfortunately have a bad motherboard or LCD power inverter.
