+ 0 Votes Hardware Issue TheChas 7 years ago From what you have done, this almost has to be a hardware issue. However, since you have done multiple clean installs, make SURE that you have all of the correct device drivers installed. Most critical are the drivers for the chip-set on the motherboard, video card, and network adapters and modems. Then, if you are certain that the drives and memory are fine, then the suspects are the power supply and the motherboard / CPU itself. Check your CPU fan, it MUST spin easily by hand. Take a close look at the capacitors near the CPU socket. (round cylindrical parts with silver colored tops) If there is any evidence of bulging or liquid leaking from them, you need to replace your motherboard. If the motherboard looks good, I normally start with the power supply. Both because it is easy to change, and cheaper than the other hardware. Plus, I have had a run of bad supplies lately. If it is not the power supply, carefully remove and reseat your RAM modules and plug in cards. Chas + 0 Votes replty to Chas jmg0033 7 years ago nice one will try a new motherboard and let you know.
