Hardware Malfunction

Hello!

Whenever I start my computer, a blue screen will appear and the I could see the following:

---------------------------
Hardware Malfunction

Parity Check/Memory Parity Error

The system has halted.
---------------------------

What does it mean? Also, whenever I start my computer an error message will load:

---------------------------
System Error in Bus/Device/Function 0000h
Parity Error in Bus/Device/Function 007Ah
Parity Error in Bus/Device/Function 007Ah
---------------------------

I tried System Restore already but it didn't work out. Also I tried Safe Mode but nothing happened. What should I do? :confused

 

See this Microsoft article: Hardware Malfunction Results in System Error Message. Did you replace or add memory to your computer before this happened?
