Is leaving my computer running for a long time dangerous?

Hello, recently i found myself leaving my computer running for a pretty long time , recently i've left it running for like 3 days , and i am worried it will blow up or fry itself or something, here are the specs...
CPU: Inter core 2 Quad 8400
Mainboard: Gigabyte mainboard
Memory: 3072mb DDR2
GPU: NVIDIA GeForce GTS 250

I really need to leave my computer on for the night (For stuff like going on Megaman x8, selecting noah's park, and then place a heavy object on the LEFT button to get lots of metals from the metal generator!) and other things, but i can live without that if my computer is in danger.

Yes every minute you leave your computer on over 12 hours increases its chance by 5% to randomly explode.

lol, as the previous two posters have taken care of the funny comments, I'll give you a serious one... I have not turned off my PC for the last 3-4 months, it has yet to implode (or explode for that matter).mfp16

Besides running the components down (which happens any time a pc is on) and as long as everything is in good condition nothing should happen for leaving you computer on for long periods of time.

aside from wasting electricity and running up your bill, there are no dangerous effects. parts may wear out but that's to be expected and adds a neglible difference.

The PC might not explode but your wallet sure as hell will

Yes, it's completely on... no sleep mode, I do have the monitor turn off automatically though. I've been leaving my computer on pretty much non-stop with the occasional reboot or a day or two of downtime for the past 5 or 6 years, it's fine...

My computer hasn't been off since I went on vacation about 4 months ago.

I leave my computers on nonstop for years. No problems yet.

It should be fine though you run the risk of it becoming sentient and murdering you in your sleep.markop2003

I left my PC on for 6 months straight, only powering it down when I left for more than a day.

Apart from the obvious wear to parts your computer should not blow up. However I thought leaving computers on for long periods of time can cause the OS to become more unstable. Something about reacurring errors piling up...

For fun i left my second computer on for a 9 months straight...

Why would you not turn your PC off, unless your downloading something really big its just wasteful.

I had my old PC on for 7-8 moths and then I had to buy a new PSU xD

If servers can take a beating in tight racks than Im sure yours can with a ventilated system. Thats the best comparison I can think of.
