computer has decided not to boot up

everything was working except for the fact that my computer was intermittently overheating and shutting down. So i decided to clean all the dust and what not out of it. However after doing so it refuses to boot up, it starts for about 5 seconds and then shuts down again. I dont know whether this is because of a mistake on my part as i have cleaned it many times before.

Any help would be much appreciated.

My hardware specs are as follows:
-Intel Pentium D 3.0Ghz
-Ati X1800XL
-250gb maxtor HD

(cant think of any other parts that could b relevant but if required please let me know)

overheating & shutting down

In reply to: computer has decided not to boot up

I'm no computer wiz, however I had the exact same problem. My friend told me to replace the "Power Supply" with at least a 300watt(I had a 100watt). Did it myself, very easy, problem solved.

Verify and inspect

You may have caught it in in final death throes, the PSU finally gave out, replace with a better wattage unit. -OR- during your cleaning you unseated, unsettled some cabling, etc., reseat all cables and verify the work and try again to power-ON. If it still fails, then swapping or replacing the PSU is a logical step. However, it could be possible 2ndary heat stressed components also gave up the ghost, thus inspect and/or swap out to another test bed if possible.
