Random turn offs...

[Hobbie3321]

dunno how to describe this, but.. ok 2 days ago i installed windows after i spent my 6 hours building my PC... everything went hunkey dorey... yea anywho yesterday(and today) whenever i try use the computer for more than say... about 40 minutes the computer goes FUBAR and shuts off, not turns off now...just shuts off for half a second, and then it turns right back on and well... reloads everything (basically like a split second reboot i guess...without the saving of work)

i dunno if its virus inflicted (Behind a Router BTW), or windows...or the PSU...but here

the RAM is a Corsair XMS 2gigs (2-3-3-6)
the Harddrive is a Western Digital 16mb cache, 250 gigs
CPU is the AMD 4200+ Athlon 64x2
MOBO is an A8N-E
PSU is a Antec 500W smartpower 2.0
Graphics card is a *Hitech* Radeon X800GTO x16 PCI:E
the CD-DVD thingy is a Liteon combo thing...
the Floppy, is something i stole from my other computer
OS is Win XP Pro btw...

any help would be nice also the crashes happen when im not doing anything (well i was always talking to my friends over Trillian and downloading the WoW patches) and my little monitor says everything was in the green... Temp was about 33-35 Deg C and... etc etc

What you're getting with an instant restart, is actually a blue screen - windows automatically bypasses this and restarts.

To get a blue screen, with an error code, go into the properties of 'My Computer' with a right click, head over to the 'advanced' tab, anc select 'properties' of 'system startup and recovery'. Once there, untick the box entitled 'automatically restart'.

If and when you get your next bluescreen, post back with what it says.
