PC keeps crashing and restarting

[atticus9288]

I have been having this problem where my PC crashes at random times for about a month now, ive tried everything to fix it from reinstalling windows, new memory,new motherboard and removing graphics card. After all this the problem still persist at random times. My PC isent overheating i am monitoring the temps and its staying cool. the computer worked great for 5 months after i built it, then Firefox started randomly crashing on me one day and that when the problem started, What could be causing this? could my CPU have gone bad?

What are you doing when it crashes ?

What does Windows' minidump file (created at each crash) blame?

Update the BIOS. Our company has had issues with M4A series Asus boards and Memory compatibility resulting in BSODs and random restarts.

I will try updating bios

Updated bios but on restart it seemed like it was about to crash. Start up are getting extremely slow compared to how fast it was a month ago

A few things to try:

• Swap or test the PSU, regardless of what brand or how old it is.
• Check the CPU, chipset and VGA temps.
• Check the capacitors on the mainboard and on any add-on cards to see if any are leaking or bulging.
• Test the RAM with Memtest86+. It's possible that either the RAM or the motherboard RAM slots are faulty.
• Test the hard drive with the manufacturer's drive diagnostics utility.
• Remove any add-on cards and strip it down as much as possible and see if it still crashes

Psu is good, temps are fine, board is good, ran memtest it dient find anything, all cards are removed,hard dive is good
