Dodgy voltages

[mrbad]

PCAlert4 (a monitoring program) says under 3.3V where the value should be somewhere between 2.5 and 4.5V that I have 1.49V. I know that this cant be a good thing as it is flashing in red writing. Could someone give me an idea as to what this means. From time to time i experience random crashes and I think that it could have something to do with my voltage problem.

I would be very grateful if anyone could help me in any way.

download a program called Everst or Hmonitor and confirm the voltage reading first. 3.3V rail is used mostly by the CPU so 1.49V is not good. I would recommend confirming this reading ASAP and if it is true turn off the PC until you replace the PSU.

Thanks for quick reply, I downloaded the programs that you recommended and Everest says that my 3.3V is at 3.3 and the AGP value reads 1.49V instead.
Hmonitor says its my I/O that is 1.49V. It also highlights my core voltage in red which is at 1.66V.
I shall try sticking in a different PSU sometime when I have time to see if that solves my problem.
