Computers

PC Trouble

So I finally broke down and bought a new PC, to replace my 5-year old 600MHz P3 system. It's great to have a new bleeding edge computer, but I'm having a strange problem with it that I thought I'd write about, in hopes someone will find this on a search and have some information for me. This system was built by a co-worker friend who is very experienced with these things, and we are both baffled by this issue.

The deal is, the system shuts down when the CPU gets above 62C, even when the BIOS shutdown temp is set to 80C. I set it to 70C, and still, it shuts down at 62C. I can get it to this temperature by running a CPU burn-in utility. The interesting thing is when I disable the BIOS overtemp shutdown, it no longer shuts off. So it's clearly the BIOS that is shutting it down, but apparently way too soon. I'm using an Intel P4 Prescott, and I know they run hotter than any other CPU out there, but that's not the issue. Here's my system specs:

Intel P4 Prescott 3.4GHz
nVidia GeForce FX5500 128Mb AGP 8x Video
1Gb RAM, single DDR400 184-pin DIMM module
575W Dual fan Power supply
Biostar P4M80-M7 motherboard
800M MHZ FSB
10/100 on-board Ethernet, Realtek RTL8100C
Audio: Realtek ALC655 6-ch AC97 codec
USB 2.0, 8 ports
HDD: Maxtor 250Gb IDE, ATA-133

Anyone who has information about this, please drop me an e-mail or leave a comment. I've gotten a reply from Biostar, the motherboard maker, that basically said to run with the shutdown disabled, because it runs fine that way. Well, my smoke detectors run fine when they're unplugged too, but I'd rather they run fine while plugged in.

Another issue for the search engines out there: I found some kind of apparent virus that takes 50-60% of my CPU, and it's a program called akypcofz.exe - it showed up one day, and I tried to kill it with the task mgr, but it restarted almost immediately. I deleted it's startup entry in the registry, and that did it, but a few days later it showed up again. I killed it again and it hasn't returned for a week, but I'd like to know what it is and how to be rid of it for good. It doesn't seem to show up on any searches, so I'm putting it out here for someone to discover. Here it is again: akypcofz.exe akypcofz.exe akypcofz.exe !! I have a copy of the file if anyone is interested in analyzing it.

You might check to see if there's a difference in temperature readings,i.e., Fahrenheit vs Centigrade, on the governing controls.
