This started happening three days ago, and happens about once every day, and now, once every few hours. After a certain amount of time, many programs will suddenly freeze, crash, fail to show a window, etc. For example, explorer.exe will become nonresponsive, internet explorer will crash, and when restarted, will lock up and become nonresponsive, windows media player will not produce a window (although wmplayer.exe is launched), and system restore will not display a window (although rstrui.exe is launched). Before the first occurrence, the programs work fine; however, after they experience that problem once, they continue to experience the problem. Also, they seem to be somehow linked; for example, if internet explorer crashes and fails to display windows properly/becomes nonresponsive, trying to use Windows media player later will not work either. I should also note that nothing is hogging the CPU during this time. However, some programs are completely unaffected. For example, Firefox 3.5.5 works completely fine, Office 2007 works fine, Process explorer works fine, along with most of my non-Windows programs. What Im starting to guess is that there is some problem with my graphics related to parts of the operating system and programs close to it, but Im not sure. Most of the time, simply restarting the computer doesnt solve the problem. I system restore to provide a temporary fix by going into Safe Mode and starting system restore from there, back to long before the problem ever occurred. The problem is often gone for a day or so, but then comes back, even though Ive restored back very far. Ive also tried booting from the Last known good configuration, but that doesnt help either. I also cant seem to find a definite trigger for the problem; sometimes, its opening a new tab, sometimes I just try to launch a program, and the problem starts. Again, this problem just started a few days ago; its never occurred before. Also, I havent installed any programs, changed settings, etc, for a long time. Some computer information that may help: Dell XPS M1330 Intel Core 2 Duo T9500 2.6 Ghz processor 3.50 GB RAM Windows XP Service Pack 3 Nvidia GEForce 8400M GS (256MB) DirectX 9.0c (4.09.0000.0904) Internet Explorer 8 Explorer.exe version 6.0.2900.5512 GDI32.dll version 5.1.2600.5698 My apologies if it isnt enough; if needed, Ill supply more information. Anyway, if you have a solution to the problem, I would greatly appreciate it! Thanks.1 person needs an answerI do too

Run Check Disk Now Check Disk REPAIR Hard drive - THROUGH CHEKDISK command Try this, when you first turn the computer on, right before the windows xp startup screen appears, continually press F8 until a menu appears. Select "Command Prompt" from that menu. When you get to the prompt, type the following and press enter: chkdsk c: /f /r NOTE: the /f command automatically fixes any errors encountered, the /r command locates bad sectors and recovers readable information 5. A reboot is normally required for the Chkdsk program to lock the disk and run correctly, so simply restart the computer and Chkdsk will run automatically. When it's finished, (This process can take quite a while depending on the size of your disk, etc.), it will boot back to normal Windows.
