Viewsonic VP171b problems

[PENGUINwithM4A1]

Hi, ive had this monitor for about 2 months now but over the past 3 weeks its been going very bright for 3 seconds then goes VERY dark as if the internal light has gone or something, it also makes a high pitches squeel before it goes. Turning it off then straight back on makes a high pitched squeel for about 3 seconds then goes back to the dark state, the only way to get it to come back is to turn it off for about 2 minutes which isnt helpfull when playing FPS or WoW

Nvida GeForce 6800GS PCIe
Viewsonic VP171b
AMD Athlon 3200 venice
Corsair PC3200 2x512 ProXL
Abit KN8 mobo

Please help this is driving me nuts

all i can suggest is try it on another PC and see if it does the same? Also check if it matters whether you're using DVI or VGA

if not, then chances are you might need to contact ViewSonic for an RMA
