Yes thats right begging. Ok, so I'm stationed overseas and about a year ago I decided to try to build a computer....and it worked. But then about a month ago I went to turn it on and it just didn't start. Everything powered up but it didn't boot up. So I restarted it and still nothing worked. This went on for about 20 minutes then BAM, it started working, like nothing was ever wrong with it. When I try to go to the BIOS menu it brings up a different one with only 3 selections but pressing the respective key doesn't do anything. So I bought another mobo and it doesn't work either. So I don't know where to start next. Can anyone here help me?

My system:
3.0Ghz P4 800FSB
Gigabyte mobo
500w true blue antec psu
1Gb kingston ram
Radeon 9800 Pro graphics card
audigy 2 sound card
WD 20Gb hdd (master)
WD 250Gb hdd
Plextor DVD-burner (master)
mitsumi 16x DVD drive (slave)
cooler master wave master case

Note: I'm using a 220v-110v converter/transformer.

Any help is greatly appreciated.

I'm thinking virus...

No, I don't think so, I'm like the only person in the world without internet at home (2 euro a minute is too much) plus I had the IT dept. scan my computer last month when the problem first started. I'm worried it's the processor is screwin up (just a gut feeling).

could it have been over heatin

could be...it was running hotter than it should have. I never over clocked it and i used thermal paste, had a thermaltake copper heatsink/fan, and 6 case fans but it still ran at about 150 degrees F. But if it's fried, would it still work occasionally?

No it wont fry. P4's have a thermal sensors built into the chip. When it starts to overheat it will underclock its self until it stops overheating. So your p4 3.0ghz can in theroy underclock its self to a p4 100mhz proc so it wont overheat.
