Hi guys

My PC freezes on random events specially while i play video or songs or brose net. i had experienced this problem before and solved it (full goes to "techsupportforum") by taking off one of my ram from the motherboard slot( i had 3 RAMs) now, no matter how many ram i install or take off, it freezes, and two thing i've noticed :

1. when in freezes it also turns off the usb power supply because it turns of optical mouse bottom light and keyboard numlock and other lights etc.

2. when i run vista or win7 the frequency of freezing is higher than running the system on winxp.

i've gone through the memory test using "www.memtest.org"

i'm giving my pc requirement:

OS Windows XP Professional Service Pack 3(present)
Processor Intel Core 2 duo E8400 3.00 Ghz
RAM 2x A-data (1gb,800fsb) and 1x Transcend (1gb, 800fsb)
Graphics card Asus NVIDIA GeForce 9500gt
Sound card realtek high definition audio
network adapter Realtek RTL8168C
PSU EZCOOL ATX600 (600w)
with three extra cooling fan running

please help me guys !!!!

First possible issue I see is the EZCool PSU. They are not good quality.
Second is mixing RAM brands.
Third is the A-Data RAM.
Remove the 1GB Transcend stick and see how it goes.
Brand & Model of the Mobo?

Confused

Hi guys.

I've bought a CoolerMaster extreme+ 650w PSU, 1 "WD Caviar Green 1 TB SATA Hard Drives (54000rpm). but still having the problem, i also tried removing 1tb transcend ram and then other combination still the same problem, i did "memtest" diagnosing tool and it couldn't found any error in any of my RAMs, whether i use mother board inbuilt VGA card or i use my ASUS nVIDIA en9500gt graphics card.... same issue..... it freezes in random time....... only thing i haven't tested is my motherboard....... but since i don't have a extra MB...... what do you think guys it the problem with the MB???

one more thing, i recently installed Win7 and now if i try to load a 3d game ( like Pro Evolution Soccer 2010) PC freezes within few second, where my pc never freezed wihile i was playing 3d games in xp with this freezing problem!!!

any kind of response would be appreciated.

the CoolerMaster extreme+ 650w PSU is low quality

your 12v line is down

this

puts out more power than the one you have

My System


coolermaster make good cases, they PSUs are ok but not great.

As said you 12v line is low and that is the most important line.

Seasonic,corsair,OCz extreme,CWT,PC power and cooling and thermaltake tough power units are good power supplies.
