有關電腦既大問題..

我部電腦呢排唔知做咩..每一日我一開機..見到個windows開左之後冇耐..姐係msn個d彈完出黎..個主機會發出"嗶嗶聲"..之後個個mouse就會郁唔到..一係佢就唔發出任何聲都會冇啦啦個mouse郁唔到..我就算禁熄主機個制都冇反應..熄唔到機..要熄個大制先熄到..再唔係就自己同我自動重新開機..有一次連個windows都轉左做藍色版面..有篇咁既英文彈左出黎..
A problem has been detected and windows has been shut down to prevent damage to your computer.
If this is the first time you’ve seen this stop error screen, restart your computer. If this screen appears again, follow these steps:
Run a system diagnostic utility supplied by your hardware manufacturer. In particular, run a memory check, and check four faulty or mismatched memory try changing video adapters.
Disable or remove any newly installed hardware and drivers. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup options, and then select safe mode.
究竟發生咩事呀?日日個電腦都係咁..唉..唔該幫幫我..
