Hey pls..anyone help me over this....The cooling fan which cools the box where the power plug goes for the cpu doesn't start when i start the computer sometimes.I usually start it up by rotating it using a pencil !..There's one big problem too..I use Kaspersky Internet Security 2009.It doesn't start up now..i don't know...why!....My task manager shows 100% cpu usage and it's all gone to avp.exe(kaspersky)..while avp.exe has not at all been loaded up!.....My system seems to load things fast and i think it's becuse kaspersky isn't running....but apps like firefox and nero 9 takes lots of time loading up than usual and when i try loading CCleaner it doesn't start exept for puting an entry in the task manager.Also...the system sometimes doesn't light the red busy LED when it's actually busy!It all started up after i turned off the computer pressing the power button on the cpu thrice in a while due to power faliure and low UPS backup supply....Help me pls...!! I beg u!!

No need to blush - I keep a wooden popsicle stick handy for just such things. But still, it means the bearings are going bad in the PSU fan and I think you need to start there. PSU fans can be replaced, but since there are deadly voltages inside a PSU, that should be left up to a qualified technician. Once you add the cost of a new fan, plus labor, you probably should just consider getting a new power supply anyway. Judging from your other HW symptoms, your current supply may be having other problems, perhaps caused by overheating due a failing fan. A bad supply can take out everything plugged into it. Not worth the risk to keep using that supply, at least not without getting it properly tested. See my canned text below in choosing a new supply.

That said, it seems you have several other issues, including possible malware. How long have you been running without your antimalware program running? If this were me, while waiting for my new supply, I would pull your hard drive and install it as a secondary drive (not boot drive), or in a drive enclosure and attach it to another computer, then scan it thoroughly with that computer.

Use the eXtreme PSU Calculator Lite to determine your power supply unit (PSU) requirements. Plug in all the hardware you think you might have in 2 or 3 years (extra drives, bigger or 2nd video card, more RAM, etc.). Be sure to read and heed the notes at the bottom of the page. I recommend setting Capacitor Aging to 30%, and if you participate in distributive computing projects (e.g. BOINC or Folding@Home), I recommend setting TDP to 100%. Research your video card and pay particular attention to the power supply requirements for your card listed on your video card maker's website. If not listed, check a comparable card (same graphics engine and RAM) from a different maker. The key specifications, in order of importance are:

• Current (amperage or amps) on the +12V rail,
• Efficiency,
• Total wattage.

Then look for power supply brands listed under the "Good" column of PC Mechanic's PSU Reference List. Ensure the supplied amperage on the +12V rails of your chosen PSU meets the requirements of your video card. Don't try to save a few dollars by getting a cheap supply. Digital electronics, including CPUs, RAM, and today's advanced graphics cards, need clean, stable power. A good, well chosen supply will provide years of service and upgrade wiggle room. I strongly recommend you pick a supply with an efficiency rating equal to, or greater than 80%. Look for the 80 Plus - EnergyStar Compliant label. And don't forget to budget for replacement UPS batteries, or a new UPS with AVR (automatic voltage regulation).
