Unpredictable Problem

I have a HP desktop with Pentium D. I also Upgraded it with a Graphics card of ASUS GeForce 6200. It was working fine until i installed a new harddrive SATA 250GB. After that it began to show sudddenly that monitor was sleeping and computer used to hang. It happens when any graphic intensive work is done. and after leaving it for some time it again works for few hours. i tried to check it by keeping the cabinet open but to no avail. got the graphics card checked but no problems there. after the problem starts the monitor sleeps in just five minutes if i restart again. computer is working fine if i take out the card and use the internal card with my motherboard. is the problem overheating or is it in the PCI slot.

T

The trouble is with PCI slot mostly.
it happened to me once.
long time back

most probably its PSU problem :wink:

, the HP PSU is not sufficient enough for powering a Gfx. Card & the 250GB HDD :wink:

HP comes with a PSU whose output is enough JUST for m/b & only one HDD. :wink:

i own HP Pavilion Desktop a1210in, its PSU's max. output is 250Watts.

check your PC's PSU, & try with a bit more powerful PSU.

& this HP cabinets is very small & has only one Fan (rear). so heat can be a problem too.

Change your SMPS or PSU. Same Problem with my computer when i had the following load with a 200W AT PSU/SMPS:

p3 500mhz
10gb+40gb
sony cdrw
hp cdrw
other motherboard loads(modem, sound, graphics, etc.)

After Changing the SMPS/PSU, my comp. became very fast!!!

any idead how much will it cost me? to buy a new psu. and of what level should i buy. cause i may also be upgrading my graphics card in near future.

and also why is it that it works fine for some time but when the problem starts then it re occurs without much even if i restart my compu.

^^^...dont buy PSU below 500-600w.

and what about the cost. any idea?

Browse through this forum. There are numerous threads on power supplies and their costs...

@shashanktyagi1 did you monitor the Temps.???

SMPS
Zebronics- 400 watts 24 PIN ( 915) = Rs.475/-
Zebronics - 360W Pure- Platinum Srs = Rs.1600/-
(prices @ Chennai)

you can go for either these or other brands like PowerSafe, VIP & if you got mo' money go for Antec, Corsair...

NOTE- Zebronics PSU's Fan makes lots of noise.

450W Rs.1850

my engineer gave me for the same price. it is not loacl

then what to buy. there is nothing else available. anyone from varanasi. tell some shop.

first experiment with any of your friend's PSU, to make sure the PSU is problem, coz still you havent mentioned the "TEMPARATURE" part.

you maybe facing a temp. related issue too :-|

also try this online "POWER CONSUMPTION CALCULATOR"

See if u can find iBall or Frontech.they r a tad better than Intex.i had a very bad xperience with Intex,had to send it for servicing 3 times in 2 months.My present iBall is performing OK.

Than most probably ur engineer has cheated you.Can you post the company name of the SMPS.

my frnds also have of same wattage. had the prob again so removed graphics card. now working fine. also my computer has become little slow after the second harddisk. temperature i swell below 40 always. mean 36-37, 67-68.
the online calci showing 380 watt needed. now will be buying from lucknow so please give exact price of any 500+ watt smpc. budget around 2000

ask Gx_Saurav for Lucknow shops & prices

for the slow system, check the HDD cables, coz you might have loosened them while removing Gfx. card :wink:

& if possible remove one of the HDD.

i dnt remember. i thnk it starts with 'V'

you can go for cooler master OR ZEBRONICS..

Zeb-500 is 1950/-

and clooremaster 500- is 2350/-

Go for the Antech models, may be u would have to stretch ur budget to get these PSU's but they are worth it. Even try upgrading ur graphics card drivers. Thanks......

graphic card drivers are updated. also tell any way to check my pci slot.
