On startup when opening windows my LCD monitor says no input signal and restarts my PC. I put a powermax.exe floppy into the floppy drive and did the advanced check on my HD and it passed. I changed the power supply, same problem. Oh, when I boot from the win xp CD it goes through the inital process where it stores settup information to RAM and then setup starting where it accesses the HD it sticks. Any suggestions please.

Download a harddrive diagnostic program from the manufacturer. They usually work by creating a bootfloppy that contains the testing prog. Boot with that and test your drive. I used to have a signature but it disappeared and I just couldn't be bothered writing another so please feel free to ingore this.

Richard59 Powermax is Maxtor's hard drive diagnostic utility. richjt said hard drive tests ok . richjt A monitor can't make the computer restart any way I know of. Something else caused that. Was this LCD monitor connected to this computer before and working, or did you just hook it up and it has not been working on this computer yet? Do you hear any beeps or other noises you don't normally hear? Have you been fiddling with or have you changed any connections or components or cards inside your case since the computer last worked properly, other than the PS? Are all the wires on the main connector from the second PS the same colors in the same positions as the original one? Does the fan on the original PS spin ok? Does the original PS stink (sniff at the fan outlet when off)? Is there a square 4 position or other special connector that also needs to be plugged into the mboard you're forgetting about? Does your video card require a power connector from the PS you're forgetting about? Does it have a fan on the main chip - if so does it spin when the computer is on? You could try removing the power to the case and making sure all connectors are all fully connected, and that cards and the ram are all the way down in their slots. Make sure the cpu fan and heatsink, especially right under the cpu fan, are free of mung. Is the cpu fan connected via 3 wires to the cpu fan pins on the mboard? Restore power and make sure the cpu fan is spinning properly. Have you had any problems with the CD drive you are using reading CDs before this, such as a bootable CD isn't always recognized? Have you tried using a laser lens cleaning cd in the cd drive? Is the XP CD a CD-R or CD-RW copy? Is it scratched? Have you tried cleaning it?

After it started to crash the moniyor failed, checked it with another computer then had to buy a new one. When it was working it had a DVD-RW drive as secondary Master and a CD-RW dive as the secondary slave. The two started to conflict with each other so I removed the driver for the CDS-RW and then the CD-RW, shortly after that it went into stop mode and then it wouldn't boot up , it kept saying no input sygnal and restarted. So I replaced the WD hard drive with a MAXTOR, processed it with a powermax.exe floppy, and then started with the win xp CD. It went through the setup is copying files OK and then on setup is starting windows it gets stuck, I waited for 2-20 minutes. ricardojt

To richard59 In aditipn to my previos response, with my old PS the PC was very loud. So I got a new one made sure all the conections went in the same places, the fan is working fine and the PC noise is a minor fraction of the loudnmess that it was. The CPU fan is working fine. Is it possible that I accidently unpluged one of the leads from the motherboard, although everyting I checked seems to be OK. The DVD-RW is fairly new but it may need a lense clean to make the CD start up completely anabling me to repair windows, or is it sticking because ot the no input signal problem. ricardojt

"After it started to crash the moniyor failed, checked it with another computer then had to buy a new one. " It is not clear at all in your posts whether you are getting a display in Windows itself since you changed monitors - it sounds like you aren't. If the old monitor was a CRT, and the new one is a LCD, your display settings in Windows may be set to something the CRT monitor could achieve, but the LCD cannot - e.g vertical refresh rate or resolution too high or not one the LCD can do. In that case, your LCD monitor should work when you boot from the Windows CD, and in Windows up until the time Windows starts to load, then it doesn't - you may get the no input signal displayed. However, that won't make your computer reboot. You can fix that situation by starting up in Safe mode and selecting Enable VGA Mode - the computer will start normally, but the video will be only a basic VGA. Install the monitor drivers that came with your LCD monitor - usually there is a Install or Setup program on the CD that came with it. If no Install or Setup program, go to Display - Settings - Advanced - Monitor and change the monitor Driver - Have Disk - point it to the CD that came with it and look for the *.inf file for your model. If the CD drive is not working or you have no drivers, select the Plug and Play Monitor setting, but be forewarned it may have some settings the LCD monitor can't do as well. Reboot normally - you should have video in Windows on the LCD monitor. "The two started to conflict with each other so I removed the driver for the CDS-RW and then the CD-RW, shortly after that it went into stop mode and then it wouldn't boot up , it kept saying no input sygnal and restarted." CD drives don't conflict with one another, unless possibly in the rare case one or both has defective circuits or is otherwise damaged. They don't need specific drivers - they are already built into Windows. Any drivers they have in addition to those have to do with the burner software or another program. By the sounds of it you had major data corruption on that drive, and that was probably the reason you had problems with them. Did you test the WD drive with a diagnostic utility? Windows can be corrupted yet the hard drive is fine. As I said above... "Does the fan on the original PS spin ok? Does the original PS stink (sniff at the fan outlet when off)?" The reason I asked that is if the original power supply was failing, it could have damaged anything connected to the mboard. If the original PS was noisy, it is likely the bearings on the PS fan are bad, and that can make the fan spin too slowly, or stop eventually, both of which can allow the PS to overheat and damage itself, and damage other components, including from the heat that is not being removed from the case. Floppy drives and CD drives are often among the first things to be damaged. Hard drives are tougher but the data on them can be corrupted. And a failing or faulty PS can certainly make the computer reboot for no apparent reason. Check both your power supplies, especially the old one. See response 4 in this: http://www.computing.net/hardware/w... It is possible that software problems or data corruption in Windows could make your computer reboot, but your computer should not freeze or reboot when you are accessing the CD drive with the Windows CD in it. If the contents of the CD loaded that far, it is unlikely the drive is faulty. You could however try using a laser lens cleaning CD on it, and make sure the CD is clean. If both CD drives are connected, have you tried the Windows CD in the other CD drive? On many computers, a bootable CD will work in whatever CD drive you put it in - if that's not the case with yours, change the boot order in the bios setup if each CD drive can be selected, or change the jumper on the drive if both drives are connected, so that which is master or slave is reversed.
