My computer shut down on its own the other night and I couldn't reboot it..it WOULD freeze up. I had to run the virus scan on safe mode and it came up as my computer having a virus, which I cleaned. I ran the scan again and it came back as clean.

When I rebooted my computer, the desktop screen was white with a blue triangle and had an error message saying SOMETHING like "active desktop recovery". i found the solution to that problem on this forum and I think I have fixed that problem. But my computer kept crashing.

I ran the virus scan again and it came back clean. I ran a maleware scan and it came back clean. So I bought a registery cleaner (I think that is what it is called). the name of the SOFTWARE is Registry Easy. I ran that, cleaned up the fixes and I am still having PROBLEMS with my computer freezing up on me. I don't know what to do at this point. For example, since typing this message here, my computer has frozen up on me twice and I have had to reboot.

The operating system is Win XP home edition. It is a Dell desktop. Not sure what else you need by way of information but any help would be greatly appreciated. This computer is less than a year old.

I uninstalled and re-installed my browsers (IE, Firefox, and Chrome) and Chrome is the only that works. My computer is still crashing about every 10 minutes.When is the last time you opened it up and cleaned out all the dust bunnies ? ?
NOTE: A can of compressed air is the preferred method...do NOT use a Vacuum.
Remove all power to the machine and take anti-static precautions.1.  Overheating.  Following up on "patio's" suggestion to blow out the dust, you could also download some programs to monitor the temperature sensors of your computer.

2.  Safe Mode.  Boot Windows to Safe Mode and see if the problem follows you there.

3.  Memory DIAGNOSTICS.  Download the "free" diagnostic software at either www.memtest86.com  or www.memtest.org  and create the desired bootable media.  Boot the program and let it run indefinitely ( key to exit).  You should let it run at least two hours to test the memory.  There should be no memory errors.

Even if you don't suspect memory, it's worthwhile to exercise the motherboard, CPU, and memory independent of the Windows software to see if the problem follows you.  If it doesn't, look towards the hard drive with the software of the Windows boot (and other devices not used during memory diagnostics).Have you looked at task manager to see if there is anything using too much CPU or memory? Also try downloading ProcessXP. It is a task manager equivalent with additional features.
