I recently did a fresh install of windows xp on my hp pavillion a1000n and everything was working great but when i turn off the computer and TRY to turn it back on it gets stuck on the hp LOGO screen and i cant do anything but to manually turn it back off, problem is it keeps doing it over and over untill i disconnect the cable from the power supply then connect it back and then turn the computer on.

So i thought it was the power supply and i changed it...but sadly it keeps doing the same thing.

Any suggestions??
i would really apreciate any opinions.
thank you.Well, it certainly sounds like a hardware problem. I'd run a diagnostic on the ram, video card, hd, etc. You can start by booting to the Recovery Console and running chkdsk /r. Then you can download memtest (or something similar) for the ram.Thanx a lot for your help...however i already removed the pci cards tested the ram even changed the ram, changed hard drive ran chkdsk /r...and for some reason it still gets stuck on the hp screen.
im thinking, since i already checked everything else that is either the mobo or the processor...but i was wondering if theres any way to check these two so that i KNOW which ONE to change.

any help is much apreciated.http://www.ehow.com/how_4867905_test-processor.htmlQuote from: marvin_313 on November 16, 2009, 10:51:54 PM
