Computer noise at startup

I bought this computer off an Ebay store where they assemble it for you. On cold mornings, it would make noise after turning on (power supply fan related). The noise would stop for a while. I got a replacement power supply (PSU) from the company and the noise stopped for a while. Now it's almost summer, it's not that cold, and the noise has started again. I'm thinking maybe it's not the PSU but maybe the flimsy case enters some resonant vibration? With the previous PSU I tried to buffer the spaces between the case and the PSU with tape, didn't do anything. With this new PSU, I tried to tighten the screws again, didn't do anything. I'm sure the noise isn't coming from the case fan, as, when I had the previous PSU, I disconnected that fan to make sure.

It keeps running forever.

My Windows 7 computer no longer turns off properly. If I shut the screen, it no longer sleeps or hibernates, it just freezes. If I go through the start menu to hibernate, it will do so, but the computer is still on -- the power and the wifi lights stay on, it's still running and using battery. This also happens if I go through the start menu to turn off the computer. If I hold on the power key, it will then turn off and restart or resume from hibernation normally when I turn it back on.

New power cord not exactly what I expected, should I return it?

My laptop power cord's ground prong (the third prong) broke off, and it stopped working in most wall plugs. I ordered a new one and when it came, it didn't have a third prong, but it works fine. Why is that? And more importantly, is there some future situation where I'm going to regret not replacing the old one with a new, three-prong plug? [more inside]

Ambien for my computer?

After a move, our computer (an older aOpen desktop) can't sleep through the night. It's fine if we leave it powered on, but if we put it to sleep, it seems to lose power sometime in the night and does not wake up properly in the morning. Will a cheap UPS (this one, for example) solve the problem? Any other ideas?

Computer turns on & off

There's a sick computer I'm trying to diagnose & I have no idea why it's doing what it's doing. It's a custom Intel-based desktop from maybe 3-5 years ago, can't easily read the mobo maker but if it's needed I can probably get it. When I hit the soft power switch it turns on briefly, the front power light comes on & the fan spins up then it all shuts down inside of half a second. Any ideas?

Converting foreign voltage desktop computer?

Moving a desktop computer internationally - we're moving from Korea (220 V) to Canada (110V). Is it as simple as removing the power "section" of the desktop and replacing it with 110 V at a computer repair place in Canada? Are internal components individually responsive to a particular voltage?

viagra for plugs

How do you secure a plug so that even if someone yanks on the chord, it doesn't come out of an outlet? It does need to be POSSIBLE to get the plug out sometimes, and it won't work to glue/staple the chord to the wall, because sometimes equipment needs to be moved to another room. [more inside]

Help me charge my G4 Powerbook

The power connector to my G4 Powerbook is almost dead. It only charges in one very specific position, and I have to twist it around for a few seconds to find the sweetspot (rotating it in situ). Nothing is loose and nothing is visibly wrong. I tried squeezing the metal sleeve slightly to make it more elliptical in the hope this would create a tighter connection, but it made no difference.

Seeking PC power supply recommendation

I am in the process of building an AMD Sempron 2400+ based file storage machine. I am seeking recommendation for how big a power supply I need. I am planning on 4 to 5 (may be 6 in future) 250GB Seagates, 2x320GB WD Sata drives, 1 DVD writer, Geforce FX 5500 video card. The $50 case has a stock 480W PSU. I am wondering if I need more juice and possibly something by a well known brand ? I recently built an Athlon box with Seasonic 430 PSU. Seems pretty quiet. Not sure if I should get another of those.

CPU power failure

I opened up my computer and tried to install RAM. After I installed the RAM, my computer would not come back on. I pressed the power button multiple times, and nothing. A friend checked to see if the power button was faulty and it wasn't. It's a Compaq Presario HP and when we plug the power cord in, the power supply just does this clicking. We're not sure what the problem is. I tried a new power cord and still no luck! Any ideas?

Should I keep an external hard drive permanently connected?

Hey, is it better to keep an external hard drive plugged into and constantly running, or is it safer (for archiving and the health of the drive, avoiding power failures that might otherwise zap an entire machine, etc) to only turn it on and connect it when you use it? Thanks as always for your thoughts.
