Power Save Mode problem!

Hello all, basically I have another computer now, given to my brother by his friend, so yesterday I turned it on and it was working, image on monitor and everything. Oh and btw windows isn't installed yet as I'm gonna reinstall it because there is some problem. SO yeah the writing and everything appears on monitor. So now today I was going to install windows but guess what, I turn on the PC and there is no image on monitor. I press the buttons on the bottom of monitor and it brings up Power save mode press keyboard or move mouse, I do this but still nothing comes on screen. So I am trying to figure out what problem is, oh and also yesterday I did open up case and have a look at my new well used PC but im sure this has nothing to do with the problem.
Any suggestions/help would be greatly appreciated!

If it appears to be 'stuck' in a power save mode, hold down the power button for 8-10seconds and that should power it off, then unplug the power cord (if it's a laptop, remove the battery too). You can also use the main power switch on the power supply on the back of the tower (however, not all PCs have a switch on the power supply). Let it sit like that for a few minutes, then plug in and power up. Then go to the BIOS and look for the power settings and change them to suit your needs. Once Windows is installed, you can change those power settings too. Personally, I'd recommend disabling 'Hibernation' mainly because of the problems I've seen caused by it. Besides, it takes almost as long to come out of hibernation as it does to power up and boot to the desktop, so I see no reason why someone would use hibernation over simply powering off...

EDIT- I just re-read your post, and it appears that the 'Power Save Mode' message you're getting is coming from the monitor and NOT from the PC. Anyway, try the things I posted above and see if that works. If not, unplug the power cord from the PC, open the case and make sure that nothing came loose while you were in there. Double check all data and power cables and be sure they are firmly seated. Then check all the add-on cards and memory sticks and be sure they are firmly seated and completely inserted in their slots. Check the back of the PC and make sure the monitor, keyboard, and mouse are all completely plugged in. Then plug in the power cord and power up. Let us know how it goes!
:-D

 

You seem to have misunderstood, firstly it's a PC and secondly no need to power it off as what I mean is yesterday the montior was working but today nothing is showing up on monitor

Edit: It can't be the monitor as I have tried my other PC with the monitor and it works fine

 

:-o I guess I did misunderstand. So- the PC produces no video, but it worked yesterday, and the same monitor on a different PC works fine. Right? So- does the PC power on? Do the LEDs light up, and the fans spin, but no video? Or does absolutely nothing happen when you push the power button? If the PC turns on, but no video, then the video card has likely gone out (or the on-board video chip has failed). But this can also be caused by bad memory, bad CPU, bad hard drive, bad power supply, just about anything can cause a PC to have no video even when it powers on, but the most common is a failing video card/chip. If the PC doesn't even power on, then it's likely to be the power supply. Luckily, replacing a power supply is fairly easy, and inexpensive. You can purchase a good, basic power supply for under $50.00 at your local PC store or online. If you have a higher end video card, then you'll need a better power supply. If you need advice on a new PSU purchase, post the PC specs (make, model, RAM, CPU, HD, CD/DVD, video, etc) and we'll do our best. If you just have a basic system with on-board video, a brand name unit in the 400w range should be fine. Try to borrow a friend's extra power supply if possible (if you don't have an extra yourself) before buying a new one so you can be sure that the problem is indeed with the power supply..... good luck! Keep us posted, and I'm sorry for the misunderstanding on my part LOL

This still applies ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^

 

THanks for info, to answer your questions yes the lights turn on, fans spin ect, btw only one of the ligh turns on and that is the one with like sun and rays around it the other light which is like a drink glass test tube doesn't turn on. Also I checked inside and everything is secure but there were two of those pin connector things not connected, there are 2 of them and they are 1pin each and labelled 1gnd and 2gnd, also I saw another 9 pin connector i think it was unplugged, that was labelled aux, but i'm sure this isn't related to the problem.

 

This is the power indicator; the other LED is the hard drive activity light. Since the PC does power up, but gets no video, we'd check the video card. If you have an 'add-on' video card (vs. on-board video), carefully remove it from its slot, check that the heat sink and fan on it are clean, then carefully and firmly re-seat it and secure it. Some video cards have power connectors, so be sure that it's connected. If you have on-board video and you're using an add-on video card, remove the card and plug the monitor into the on-board video connector on the back of the PC and see if that works. Memory sticks: carefully remove them from their slots, then carefully and firmly re-seat 'em, making sure they clip in all the way. You may want to do one stick at a time and power up after installing each stick to see if one was responsible for the problem. If you have any extra add-on cards that aren't required for the system to boot up (this would be just about any other card in the PC like a sound card, modem, ethernet card, TV card, etc) remove 'em temporarily. I have also seen faulty floppy drives cause a PC to not boot up correctly, so unplug the data and power cables from your floppy drive (if you have one) and see if that makes a difference. You can also do the same for your CD/DVD drives as they are not required for the PC to load to Windows. The only things mandatory for a PC to boot up are: processor, memory, hard drive, video card or on-board video, power supply, and of course, a functioning motherboard. Technically speaking, even the keyboard and mouse aren't required, but you should at least leave the keyboard plugged in. Also, if you could please post the make/model of the PC and/or the motherboard, it could prove to be very helpful.
Good luck!!!
:-D

(be absolutely certain to unplug the main power cord from the rear of the PC each and every time you get in there and start plugging/unplugging components, cards, and memory sticks; even though the PC is turned off, many motherboards stay "hot" when the power cord is plugged in, and there's a small amount of 'standby' voltage running through the board; it's enough to cause serious damage to system components)

 

thanks for your support but problem is sorted now

Think it's one of the memory sticks tho ima place it back and see if it was the problem or just re placing everything could of sorted the problem out.
Oh btw im on that computer now:cool
