Hi wonder if you can help.
My PC has some unusual problems; it has started to randomly crash (under load, ie gaming etc). When it crashes it just switches off, no warning, no error message, no hang, just literally switches off. I cannot switch it back on until i flick the power switch on the PSU off and then on again. After the third crash the PC came back on, but would not recognise any USB devices(ie mouse, printer, removable storage); BUS powered devices still get power but it seems that the OS cannot see them. When returning to windows the is no "the system has recovered from a serious error etc, message. Please help this is my main system with all my work etc on it, and i am really worried.
AMD x2 4400
2 gig corsair XMS
2x 36g raptor (boot)
3x320g WD (raid 3 array on XFX raid PCI card) Storage
Nvidia 7800gs GFXcard AGP
tagan 800W PSU
2x pioneer 109 DVDRW
CPU is at 50 C in the Bios, this machine is not and has never been overclocked.
Hope you can help and thanks in advance
