my pc keeps crashing

it started just over a week ago, i opened the case and gave it a good clean( there was alot of dust on the heatsink)

this semmed to have sorted it, then 4 days later it make a repetive sound and crashed when i restarted it the date was 2009

i have since purchased a new graphics card and it still seems to be doing the same thing

any one got any ideas

im running windows 7
intel quadcore q6600
6gb ram


forgot to mention before i was running xp64, i have since done a clean install of windows 7 as i thought it was a software issue
