probably itz either
minor case of software corruption/improper ground/cpu fan..
major case of faulty or defective main board/ram/daughter or addon card(s)..
..plz do check the following as in order:..
the Hardware part
if the ram(s) is loose/faulty..open clean/remove carbon & or oxide
formed on the teeth with an eraser n resit it..or replace with a standby
2) 4) a) see if ur hdd is noisy or emitting any 'ticking'

if so, u need either a fresh os installation or ur hdd is likely to b
3)remove/clean dust neatly..dust is non-uniform in
nature n may cause jam/short circuitry/excess resistance n many
more..resulting an increase in heat..
4) open the CPU Heat-Sink
with fan out of the socket..put some "Heat Sink Compound" (available in
local electronics chip level spare market) between the cpu/processor and
the CPU Heat Sink *** fan..resit/fit it tightly in position..
on main/mother board..see with a debug card for mb error..may b
short..look for defective capacitors(esp above1000mfd)/mosfets..go
through the mb's south bridge n the circuit lie around atx
connector..the crystal clock generator (if cpu isn't heating up)..
6) [in case of desktop] the smps itself may b defective/faulty..check the outputs of smps
viz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg
& grey~sb); -12v (blue); -5v(white); +3.3v(orange)..the 'oscillator and error amplifier ic', or
pwm switching regulator circuit..look for defective
check the battery [both main power & cmos], in case of laptops..
the Software part:..
hv a licensed and UPDATED antivirus installed (i
prefer avg/kaspersky, remember, without updation a full version antivirus
2) download, install n run microsoft kb890830..http://www.microsoft.com/downloads/details.aspx?FamilyId=AD724AE0-E72D-4F54-9AB3-75B8EB148356&displaylang=en

to remove, post me/us in ur comment with all the items listed in each
n every tabs herein)..
4) remove all unnecessary software from add/remove programs..
5) download, install n run 'Advanced System Care Pro'..http://download.cnet.com/Advanced-SystemCare-Pro/3000-2086_4-10399324.html
6)disable the following:..
'Automatically Restart' right click on my
computer->properties->advanced->startup n recovery->(uncheck
on the) Automatically Restart;
b)'Error Reporting' right click on
my computer->properties->advanced->error reporting->disable
error reporting->(uncheck on the) 'but notify me when critical
7) Increase the size of Virtual Memory, Initial: 1440; Maximum: 2880
if u r bot a professional, always better to seek advise from ur system admin/vendor....
