If the PC sounds like it is booting with the blank screen it could be the monitor. Try using that monitor on the other PC and see if it works there. If it does, then I would say it is a heat problem or PSU. Can you have the PSU checked? Try swapping it out with the other PC. <===Lefty=== AMD 64 3200+ 200 GB WD Geforce 5500FX 256 MB 512 MB Ram Needs more. Windows XP

If you can view the BIOS screen but the screen goes blank from there, the display setting in the BIOS is probably wrong, especially if you reset CMOS & didn't go back & correct it. It's either set to onboard when you're using AGP, or AGP when you're using onboard...it may even be set to PCI.

I put new PSU and also changed onboard pci/agp to agp/pci.i noticed hardware monitor of bios that vcore voltage keeps changing number and color white to red.i am still facing same problem.please help me SOHEL AHMAD.

So it isn't the monitor,PSU and you changed the BIOS to use the AGP graphics! Have you tested the memory? memtest86.com has a floppy or CD version. Did you mess around with the BIOS setup screens at all? What you might try is set them back to default and then of course change the Graphics back to AGP. <===Lefty=== AMD 64 3200+ 200 GB WD Geforce 5500FX 256 MB 512 MB Ram Needs more. Windows XP

i took off all of my hard disk.then i tried to boot from cdrom to check memory by using memtest86.but memtest86 stops as soon as it starts scanning.what do you think about it? SOHEL AHMAD.
