Can anyone help me with a problem that has just started on my system.It keeps switching it'self off. I have stripped it down to the bare minimum ie hard drive cd rom and vidieo card.i have reformated the hard drive but when i try to install win98se it gets as far checking the drive then switches off.Is it a powre supply problem or what the only thing I have not tried is a bios update but that is next on the list.
Thanks in advance

The BIOS is only suspect if you were hit by a virus that rewrites the BIOS.
Updating the BIOS will not correct this problem.

In fact, UNTIL you have the PC running stabily, DO NOT attempt to FLASH the BIOS. If the PC shuts down while you are flashing the BIOS, the motherboard may become totally unusable.

I would rank the power supply as a prime candidate.
Check and see if the cooling fan runs properly. Also verify that your CPU fan works properly.
If either fan is bad, the power supplyor CPU may need to be replaced also.

I have seen a few PCs recently, where the power supply control circuitry on the motherboard has gone bad.
If swapping the power supply and CPU does not correct the problem, it may be the motherboard itself.

Sounds like it is one of two things...a power issue or a heat related issue. Check both of these carefully and then doublecheck. If they are okay, then try replacing the ram.

Good luck! Hope this helps....
