yes, depends on what the error code is, if it suddenly pops up,
possible causes :
1) your Operating System is corrupted.
2) some virus/spyware thing is making your comp crash
3) hardware error, PCI card related.
4) CPU (overheat)
5) Ram faulty
6) mainboard faulty/unstable
7) cheapo/faulty power supply making mainboard unstable or even both.
8) hard disk faulty
solutions :
1) reinstall windows
2) reinstall windows.
3) take out all PCI cards. see if it still crashes. put them back one by one to ensure working condition
4) go BIOS check cpu temperature. check see if cables are stuck in your cpu fan screwing up cooling process. try replace cpu with a friend's temporarily to test.
5) if it's kingston lifetime warranty, bring to www,convergent.com.sg albert complex.
6 & 7) to be honest this is one of the hardest. sometimes mainboard appears to be working fine and it's the power supply problem, by the time you replaced the power supply with a good one, the cheap one has already damaged the old one. happened to me before.
8) , run a diagnostic check such as western digital's. watch out (Hear) for weird noises and abnormal high temperatures.
welcome to my world for the past 10 years.
