Please help me with this 'Dumping of physical memory'?

From past one week my pc was restarting automatically so I thought it was a virus issue and bought Norton antivirus and scanned the whole system. But still I鈥檓 having the same problem; it keeps restarting automatically and comes up with a blue screen stating 鈥楧umping of physical memory鈥? My friend told me that this happens if I have newly added hardware to my computer, but I have not done anything as such. I cross checked by

Right clicking 鈥楳y Computer鈥?

Then Manage

Then System Tools

But no new hardware was found.

Please help me out with this it鈥檚 so frustrating.

Thanks in advance.

Do a 'System Restore' to a point before the problem started.

I belive that the problem lies within the hardware that you already have. The problem could be one of many including the ram, any divices in your pci slots or a problem with the motherboard. I experienced the same problem with my computer and bought a new one but try replacing the things above and if worst comes to worst pay to have it fixed
It could be as simple as you are overloading your ram because you have too many programs running at once!
