Hi i have a few problems, my computer is turning off after a few seconds, sometimes it will get all the way to the bios screen before shutting off, leaving me no time to check anything. its very frusterating. Also before this started it was not getting anything on the screen (But not turning off)..

Two months ago i replaced the mobo because it wasnt getting anything on the screen and that fixed it. Now this problem is happening again and i want to find a way to prevent this.

And also 8 months ago i had to replace the PSU. i feel like there is something wrong or i am doing something wrong because i keep getting problems. I didnt build it myself but it is custom built.

Here is my specs

CPU: (Sckt775)Intel® Core™ 2 Duo E6600 CPU @ 2.4GHz 1066FSB 2x2MB L2 Cache EM64T

Try a new power supply. Disregard the fact you replaced it eight months ago, try a new one now.

You might also check the heatsink for the CPU. If it is not making a good connection, it will not cool properly and it will cause the system to shutdown.

could this possibly be caused by a virus?

Not if the system isn't getting as far as starting to load Windows.
Maybe a couple of decades or so ago, yes, when virii could live on floppy disks and most computers booted off floppy, but these days nobody uses floppy disks and bootable CDs with virii intentions are tantamount to what is essentially sabotage - you'd know about it, basically.

And as was said try replacing the power supply.... I don't know that brand of power supply but hi wattage numbers doesn't necessarily make it a good supply...
