Serious freezing issues, can someone plz help?

I'm having trouble with my computer freezing during various applications including disk clean up, defrag, and even during boot up. The first time it happened was during World of Warcraft (yes, Im that dork). Now It happens ALOT during WoW, and to try to get my computer back up afterwards is a real pain in the southern regions. I'm almost ready to just trash my computer so any help is almost a necessity in order to keep this thing alive Lol. ((((((((((((((((PLEASE HELP, IM DESPERATE))))))))))))))

Well some information about your computer might help. As well as the version of Windows. Freezing can be cause by a number of things, that is why it is hard to troubleshoot. Assuming your system is free of malware, heat is the typical cause. If you are overclocking, don't. What are your temperatures? Is the interior clean of heat trapping dust? Do all fans spin?

Its an older Presario but its still limping along til I can afford a new one. Im running Windows XP. Do you need the CPU model numbers or specifics? Also how to i check temp and is there a test for the fans? Sorry, a bit computer UN-savvy. So any help is appreciated.

Your last question is the easiest - you can look and listen to the fans to see if they are working. You should see the fans spin, hear the fan blades whirl, but not hear or feel the fan motor bearings rumble. And while at it, check for heat trapping dust.

If a PC Health or Hardware Monitoring program did not come with your computer, you can try Speedfan or Motherboard Monitor. Unfortunately, I have found that these programs often have problems properly identifying and labeling the sensor they are reading. The temperatures shown are as accurate as the inexpensive, low-tech sensors will allow, but it may say System Fan instead of CPU Fan. Fortunately, the programs do allow you to edit the labels, so I use Everest to verify the temperatures (as it is able to put sensor to label correctly), then edit the label in the monitoring program. In Everest, look under Computer > Sensor, then wait a couple seconds for the readings to appear. Unfortunately, Everest does not minimize to the system tray to show real-time temperatures, otherwise, you could use Everest instead of the others.

Have you scanned for malware?
