MSI Mobo 915P/G Combo
XFX GeForce 6600 256 MB

A brief history of the computer

I bought it less than 2 months ago . Initial issues included SMP getting toasted ( probably due to the voltage problems in India ) and no sound. Both were resolved . THen I noticed the temperature being way too high . CPU temperature was averaging 70 degrees celsius . At the point the computer was crashing alot . I assumed its due to the temperature . Thus I got a new fan installed + a new 450 W SMP for the computer . I also purchased an APC 500 W UPS . The temperature certainly came down to the mid 50's which I think is acceptable ( Right ? ).

Remaining Problems

The computer is crashing alot . Usually it occurs when I click on any button , be it dial or a sign in. It occurs suddenly and the screen goes blank and the CPU emits beeps signalling a reboot.I disabled automatically rstart in the Startup and Recovery settings but the computer doesnt give any blue screen errors . I think its probably faulty RAM or the OS . Any ideas?

The second problem is very peculiar . THe computer starts propery goes past the loading screen etc and the desktop opens with the taskbar getting setup , all the desktop icons coming on screen etc , etc . Heres the catch - the computer locks up IF I dont move my mouse prior to it being totally readly .If I move my mouse , everything boots up normally and I use it ( until the next crash ) . If I dont , the computer completely locks up with the mouse and keyboard rendered dead .

I'd appreciate it if anyone could give me some good ideas on how to resolve this problem.

Regards.

 

50c is good for temp!!

The computer freezing and/or rebooting could be related to a driver issue!! Are all your drivers up to date??

It could also be a memory issue!!

I've attatched the file...MEMTEST 86+...this is a memory diagnostics tool.

Download it to your computer...unzip it...put a floppy in then double click on the floppy folder that was created when you unzipped it...then double click on "Install" and it will open a dos window...and ask you the target drive (which i'm assuming will be your A drive) and follow the instructions and it will make a bootable floppy. Then reboot witht the floppy in the drive (make sure the boot order in the bios will allow the floppy to boot before the drive that has the OS on it) it will then boot to the memtest program and start the diagnostics!! Let it run for a good 3 or 4 passes (hopefully without any errors) and see what it comes up with. Then when you are done simply remove the floppy and reboot the computer and let us know what it came up with!!
