Microsoft → [WIN7] Power outage then computer turned back on win 7 pro freezes

I can get to the desktop and can click on something then my mouse just does a circle as if working on something but I can't open any program. I can get to safemode and everything works there fine. I tried to delay any startup programs (not sure I got them all) to no avail.

Repair windows startup that ran twice did nothing though the second time it ran I could actually get in one program before the freeze. Restore two days ago did nothing to help. I uninstalled the only program downloaded in ages (chrome) with no help. mbam showed no problems. I haven't tried norton recovery tools since it seems like it would be unrelated. I also tried to scan disc/repair to no avail.

The only message received was originally... windows couldn't start yet it got me to the desktop. After that.. nothing.

This happened last year with a power outage and my computer all of a sudden began to work after a few hours...this time it is much longer then a few hours.

Suggestions? Ideas?

PS. I am using safemode with networking at the moment.

After a bad shutdown I've found drivers have been corrupted on the disk, and after checking for disk errors it had to be figured out what was broken. A real restore image is probably what you need at this point.

The system I worked on was able to get to a normal desktop, and we could reinstall the video drivers/etc, however files were still corrupted.

Somehow it is back. Makes me leery though of when/if it will happen again. Perhaps I'll get extra backup with alien respawn.. and get a power supply to warn when the power goes out and lets me turn off the computer normally.

PS I used »www.brightfort.com/spywa ··· ter.html backup image and got in..

Any computer I own has a UPS attached to it. In the end it could prevent problems like this and is worth it.

What is a good UPS?

APC and CyberPower are excellent brands.

Make sure the one you buy can even begin to handle your computer, and devices plugged in. They'll have two types of plugs, and I'd only have your computer and one monitor go on battery power. It won't last, and they plug into your computer via usb so they should trigger a shutdown. If it can't provide enough power to sustain them it won't do you any good.

They're also good for brown power, which causes power supplies to draw more, and when the power returns to normal can cause a spike in power to your hardware possibly causing damage.

Thanks!
I have a whole house surge protector.. not sure if brown outs would be an issue but neighborhood outages are the big problem!

How is one of these? »www.amazon.com/APC-BR150 ··· y+backup

With some of the high efficiency supplies, you may also need a UPS with true sine wave output instead of the stepped sine of most entry-level models, or even square wave of older or really cheap ones. I recently bought a Cyberpower 1000PFCLCD, which is one of the cheaper true sine UPS's.

Capacity wise, I think even small UPS's should run most any computer system. The advantage of higher power models is that they usually come with bigger batteries, which gives longer run time. Some more expensive UPS's even support adding external batteries.

Most UPS's have a UPS connection which can be used for monitoring. For basic use, you can just use the stock Windows setup, which treats it like a laptop battery. Using the manufacturers software can add features like monitoring the run time, setting certain options easily, etc...

Thanks.. just found out my dell does need the true sine wave. I am not interested in running anything long, just enough time to turn my computer off in a power outage.

Just ordered the cyberpower and thanks everyone for your help!

If you bought the one andyross suggested it's a good choice, even for gamers who need to have the bigger power supplies to support their gaming gpu.

There's others out there which are more suited for your average desktop with a smaller power supply like this one. What I do have to say about this model is the power button is more complicated than it seems at first, a read the manual moment.

good luck! personally, i use APC Back-UPS Pro 1500 (BR1500G), but i covet SUVTP10KF1B2S APC Smart-UPS VT 10kVA 208V w/1 Batt Mod Exp to 2, Start-Up 5X8, Int Maint Bypass, Parallel Capable

Spoke too soon I guess. I am back on safemode. Still trying to work out the problem.

As an aside, did find a problem with Norton... had to download an uninstaller and that and another start up repair may have fixed it.. just waiting.

First...hope you get your system sorted out soon...

I think you will be pleased with the CyberPower UPS you ordered. I have been quite pleased with my CyberPower CP1000PFCLCD. Your system probably has an Active PFC (power factor correction) PSU.

Prior to having my last system custom built 3 years ago, I had always use APC UPS's but I had read that the APC UPS I had wouldn't work properly with an Active PFC PSU. I contacted APC and they confirmed that my APC BR1000G was not recommended for Active PFC PSU's. APC recommended their SMC1000 UPS but it was very expensive--over $300--which wasn't in my budget. I rooted around online and found the CyberPower UPS's and bought the CP1000PFCLCD (note the "PFC" in the model name) for just a bit over $100.

While power outages are rare where I live, they do happen and I use CyberPower's Power Panel Personal Edition software to automatically (and gracefully) shut down my system when there is a power outage--the UPS is connected to my pc case via a USB cable (supplied by CyberPower). It's worked very well for me and I'd recommend CyberPower's PFC UPS's and their software.

I actually have 2 of the CP1000PFCLCD because when I had my current system custom built a few months ago, I ordered another CP1000PFCLCD for the new system--I'm keeping my old system as a back up and have it pluggeg into my first CP1000PFCLCD unit.

I just replaced the battery in my APC BR1500G Saturday.
