If your computer seems to be slow, read Slow Computer/Browser? Check here first; it may not be malware
. There are reasons for slowness besides malware - i.e. disk fragmentation, disk errors, corrupt system files, too many startup programs, unnecessary services running, not enough RAM, dirty hardware components, etc. As your system gets older it becomes filled with more files/programs and has a natural tendency to slow down so cleaning and regular maintenance is essential.Some Troubleshooting Tools you can try:
Download and run Motherboard Monitor 5
. If Motherboard Monitor's seems to be reporting high temperatures for your CPU check to see what your max CPU temp is from here
You can also use NextSensor
to check temperature and voltage or SpeedFan
to monitor voltages, fan speed, SMART status, and temperatures. SpeedFan can help you investigate the reasons for an unpredictable reboot or for a failing hard disk as well as whether you are likely to experience temperature related issues.
There are suggestions for troubleshooting power supply, video card, CPU, RAM, MB and hard drive here
You can use BurnInTest
to stress test the CPU, hard drives, RAM, CD-ROMs, CD burners, DVDs, sound cards, graphics, network connection, printers, video playback. This utility works on all Windows versions to include Vista (32-bit & 64-bit)
Another option is to use Microsoft's Online Crash Analysis
. The Windows Memory Diagnostic tests the RAM for errors with a comprehensive set of diagnostic memory tests or you can test your RAM with either of the following tools:
and follow the instructions to Diagnose with Memtest86+
.Once a bootable disk is made, just leave it in the drive and reboot your computer. However, before rebooting, you need to enter the BIOS setup and make sure that the Boot Order is set so that your first boot device is either the floppy drive or the CD-ROM drive, depending on which type of disk you made. If necessary, change the boot order, save your changes, and exit Setup. When the machine restarts it should boot from your Memtest disk, and the program will start automatically.
.Download ISO images for creating a bootable Memtest86 CD-ROM or an installable from Windows/DOS to create a bootable floppy disk or usb flash drive. Read the directions under Technical Info and allow Memtest86 to run through the entire battery of tests for at least 4 full passes (or let it run overnight). Any errors indicate that there is likely a problem with your physical memory (RAM).
