Vista random shut down
My computer, a HP a6030n with Vista home premium 32 bit OS has been shuting down randomly in the last couple of days. My Tend Micro Antivirus shows no virus and just did a memory check and no errors. I have not had this happen while on the computer so not sure if there is a error report or not. Happened twice today. Let me know what you need and I will get it if possible. All help will be greatly appreciated.

hi the problem could be your power supply try taking the side of the case and see if you can read the label or at least get the wattage

Sorry have not had time to pull off case and check power supply yet but have set up event logs and looks like I have to many process's running. Took a look at them not sure what some are and here are some examples of the event log.
ntoskrnl.exe is doing excessive disk activity
many processes are using to much memory
rundll32.exe is doing excessive disk activity
explorer.exe is doing excessive disk activity
ntoskrnl.exe is doing excessive disk activity
photoscreensaver.scr is doing excessive disk activity
I have run spysweeper and trend antivirus over night with nothing.
I will look at the power supply now and re-post later.

Thanks

Ok took the side off the case and here is what i found. 3 fans all running, the power supply is HIPRO and the model number is D3057F3R. I did not write down the wattage as there were 3 of 4 different ratings and i was not sure which one was relevant, Case was relatively clean but did vac out the dust as best I could. Let me know what is next. Oh almost forgot, right now i have 2 App running IE7 and sysconfig and have 76 processes CPU is bouncing between 5 and 25% and memory is 36%.

hi it is quite likely the power supply is not able to supply enough power and is being over taxed and shutting down

Exclamation Rare, but possible
There have been RARE accounts where the firewall/anti-virus will not report any problems, yet shut down the computer because of a "viscious attack." This has happened to me with an old version of McAffe, I just shut off the firewall and it was all good.

As a test, boot to safe mode.

If the problem happens in safe mode, it can be caused by ONLY;
1. hardware;
2. malware;
3. corrupt Windows OS:
4. corrupt registry.

I would be on joeten's # 10 analysis.

Could be your fans, CPU specifically, is not spinning enough to cool the CPU.

Is your NVIDIA GForce 6150SE nForce 430 standard or add on? If add on, joeten's probability increases to > 95%.

You are probably using an add in video card, because your PC, per HP has a video chip built into the motherboard.

So do I replace the power supply? and also is there an easy way to check out the proccesses that are running or is 73-77 processes normal. I set up an event log and a lot of the warnings are from to many processes.Like right now I have IE running and task manager and there are 77 processes, CPU usage is at 6-16% and Physical Memory is at 54%. Is this normal?
Thanks for everyone help.

Suggestions on a power supply. Also I did an driver upgrade on the NIVIDIA video card, what happens to the old driver? is it still on my hard drive? If so how do I find it and should I delete it?
