I have an ECS K7S5A SiS? 735 SOCKET A Motherboard, CHIEFTECH Server Chasis (Workstation Tower) Model CT1030 - Black with AMD Approved Power Supply (Enhance 300Watt (P4) Model# ENP-0730), ATI OEM Radeon 7500 64MB DDR AGP with DVI/TV/CRT-OEM, AMD Athlon 1700+XP.
Now on to the problem: When I turn on my computer, the screen stays blank for some reason. I have tested the gfx card with another computer and the same monitor, and it works fine. But maybe it is a compatability problem. I think itmight be a faulty AGP slot on the mobo. Has anyone had a similar problem, or knows how to remedy my predicament? Please help. I'm wagering all of my points, if that matters to anyone.

One check the memory to make sure that it is secure in slots
Try downloading the latest drivers for W2K that will work under XP
If you think is may be a faulty slot check the slot with another board and see if it will work
Check to make sure thatyou have the correct display settings for the monitor,should be set to SVGA,then check the Refresh settings to see if adjusting would help

The RAM is in there fine. This is a brand-new computer. I'm building it. It doesn't have an OS because I can't boot it up. I think now that it may be a faulty Power Supply Unit.

I would agree that if you've elimiated the obvious...socket lever slightly ajar, bad ram, bad video card...that you're looking at a screwy power supply. In all actuality, the power supply might be fine, but AMDs seem to be pretty touchy and requireat least a 300 watt for use with other periphials on it.

I just bought an MSI board with a 1500+, thought I was grounding in the case at first because it was powered on in the store, changed a power supply and all worked fine. Before. Before,nothing was happening with it.

I've never really payed attention to manufacturers, but a decent plain vanilla 300 watt should cost you around 30 or 40 dollars. Personally, if you have a couple of HDs, a CD and a CDRW, I'd be getting a 350 or 400.

Now,I am confused to what you are trying to ask in your Post,you stated you boot the computer and it gives you a blank screen,then you mention in your comments that you have no operating system on the machine,if this is the case you will not see anything,load a operating system before buying a new PSU,after this then get a compatible one 350w

Check previous post by using the search in the upper right corner,a similar problem was posted and it had to do with a jumper on the motherboard,for the power settings

You are mistaken. Even though there is no OS, I should still be able to see the BIOS. Do some research before answering problematic questions.

Thanks for the info and I will take your suggestion to do Research,sorrry I did not know this

Hi have you tried a different make/type graphics card even a pci card to see if you get the bios screen,this will help you see if it is a compatability problem.

Am I correct in assuming that this is a newly assembled system? And that it has had a blank screen from the first time that you tried to boot it?

If so, double check all of the basics, jumpers, connectors, etc.

Then, clear the CMOS. Set thejumper, and turn on the system if needed. Or, remove the battery for several minutes.

Drop back to a minimum configuration. Have just the CPU, 1 memory module, video card. No other cards, cables, or drives.

Check the voltages from the powersupply. Double check the 120/220 switch on the power supply.

While rare, it is not impossible that PSU, CPU, MB, or memory is defective.

As to a good power supply, check out the recommended supplies listed on AMDs site.
If the supply has theAMD sticker, it has received approval from AMD.
I have 2 Leadman supplies that I am pleased with. Figure $40 retail for a 300 Watt.

I had the same problem, may not answer yours. I just set the heat sink to the athlon, but forgot to secure it with the lock down handle. I powered it up once and thats all it took to fry the processor. I did bot know it at the time and thought the same. Bad AGP slot on Board. I did all the switching around. finally I got a new system board, Proccessor and ram. Installed everything and clamped down the chip . everything works. I called AMD and they confirmed that if you do not secure the heat sink fan to the processer it will fry the chip, and possibly the system board.. Like I stated this may not help

Please don't take this wrong but, i recently had encountered the same problem with a system a customer had built. Did you insure that on first boot the CMOS jumper (JP4) was shorted correctly? I went through a dozen differant tests before I took thetime to quiz the customer on each step of his build. He admitted that he "fixed" the jumper after the first post attempt. Anew board (K7S5A) booted immediately. ECS is shipping a warning sheet with the newer boards now. I would try all else on another board if you can get one.

Hi
There is a little light near your monitor's on/off button. This is called the "synch light," and it usually displays three states: 1- Dark means that the monitor doesn't have any power or can not function.2- Green means that the monitor is receiving and displaying the signal from the video card.3- Amber means that either there is no detectable video signal, or that the monitor is intentionally sleeping.Depnding in what you see you could elmnate the problem.TO me i woud go step by step: Firat conform that the motherboard is not unintintionly touching the case.Then confirm that all parts CPU, display card, memory, Hard disk cables are seated and connectit.Check CPU power and clock setting as the manual say,disk Jumbers,check power out let and cable to amke sure power is comming in.Check power suply to see if it givin power tot motheboard.Check power is comming to monitor and the cable is not cut specially near connection.my sespesion if it it is not bad motherboard, CPU, memory, and a bad hardisk or jumber setting Then it is one of these. A cable is not connect so unplge all cable one by one, specially POWER, monitor, and HARD DISK and set the hard disk jumber and make sure power suply voltage is right and giving the right voltage to mother board and cpu.See if any cable has a missing pin or bent one specially for har disk and monitor.last but not least CPU speed setting (overclocked or under clocked).

good luck

Mohamed.

Do you know if your Monitor is a high res model?
I have a 21" Hp monitor that remains blank until windows has loaded. The monitor only came on when prompted for a network password. I was using this monitor with a new system that I had just built, It was powering up ok but did not allow me access to the bios, which was needed for hard-drive detection. Try switching monitors before spending anymore money, If it helps then load your OS and change your monitor setting. If you have access to the internet download a small utility called pc check You might find it useful good luck!
