Re: moniter problems

Hi, have you used the same motherboard in the two towers? sounds to me like you may have a couple of faulty capacitors on the board. Open the case and study the capacitors closely [with a magnifying glass if need be] capacitors fail very often when heated. they are the round components that sit in sets of 5, 6, or more in a row on the board. if any are bulging from the top or bottom, then its time for a new board. Regards mistyman

Power went out and i olny have a red light on my lg tower and an orange light on my moniter

That is extremely vague.. but I'm placing my bets on if it's not running you have a short in the power supply. If it is running, then you need to test your power going in (you can get a voltage testing module from BestBuy) make sure you have voltage going to the mother board. if it's not correct then you have a bad Powersupply and it will need to be replaced.

Fans on Mac Intel Tower

I would suspect it needs a good internal cleaning. The accumulated dust will cause the computer to overheat. Disconnect all cables and take the unit to a place where you can clean it. Remove the side panel and then with a can of compressed air or an air compressor blow all dust out of the unit. Pay special attention to the heat sink on the processor. Make sure you clean the power supply fan. Be sure and not touch any internal components without first grounding yourself to the chassis. It is best to do this outside as the dust will fly everywhere. You should clean the inside at least once a year. Merry Christmas.

How do you know the graphic card is working if you can't get a picture?
Sorry to be basic about this, but you really need to go back and check your connections again.
Do you have another Mac? You can boot the Mac Pro into target disk mode, then boot the other Mac off its disk using a FireWire cable. Then you can set up Apple Remote Management and enable VNC logins on that machine; then shut everything down and reboot the Mac Pro of its own drive. From the other Mac, use Chicken of the VNC to remotely view the Mac Pro's "screen" (I assume existence of an ethernet network here). Now you can run any tool on that Mac from the other Mac -- visit the Displays panel, look at System Profiler, etc., just as you would if the hardware display were working.

My computer got some serious problem, its an AMD tower computer. Yesterday, i powered my computer then at once : the CD-rom wasnt working, the monitor didnt work (No Signal) and the computer didnt boot -...

The problem is one of the two following. Either the motherboard is faulty, or the RAM is not seated properly. Try re-seating the memory, and, if possible, just use one memory stick. If that doesn't work, than you most likely have a faulty motherboard, or faulty RAM - the same symptoms apply. I have seen this before and this is always the case from my experience. I would try to return it or work something out with the seller somehow. Hope this helps!

XP-Pro Crash

I don't know why but some systems which have XP (SP1 or SP2) simply can't take the upgrade to SP3. Your system appears to be one of them. For instance our family's computer had XP SP2 and upon upgrading to SP3 we received a fatal crash while XP was loading into normal operating mode.

I managed to resolve the issue by booting to safe mode and restoring the system to a date before I installed SP3. Sorry that the new SP doesn't work for you.

I have intel pentium 3 with 128 ram. how can i increase ram memor

To upgrade your RAM you would need to know what type of RAM your motherboard supports. Once you have this info you can then check online who sells the RAM modules. Once you make your purchase you then can remove the old modules, replace with the new modules & reboot. Hope this helps & please remember to rate my answer. Thanks.

Upgrade GX150 from P3 933mhz to something better

yes, to 1.1 gigs is not difficult, much higher than that and you would have to upgrade the BIOS software.

Id your motherboard also has onboard video, and you have a graphics card, make sure that you try both connections. Chances are if you are using a graphics card and your computer thinks your using onboard, then you will get the no signal or vise versa.
