Computer starting trouble

[sumeet71]

My Pc a dual core 1.8 with 512 ram has developed a bajaj scooter problem. It starts only when laid on its side. Sometimes it wont start altogether. On opening the cabinet the times it doesnt start with the power on button the fan attempts to move but stops . I have got the fan checked and also the motherboard. they work fine alone what could be the problem.

Clean your System RAM and check Hard Disk. Maybe this is the case of faulty/losse connection. Do check SMPS also

look dear it can b associated with a bunch of problems..
i suggest u to first check ur HDD if cable is well connected ...
secondly this may also cause due to improper cooling of processor by sink/fan..
thirdly re insert RAM..
lets see if it works!!
