PC shuts down randomly

vbimport

#1

I have a PC with the following specs :

PII 333
256 RAM
4 HDDs
1 CDRW
1 DVD
MSI GF4 MX
SB Live
Raid Card
4 casing fans
1 PCI fan
300W MEC PSU

The problem is, my PC will turn off by itself randomly. I don’t think
my PC overheats because there are total 6 fans inside.The hardware and software are running fine. I can play games, surf net, etc.

I have done benchmarks and diagnose the hardware and found no problems. I just couldn’t think of any solution other the the PSU problem.

Do you think there is something wrong with the PSU ? Do I need to get a good branded PSU with higher power rating ? 450W ? How can I check my PSU ?

hmmmmmmm pc shutting down … well that could be alot of things … most of the time i have found it is heating problem but with yours sounds different …does it shut down at any specific time ? playing games ? or just about same time always ? does it just reboot or how does it shut down ???

sorry technician by trade and have to find out alittle more … i know one way i use to solve the age old heating problem …run it with side off pc … if stays on it is getting correct airflow …cause sometimes you have enough air inside but not going out …

Are you sure that your system isn’t affected by the Blaster worm?

If not, you might check the following things:

If you find anything interesting (low voltages on the PSU, excessive CPU temperature etc etc) report back!

I will download the memtest and prime95. I have motherboard monitor installed but no readings at all. My mobo doesn’t have temp. sensor.

My PC will turn of anytime, randomly. Sometimes after I have started it for less then 5 minutes. I don’t think it’s a heating problem. I have 2 fans for intake and 3+1 fans for taking out air.

My PC is not infected with the Blaster worm. I have firewall and security patch installed.

well it always helps to run panda antivirus online virus scan just to be sure it is not a virus … usually random boots are memory , motherboard , or procoessor …i did once have it be a hard drive …but that has only happen once in my experience …and then there is the heat problem woohoo …

I have a full system scan using NAV with the latest signature file.
No virus was detected.

Is there anyway to test the PSU? I suspect that’s the problem.
Maybe it’s overloaded.

no there is no way to test power supply …usually just go borrow friends
